This feature Amongst the use cases for NFC, there is available since {{Version/Android|2.4.2}}communication between smartphones and other devices, but also the scanning of RFID tags.

== Search modes == {{UBIK}} provides two mechanisms modes for searching objects: [[Sync Mode#Possible sync modes|online and offline]].

When the Internet is available avaiable and {{UBIK}} is not running under offline mode, the search result is enhanced by online search. This means any objects that match the scanned results can be found even if they don't yet exist locally.
