Epoxy NFC key fobs with a NTAG213 chip
(Product ID: 3208)

These robust 50 x 25 mm NFC key fobs have an approx. 1 mm thick polyurethane (epoxy) layer on top of each side which protects the printed artwork and makes them very nice looking.

The 5 mm hole allows the key fobs to be attached to a keychain, ring, or other pendants.

They are waterproof and ideal for opening doors with smart locks and identify users in various NFC applications.

The embedded NFC chip is the well-known NXP NTAG213 chip which operates accordingly to the ISO/IEC 14443 protocol, contains a 7 byte-long unique identification number, and has a user memory of 144 bytes – which is equal to a 136 character-long URL address or other text.

Smart locks and identification apps usually use for authentication the unique identification number, but you may use the same key fobs also for other purposes.

They can open URL links, video links, they can start your navigation to a destination address, they are used for Bluetooth pairing, Wi-Fi configuration, and more.

To program the epoxy key fobs, you can use your mobile phone and a free application like NFC Tools, NXP TagWriter, or others.

You can purchase the NFC key fobs with generic artwork online or send us an inquiry for personalized key fobs with your company logo, serial numbers, etc. The minimum quantity for personalized epoxy key fobs is 100 pcs.
