What Can An NFC Smart Ring Do?

What is an NFC smart ring?

Near Field Communication (NFC) is a technology that permits the bidirectional transmission of data and instructions over a very short distance, typically a few centimetres. This enables your smartphone to pay for items at a contactless register and communicate with other devices on a fundamental level. Consequently, an NFC smart ring incorporates these capabilities into an item that can be worn on the finger.

How do NFC smart rings work?

Near-field communication is referred to as NFC. A few centimetres separate two devices that use NFC to exchange information such as authentication keys, contact information, and other data. NFC is a subset of the standard for Radio Frequency Identification (RFID). 13.56 MHz is the RFID High Frequency (HF) band at which NFC devices operate.

Manufacturers of NFC devices have transformed the limited read range of its radio frequency into an asset. Because NFC devices must be in close proximity to one another, it is a practical means for communicating securely between all types of smart devices. Also, it is an ideal means to enable contactless payment and access control, among many other use cases.

What does an NFC smart ring do?

Contactless payment. As we’ve already discussed, the primary function of an NFC ring is typically to connect it to your phone and use it to pay for items at checkout. Another popular variation on this theme is to position your hand on the contactless payment sensor at public transport entrances, allowing you to catch your train or bus without having to rummage through your bag or pocket for your smartphone.

Contactless travel pass. Some NFC Smart Rings can be used as contactless travel passes, monthly passes, and season passes for public transport. Using your NFC-enabled Ring, you can tap-to-pay at the transit gates using a card reader terminal.

Contactless Access Badge. One of the primary uses for NFC Smart Rings is to replace access cards and badges at workplaces, enterprises, buildings, schools, and gyms. Now, the NFC Smart Rings can identify and authenticate employees, service personnel, and gym members when they tap the access card readers with a ring to gain access to the proper facilities.

Unlock smart locks. If you’ve invested in smart home technology, you may discover that the NFC ring allows you to unlock doors by simply placing your hand on the sensor. As the Internet of Things becomes a reality, these capabilities may expand to include increased interaction with mobile and smart home devices.
