125KHz RFID Tag – 5pcs is used for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications. This basic RFID tag works in the 125kHz RF range and comes with a unique 32-bit ID. It is not re-programmable. This blank, smooth, and mildly flexible RFID tag is ready for your logo (or hand-drawn scribble).
Operating on a frequency of 125kHz, these tokens are all pre-programmed with unique ID numbers to communicate wirelessly with RFID Readers over distances of around 10 cm or less. This means you can attach it to vehicles or items, keyrings or even pets’ collars to keep track of the location via an array of readers in the office, warehouse or home.
Each RFID Tag comes attached to a small keyring, within a little blue housing. This 125KHz RFID Tag makes them easy to distribute while maintaining a fair amount of discretion. Additionally, the process of matching tags to readers is also very simple as well, as all you have to do is tell the RFID Reader that you are adding a token, and then hold the token nearby. Then, when the token passes by the reader, the system can identify and log the ID number and time, or can even open up doors or other access ways automatically.
