Near Field Communication (NFC) is an international transmission standard based on RFID (radio-frequency identification) technology for contactless data exchange using electromagnetic induction over short distances of a few centimetres. This requirement means that data transmission is very secure and is used in particular for contactless payments/micropayments for small amounts via a smartphone. In the area of IoT (Internet of Things), new application options are also being developed with NFC, such as connecting to de-energized devices or simpler user control.
