Features & functions

The keyfob contains the NTAG 213, which has a memory capacity of 180 byte (NDEF: 137 byte) and can be encoded up to 100,000 times. This chip comes along with the UID ASCII Mirror Feature, which allows to attach the UID of the chip to the NDEF message. Additionally, the chip contains a NFC counter, which counts the times a NFC tag is read. Both functions are deactivated by default.
