Nfc technology how does it work

NFC is capable of so many tap-and-go functions — digital wallets like Apple Pay, Google Pay, and Samsung Pay cover just a tiny fraction of its capabilities.

NFC is the technology that enables contactless payments. NFC is actually a subset of something called RFID radio-frequency identification , a technology that allows us to identify things through radio waves.

To date, one of the more common uses for NFC is identification cards to gain access to places like office buildings and private garages. A contactless payment is a transaction that requires no physical contact between a device aka a smartphone and a payments terminal. Meaning, people can just hold up their mobile devices to pay. For a contactless payment to go off seamlessly, you usually have to hold your phone two inches or less from the reader.

When a contactless payment is initiated by a customer holding or tapping a mobile device to the payments terminal , the NFC technology goes to work. Using that specific frequency we talked about, the NFC-enabled reader and the smartphone pass encrypted information back and forth to each other to complete the payment. This all takes just seconds. Speed, in fact, is one of the coolest parts of NFC payments. They take a fraction of the time of magstripe and chip card transactions—and are leagues faster than cash.

But NFC payments are extremely secure—way more secure, in fact, than magnetic-stripe cards. The banks and networks then replace your bank details with a series of randomly generated numbers the token. That random number is sent back to Apple, which then programs it into your phone.
