RFID - ISO/IEC Standards list
Description:
"A radio-frequency identification system uses tags, or labels attached to the objects to be identified. Two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response. The readers generally transmit their observations to a computer system running RFID software or RFID middleware.RFID tags can be either passive, active or battery assisted passive. An active tag has an on-board battery and periodically transmits its ID signal. A battery assisted passive (BAP) has a small battery on board and is activated when in the presence of a RFID reader."
“射频识别系统使用标签或标签贴在要识别的物体上,称为询问器或阅读器的双向无线电收发器向标签发送信号并读取其响应,读者通常将其观察结果发送给 计算机系统运行RFID软件或RFID中间件。RFID标签可以是被动的,主动的或电池辅助的被动式。有源标签有一个板载电池并周期性地发送其ID信号。电池辅助无源(BAP) 并且在有RFID阅读器的情况下被**。“

NFC - ISO/IEC 18092 and ISO/IEC 14443-2,3,4, JIS X6319-4
Description:
"NFC is a set of short-range wireless technologies, typically requiring a distance of 10 cm or less. NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s.NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target. This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries. NFC peer-to-peer communication is possible, provided both devices are powered"Frequency: 13.56 MHz
Range: < 0.2 m
Examples: Smart Wallets/Cards, Action Tags, Access Control
