How RFID technology can help can help in managing the construction materials

Management of materials is very necessary for the smoothly running any construction project. The most common problems faced by the construction companies are supply delays, material shortages, wastage and lack of storage space. Without proper planning and order, there can be many errors in the projects. RFID (Radio-frequency Identification) can help construction companies in overcoming the issues and frustrations that occur when managing and tracking the materials.


Various RFID components used in managing construction materials:

The traditional methods like paper-based tracking used for tracking materials have lots of problems. The RFID technology helps in overcoming these problems that traditional methods have. There are multiple components in an RFID based tracking system.

A basic RFID based tracking system contains tags and readers. The tags are attached to the physical materials to be tracked, and the reader communicates the data from the tags. The tags become active only in the presence of the readers. However, active tags are also available, which are active all the time, because they have a built-in power supply.  The active is little costly but they also have better readability than the passive tags as they are active all the times.

Using radio frequency, the RFID reader communicates data to and from the RFID tags. The data is then shared with a software system, where it is processed and necessary business decisions can be taken. The RFID tags are placed on the stack of the metal roof panels. The RFID tracking system gives the accurate counts of the panels in the stack. The system is a great way to check the inventory and monitor quantities.

We can also track the location of the panels in a warehouse storage space. In case of multiple storage sites, accessing the materials becomes easy as typing in the information about the item reveal the exact location of the item because it was scanned and keyed in. A different approach will be using different readers attached to different locations.

Systematic analysis of the inventory would also reveal the requirement of the inventory before the construction project starts. The required items can be pre-ordered so the project can start on time, and not be interrupted by having to order the materials in the middle of the project.

RFID material tracking components



Benefits of the RFID tracking system for the construction companies:

RFID based materials tracking system provides many advantages over the traditional methods like paper-based methods. Some of the advantages are:

  • Capturing data in real-time
  • Improving the productivity of the processes
  • Reduction in the paper-work
  • A decrease in material related issues like delay and over-ordering that increases the cost of the project
  • Improved safety practices
  • Better project timing estimate


We can say that using RFID technology to track materials can improve the planning of the projects. When the costumers have a good experience, the company builds good credibility in a long run. Smooth process flow results in good customer experience which in turn means more business.


Areas of construction where RFID technology can help:

Generally, any area of construction industry benefits from RFID. It can reduce the incidences of the lost and duplicate items. The roofing industry, internal and external remodeling, new home building, precast concrete installers, steel industry, garage building companies can all make use of the RFID in all areas of the materials and tool management systems.

RFID tracking system provides better projects in construction

With the help of RFID, one can improve the predictability of the project estimates. The RFID system can definitely help in the kind of project where the system has been used in one project and then a project of similar scope and size is acquired later. The data acquired from the previous project can be used to determine the material requirement of the new project. This analytics can save a considerable amount of the time and keep the costs down for construction companies.

RFID can be used to separate different type of materials like bulk materials,  engineering materials, and prefabricated materials according to the requirements.

Implementing RFID solution can reduce the cost savings

Overall, RFID can be used how materials are tracked and managed in the construction industry. As more people know about the benefits associated with implementing RFID technology to track the materials, its adoption will increase considerably. When companies become cost-effective, they can provide better services to customers effectively.



Benefits of RFID based laundry management system

1. Reduce Manual count and manual work

Big organizations with laundry requirements spend time sorting textiles for the purposes of the laundry. The sorting process is done with the help of 2-8 peoples. With RIFD systems, RIFD tags are attached to clothing item, and when that cloth move through assembly line, an RFID reader sends an signal to read the tag. When the tag is identified, the software determines where that cloth goes next in the process line.

2. Provide Wash Count accurately

The wash cycle of the clothing material help predict the end-of-the-life of the garment.  Most clothing items help withstand a certain number of wash cycle before they start to wear and tear. When there is no record of wash cycle count, predicting the end of the life of the garment and clothing items if difficult which can cause delay in reordering of replacements.

RFID tags are sewed into every new fabric, and when garment is released from the washing machine, RFID readers detect the tags sewed in the garment. This way, the software keep update of wash count cycle. When the software detects the clothing have reached it’s maximum wash cycles, it can notify the user to reorder that type of clothing material. With RFID system in place, the company make sure that each garment or linen are in stock, and therefore there is no lag time.

3. Provide fast Visibility Into Inventory .

Without the proper visibility of the inventory, it becomes hard to run operations efficiently, and prevent items from being lost. If there is no inventory count system in place, there may be inefficiency in the day-to-day operations due to inaccurate inventory.

RFID tags sewed in the clothing items help companies to make inventory count faster and efficient. RFID readers installed in the storage room helps to find the lost items accurately. Counting the inventory before the clothing items received and when it is delivered makes sure nothing is lost in the laundry process.


4. Reduce Loss of the clothing items

Most companies across the world use manual inventory system to keep check on stolen clothing items. Unfortunately, manual counts have lots of human errors present in them. When the counting ceases, and some error comes in the count, the next step is to recognize the error in the system. Usually, when items are lost in the laundry process, there is no way to find the person responsible for it.

With unique code on each RFID tag enable the company to find the exact clothing lost, its last location. If a clothing item was taken from a room in a hotel, the guest can be charged for the linen which ensure company does not make any loss of money on the lost item.

5. Provide Meaningful Customer Information.Heavy_Duty_laundry_-_Ironer_line

Companies that rent textiles can get insights about their customers through the RFID tags on the clothing items. Clothing sewed with RFID tags helps keep track of information such as previous renter, rent date, and rent duration. Keeping the track of these records can enable the company understand item popularity, item history, and customer preferences.

6. Enable Accurate Check-In and Check-Out System

Maintaining the  renting textile business can be complex unless the company installs a proper method to maintain information such as loan date, due date, customer information, and linen information. A RFID software can provide a custom database that not only stores the important information, but also notify the company on the due date. A system with these features allows companies to communicate approximate back-in-stock dates to their customers. Providing customers with approximate instead of assumed return dates improves customer relations.

RFID Technology FAQs

RFID Technology FAQs

What is RFID technology and how it works?


RFID technology


RFID means Radio frequency identification. It is used to track objects, people, and animals. A RFID system consists of three elements: a RFID tag (smart label), a RFID reader and an antenna. RFID tags contain memory and antenna which transfers data in the form of radio waves when in contact with to RFID signals.

What is difference between active and passive RFID?

Active vs passive RFID

The difference between the active RFID and passive RFID is power source. The active RFID have power source which is used to power the circuitry and broadcast signal. Passive RFID doesn’t have a power source. The passive RFID tag gets activated in the presence of RFID readers.


What is meant by RFID tag?

RFID tag

A RFID tag is a small sensor that is attached to objects, people or animals for tracking purposes. A RFID tag can be active or passive based on power source. A RFID tag contains memory and antenna. If it is passive it becomes active in the presence of RFID reader while active RFID is always on and broadcasts signals.

Can RFID tags be reused?

Resusable RFID

People have confusion regarding the reuse of the RFID tags. If  RFID is used in logistics tracking, after the object have been used, tags can be reused to track other objects.


What is RFID tracking?

RFID Tracking

RFID tracking uses RFID tags to track object. The radio waves are used to read data stored on the tag attached to the objects.  The tag can be read from a far distance too, and it doesn’t need to be the line of sight of the reader.


What is RFID scanner?

RFID scanner

RFID scanner is used to scan RFID tags attached to the objects in order to categorize, identify or track assets. It does so by broadcasting radio frequency waves directly, to which the RFID tags present in the range of the scanner gets activated, and send back data.


How far can RFID be read?

The high range frequency tags such as UHF RFID tags can be read over 1 meter to 3 feet. Latest generation tags such as Gen2 tags can read upto 12 metres, and some IC’s plus antenna can be read at the maximum distance of 15 metres!.

How much a RFID tag cost?

RFID tags cost

The cost of RFID tags starts from few rupees to four thousand rupees depending upon the type of tag, where it needs to deployed and the volume of tags needed. Generally, the smart labels and tags needed to track cases and pallets cost around Rs10- Rs100 depending upon the volume.

How much does a RFID reader cost?

RFID reader cost

UHF RFID readers can cost anywhere between $500 and $2000, depending upon the features in the device. You also need to buy antenna, cables and tags separately to make complete RFID system. Antenna can cost around $200 each. The cost of UHF readers is constantly dropping due to increase in adoption of RFID technology.

What blocks RFID?

RFID blocking

RFID can be blocked with many materials which are poor conductors of electromagnetism. RFID blocking can be achieved with the help of aluminum foils. These foils will do the work; you just need more foil sheets to achieve this.

Where are RFID tags used?

RFID uses

RFID tags are being adopted in many industries and in many applications. For example, in automobile industry, the vehicle is tagged with RFID tag, to track its progress across the assembly line; RFID tagged medicines can be tracked through the warehouse, and the hospitals and pharmacies; animals tracked with RFID can be tracked with more productivity.

What is RFID frequency?

RFID frequency

The various frequencies have been assigned to RFID technology. The low frequencies RFID systems work in the assigned band of 125 or 134 kHz and high frequency RFID systems work in the range of 13.56 Mhz. UHF RFID are being used since mid 1990s and the frequency range for this have been agreed upon by the countries.

Can you read NFC with RFID?


An NFC device can act as both a reader and as a tag. NFC devices read the NFC passive tags and some NFC devices can read the passive HF RFID tags that are compliant with ISO 15693.

Can phones read RFID?

RFID and mobile phones

Some android phones can read passive high frequency (RFID) tags under the Near Field Communication Protocol. Company known as Zebra Technologies that makes a sled that works with android phones and can read UHF RFID passive tags.

What’s the difference between RFID and NFC?


RFID is the technology through which items are uniquely identified with the help of radio waves. NFC technology is the specialized subset technology of RFID technology. We can say that NFC is a branch of HF (high frequency) RFID. Both NFC and HF RFID operate at 13.56 MHz frequency.


Do phones have RFID?

No phones don’t have RFID feature when you buy them. Some phones have technology called NFC (Near Field Communication) capability, which can be used to read RFID. The RFID and NFC are similar in range and process, but these two technologies are not always compatible with each other.

How is barcode different from RFID?

Barcodes are designed to read one at a time whereas many RFID tags can be read at a single time. Also bar-codes requires being in line of sight, while RFID is “near field” technology, where tags only need to be in the range of the RFID to be scanned.



Benefits of RFID library management system

Libraries mostly have large amount of inventory which consist of books, CDs and other printed materials. RFID systems are most suitable for library management system. Currently old technologies like bar-codes are currently employed by most of the daily circulation activities.


RFID is the latest technology as compared to bar-code. That can store much more data inside and does not have to in line of sight to be read. It can even be embedded into object like book cover, or the cardboard. A library equipped with RFID technology can save a lot of time, money and energy to it’s staff and workers.

Why Asset tracking in libraries is different

The library is different from warehouses or retail stores in the sense that in warehouses the tags attached to the product are thrown away after the sales. But, the book and other library’s material are used for thousands of time or more. This makes the use of RFID different than other industries, because RFID tags are used for a very long time.

The working of RFID in libraries

Typically following book processing are carried out at the library:

    • Check-in of items:  When an item is returned back by the patron to the library, it must be confirmed by the library database, that the item is available for future check out. A receipt is also issued to the the patron, for confirming he/she have returned the item on given date.
    • Check-out of items: If a patron  borrow a library item, it must be confirmed by the library information system, that the item is being borrowed.  The data of return can also be registered with the system.
    • Prevent thefts: during the check-out and after the check-in of items, the security must be turned on to prevent the unnecessary theft of the library’s items. In the case of theft attempt, an alarm gets activated.
    • Shelving returned items: first, the received items need to be sorted based on their shelf address for convenience and time saving. Then, these must be shelved to the predetermined address, so that a patron can find it for check-out.
    • Inventory check and counting: In an conventional library information system, the items in the collection are being counted usually once a year, to determine any missing items. In old systems with the bar-code tags,  are located inside of the books, this takes up lots of labor and time of staff.
    • Inter-library loan service (ILL):  Thorough this process, a user of one library can borrow books that are owned by other libraries
    • Classification and cataloging new items: The new items added to library collection must be cataloged before placing them in library.  It must be given a unique ID number and it must defined inside the library information system.


Putting returned items in shelves, check in and check out related tasks are done on a daily basis. Depending upon the size of collection of items and number of patrons, this work requires large amount of time.

Benefits of RFID Library systems

The costs are saved in terms of labor and theft/missing items. The time of patrons is also saved when using RFID systems in the library:

  1. Some libraries implemented self-check-in and self-check-out with installation of extra hardware. By putting this system into use, the library could provide twenty-four hour book circulation services to the patrons, and the staff is relieved of the routine repetitive tasks. This motivates the library staff to work for more user-oriented and value-added services.
  2. The RFID system also decrease the occurrences of theft and missing items. Installing RFID security gates will ensure nothing gets out without being registered with library information system. With the help of RFID technology, missing items, can be found easily. This provides some savings to the library.
  3. Savings by reduced waiting times. During busy periods of the libraries, patrons accumulate through the waiting lines, in front of the circulation desk.

With the RFID technology, not only the cost decreases with reduced theft and less human labor, it also gives flexibility to the patrons. Now the patrons can borrow the books anytime without the intervention of humans.



RFID based automation in jewellery manufacturing

Manufacturing of precious and high value jewellery requires issue of raw materials, checking its quality along the chain, maintaining its inventory and lots of more things. These processes require constant monitoring through manpower and valuable time of the company. By investing in Radio Frequency Identification (RFID) technology, the jewellery businesses can improve their productivity, can cut off manual work, and get good return on the investment (ROI).

Currently the whole process of monitoring is done with the help of manpower. The supervisor takes the raw materially manually at each shop floor; it then keeps record of it in traditional way and then provides it to the workers who make the jewellery. After the jewellery is built, it is then sent for the article QC check where every jewellery item is checked against the given standards. And finally the inventory of the finished jewellery items is tracked and sent to retail stores for sales.

The Radio Identification (RFID) technology can drastically decrease the number of steps from procurement of raw materials to delivery of raw materials. It not only decreases the time of manufacturing but also increases the productivity and is proving itself a great mechanism against the jewellery theft control in the whole production, retail and sale cycle.


With the help of RFID the whole process became automated, and manual work is reduced hugely. The employees are required only for issuing and receiving materials. Everything is tracked and monitored in real time and movement of jewellery item is captured on the shop floor using automated process.


The jewellery management system consists following components:

  • IMPNJ RFID readers – which can are installed on shop floors,
  • The RFID tags – which are inserted in materials and jewellery items.
  • The antennas -which get signals from jewellery items and sends it to RFID readers
  • RFID software – Which collects and analyses data



Now there is real time control on accountability on who is doing what, when, where without the need of manual entry of data. The testing of finished materials and procurement of raw materials is also fully automated.

This new technology is proving to be very beneficial for the jewellery industry and providing a great return on investment to businesses who are implementing these solutions. It just need to be implemented one time and provides benefits for long time without much maintenance. The RFID tracking system for production can be integrated with any ERP and SAP software.  If you are looking for implementing Jewellery tracking software you can consult us.
