About this item

The keychain is equipped with an EM4100 chip and engraved with a unique ten digit code.
When placed in an alternating electromagnetic field with a frequency of 125kHz, the EM4100 card can sense energy and drive it, and the change in its built-in antenna loop can achieve data transmission with the card reader.
In terms of application areas, EM4100 cards are widely used in various situations that require identity recognition and data reading, such as access control systems, library borrowing, etc.
Attention: EM4100 can only read and cannot erase
The internal ROM of the EM4100 chip stores 10 decimal card number data, which makes the EM4100 card unique.
