As our most popular NFC Keyfob is made of waterproof material and sustains temperatures between -25 °C and 70 °C, it is well suited for outdoor usage. For example it can be used to control access on construction sites or record working times of employees outdoors. The chipset of this keyfob functions well with all common NFC-enabled smartphones. The 7Byte UID of the chip is printed on the back of the keyfob.
The blue NFC Keyfob is made of ABS, so it is very robust and fully waterproof. The keyfob has a length of 37 mm, a width of 30 mm and a thickness of 8 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.
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. Further information about this chip and other NFC chip types you can find here. We also provide you with a download of the technical documentation by NXP.
These are a few examples for possible applications of the keyfob.
– Control access indoors and outdoors
– Record working times (e.g. on construction sites)
– Start various apps on your smartphone (e.g. activate an alarm)
