NFC-chip is a small flat (round or square) chip made of flexible materials. Compact size allows the chip to be mounted even in ultra-thin iPhone models. Technology of activation and interaction based on the generation of electromagnetic field at short distances. Generation is through a special loop antenna installed in both the source and the consumer. Not all iPhone models are available with proximity function.

Option is supported from iPhone 5s and higher.

Technical parameters of the chips in the iPhone

Parameter Unit. measurements Value
Minimum distance for interaction see 0,5
Maximum distance for interaction see 20
Data encoding method Manchester
