NFC Keyfob, 40 x 32 mm, MIFARE DESFire EV2 4K, black
You are looking for the ideal keyfob for security applications? The NXP DESFire EV2 4K keyfob encrypts all stored data securely and also allows you to store more than just one application on the built-in NFC chip. Thus, the keyfob is well suited for intelligent lock systems, access control, recording of working times, contactless payment or public transport ticketing systems. The chipset of this keyfob functions well with all common NFC-enabled smartphones.
The black NFC Keyfob is made of ABS, so it is very robust and fully waterproof. The keyfob has a length of 40 mm, a width of 32 mm and a thickness of 4.3 mm overall. Additionally, the keyfob has a ring out of metal, so it can be attached at a key ring. The NFC microchip is integrated inside the product.
