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.

For example, when embedded into garments, CIRCUS DURA can survive multiple washing and drying cycles, making it ideal for wash-and-wear applications in clothing and footwear industries. Its unique ID UID makes the inlay perfectly suited for high-volume product authentication and other marketing applications.
The basic unit of information used in memory management is called a block. Each block has a fixed size of 16 bytes. The number of memory blocks available depends on the chip hardware. Memory blocks are not addressed directly, but relative to the service they belong to. Containing data collision protection, NFC type 1 tags can be set to be either rewritable or read-only. Type 1 tags come with a lower market price and do not support the anti-collision mechanism.
However, the memory size for these tags range from 48 bytes to 2 KB, and the they do support the anti-collision mechanism. Type 3 NFC tags have more memory and faster speeds than type 1 and 2 tags. Type 3 tags can be set to either read-only or rewritable mode, support the anti-collision mechanism, and contain 2 KB of memory. They are factory-set to read-only mode, and require specific service equipment to update their data.
Users read the NFC tags by tapping their iPhone to it. For iPhone 7 through 10, the process is much the same, except an app, like Decode , is required to read NFC.
