NFC Wristband is developed to be one of the most advanced NFC products on the market. The most common case is to use it as a student card, membership card or a key access. It can replace all those cards and make your life easier. It is small and light, so you can carry it anywhere.  It is made of P2 material with special anti-metal design, which makes the chip hard to be detected by metal detectors. This wristband will not become invalid like paper cards or stop working like plastic cards. NFC wristband is waterproof; it can still work after being used in water such as in swimming pools or showers.
