The iPhone comes with a built-in NFC tags reader that can be used to power NFC-enabled payments and read NFC tags attached to real-world objects.

Using an NFC Tags Reader on the iPhone

NFC (Near Field Communication) is a radio technology designed to facilitate contactless data transfer over short distances (1.6 inches or less) between two devices/objects.

NFC connections are harder to eavesdrop on than RFID (Radio Frequency Identification) since data exchange can only take place when the two devices are in close proximity to each other.

As a result, the technology is used in contactless payment systems and is supported by Apple, Samsung, Microsoft, Google and other device manufacturers.

What areNFC tags?

NFC tags are basically tags with a radio chip that can store data in NFC format and communicate with other NFC-enabled devices using a small antenna connected to the NFC chip.

NFC tags are small, inexpensive, and easily attached to posters, game passes, business cards, and other types of products or real-world objects.

Blank rewritable NFC tags can be purchased in bulk at very low prices and rewritten thousands of times or written once and then shielded to prevent them from being overwritten.

Currently, there are 5 types of NFC tags with different storage capacities (93 bytes, 2 KB, 32 and 64 KB) and data transfer rates (26.48, 106, 212 and 424 kbits/sec).

What is an NFC tags reader on iPhone?

Similar to RFID tags, NFC tags contain information in NFC format and can be read by NFC-enabled devices.

When an NFC-enabled device is brought close to an NFC tag, it magnetically energizes and transmits its data to the NFC-enabled device.

Both iPhones and Android phones have active NFC chips that can be used to read information from NFC tags, exchange information with NFC-compatible devices, and change information on authorized NFC tags.

Standard NFC functionality on iPhone can be used to perform secure and contactless transactions, access digital content, activate coupons, concert tickets, loyalty programs and other NFC-enabled mobile marketing programs.
