NFC - Near Field Communication, or NFC for short, is a wireless transmission technology used for contactless data exchange between devices with a distance of up to 4 centimeters. NFC has already been specified by the responsible standardization bodies (ISO 18092, ECMA 340, ETSI TS 102 190). NFC dates back to 2002 and was developed by former Philips subsidiary NXP and Sony. Standards such as Bluetooth and RFID were used. Philips, Sony and other companies organized on the NFC Forum are involved in further development of NFC. NFC can transmit up to 424 kbit/s, which is not sufficient for extensive data such as photos or videos. Therefore, the typical applications of NFC are the exchange of information between two devices held close together. For example, you can provide access to content and implement services such as cashless payments or ticketing. Until now, standards and industry-wide cooperation have been lacking for these applications. Technology: frequency band: 13.56 MHz (license-free), transfer rate: 106 kbit/s, 212 kbit/s and 424 kbit/s, range: up to 10 centimeters, operating modes: read-write mode, peer-to-peer mode , Card emulation mode. The radio standard NFC is specially designed for a short range in the range of centimeters to make it difficult to spy on the transmitted data. Because of the extremely short distance, unintended connections are almost impossible. NFC operates in the frequency band of 13.56 MHz with a maximum transmission rate of 424 kbit/s and a range of 10 to 20 centimeters. Technically, NFC can be compared to RFID. The two radio systems do not compete with each other. RFID is usually used with a range of more than one meter. Each NFC device supports two modes of operation. In addition to passive chips accessed by powered active readers, NFC devices operate in both active and passive modes
