NFC came out of RFID, which uses electromagnetic induction in order to transmit information over a short space]]> 2018-07-16 05:37:40 UTC https://padlet.com/mmz11493/ljp6mcu3pj2p/wish/270279478 mmz11493 https://padlet.com/mmz11493/ljp6mcu3pj2p/wish/270279592 NFC is a means of sending data over radio waves. In that sense it is similar to Wi-Fi or Bluetooth, but unlike those protocols (and like RFID) NFC can be used to induce electric currents within passive components as well as just send data. And it is faster than Bluetooth, in general.]]> 2018-07-16 05:40:29 UTC https://padlet.com/mmz11493/ljp6mcu3pj2p/wish/270279592 mmz11493 https://padlet.com/mmz11493/ljp6mcu3pj2p/wish/270280064 1. Peer-to-peer mode: that lets two smartphones swap data.

2. Read/write mode: one active device picks up info from a passive one.

3. Card emulation: NFC device such as a smartphone can be used like a contactless credit card.]]> 2018-07-16 05:52:07 UTC https://padlet.com/mmz11493/ljp6mcu3pj2p/wish/270280064
