Abstract
Authenticating physical presence in a transaction or exchange of data using NFC is well supported between smart-phone and static hardware such as a Point of Sale (POS) terminal. The same interaction between two smart-phones is more cumbersome due to the placement of the RFID chip within phones. Furthermore, Apple have restricted developer access to the NFC capability shipped within their phones. In this brief talk I will introduce the technology used in an app called nibble.io which uses inaudible high-frequency sound to verify device proximity.
Series This talk is part of the Computer Laboratory NetOS Group Talklets series.
