NFC technology enables simple and safe two-way interactions between electronic devices, allowing consumers to perform contactless transactions, access digital content, and connect electronic devices with a single touch. NFC complements many popular consumer level wireless technologies, by utilizing the key elements in existing standards for contactless card technology. NFC can be compatible with existing contactless card infrastructure and it enables a consumer to utilize one device across different systems.
Contactless smart cards incorporate a chip (microprocessor) that communicates with a card reader through RFID technology. Examples of contactless smart card communications are ISO/IEC 14443 and FeliCa, which allow communications at distances up to 10 cm.
NFC technology harmonizes today’s diverse contactless technologies, enabling solutions in areas such as information collection and exchange, Access Control, healthcare, loyalty and coupons, transportation, payments, and consumer electronics.
NFC-enabled devices are unique in that they can support three modes of operation: card emulation, peer-to-peer, and reader/writer. The NFC Forum technical specifications unlock the full capabilities of NFC technology for the different operating modes.
