These UHF RFID Tags make that technology that was so out of reach, affordable and easy to implement into your home or project! RFID has been around for a few years now, however most hobbyists were priced out due to high initial costs. Not anymore we say!

Working in conjunction with our Simultaneous RFID reader, the ultra-thin EPCglobal Gen2 tags can stick to literally anything you want, allowing you to track and trace any object as it passes the reader (We do not condone sticking these on unruly teenagers). The tags can be read and written to, as well as having a kill feature. Each tag is encoded with a Truly unique ID (TID for short) which cannot be edited, however there’s a ton of memory for you to read and write from.

Looking for the TID?

The TID is a bank on the reader that isn’t normally back-scattered during an inventory operation; It’s usually in the back.

The EPC is by default 24 hex characters back to the user and is freely changeable by default. It is what is sent back and most readily seen when a large population of tags is “Inventoried”. (It (EPC) can be changed to broadcast back more or less using the protocol control words on the tag)

What’s UHF?

Not to be confused with the Weird Al’ Yankovic film of the same name. UHF or Ultra high frequency are in the range of 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter). UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.
