How to get RFID

That depends on what you want to achieve with RFID.  Some systems are simple off-the-shelf purchases and some require more research to ensure the best results.  We don’t sell RFID systems, but we do recommend systems based on your needs.  The best place to start is our RFID Needs Assessment. You can find it

HERE

Based on the information you provide we will either recommend a system you can buy or suggest a further analysis of your assets to ascertain the best system for you.

 

How does passive RFID work?

Passive RFID tags are powered by an electromagnet signal that is transmitted from the reader. They use the signal from the reader to charge the tags capacitor, supplying the power needed to communicate.

How does active RFID work?

Active RFID tags are self-powered, allowing the tag to have a larger communication distance and more memory capabilities.

Can RFID tags be tracked?

Yes. Active tags can tell you that an item is within 300 feet of a reader, but there are also active RFID real-time location systems (RTLS) that can tell you a tags location. Usually within an impressive 10 feet.

Can RFID tags track equipment?

Yes. Depending on the RFID system you choose, RFID tracking equipment will automatically update the location of your assets within a database.

Can RFID be used for Vehicle tracking?

RFID tags are mounted on vehicles and fixed RFID infrastructure is placed at strategic locations such as entry/ exit gates, weigh-bridges, parking lots and equipment. This allows completely automated wireless identification of vehicles without impacting on existing vehicle processes.

Can RFID be used as GPS?

No, RFID is not the same as GPS.  There are some systems that utilize various methods to enable tags to be tracked through certain points, the RFID tag itself will not contain a GPS tracking capability.

Can RFID track location?

Not every RFID solution can track the location of an item but Real Time Location Systems (RTLS) can. RTLS is a solution that’s used to identify or track assets in real time in a chosen space. This could be an office building or warehouse etc. This type of technology can be used to track tools, large machinery, packages and even people, and can tell you the location of the tagged item within an area. As the tagged asset moves it sends a transmission to a fixed receiver highlighting the location of the tag.

How does RFID asset tracking work?

RFID quickly improves asset management by utilising its technology to automatically track assets. An RFID asset tracking system transmits data using an electromagnetic field from an RFID tag to a reader. From the construction industry to library services, RFID asset tagging has huge advantages when it comes to real-time tracking, logistics management, data capture, inventory and distribution.

Using a portable RFID reader, usually built into a mobile computer, you can easily scan one or more tagged assets without having line of sight. An RFID reader can be several feet away from the tagged asset and still get an accurate scan. The RFID tags also have a memory chip installed allowing storage of an item’s; location, serial number, manufacturer, photo, use history and even a maintenance schedule. And with an operational RFID based asset tracking / management system, you have a live asset database that’s accurate.

How can RFID improve supply chain management?

RFID can improve visibility from the point of manufacture, throughout the supply chain and within stores, right from the stock room to the shop floor. Even to the point it leaves the store at sale.

Every supply chain asset can be uniquely identified by; size, colour, type and manufacturer etc. This allows for effective inventory control and visibility, allowing retailers to increase sales and reduce out of stock items both in store and online.

How does RFID help in inventory management?

RFID provides quick, precise identification for inventory management. It allows items to be identified faster and much more reliably. The speed of data capture using an RFID system is less than 5% of the time taken in a manual process and stores have shown an 8% – 10% sales growth from knowing what they have in real time. Using RFID technology for real time stock analysis means popular items don’t run out of stock and you know where your assets are at all times.

How does RFID work in a library?

In libraries RFID tags replace both the EM security strips and barcode on each book and AV item. Providing the ability for self check out / check in, advanced anti theft detection and high-speed inventory checking.

 

Can RFID reader read NFC?

NFC refers to Near Field Communication, most modern smartphones incorporate NFC within them.  So you can use an NFC device to read RFID information but an RFID reader would need something to actually read, NFC is simply the communication method not actual data.

Can RFID tags be reprogrammed?
