In order for the users to find objects more efficiently, {{UBIK}} objects can be marked with values for RFID codes. Whenever a user scans an optical code, the resulting code value can be used to find all matching objects, namely objects that have the [[#Technical_background|right property]].
In order for the users to find objects more efficiently, {{UBIK}} objects can be marked with values for RFID codes. Whenever a user scans an RFID code, the resulting code value can be used to find all matching objects, namely objects that have the [[#Technical_background|right property]]. This feature is available since {{Version/Android|2.4.2}} . == Introduction: RFID & NFC == [http://en.wikipedia.org/wiki/Near_field_communication NFC] stands for "Near Field Communication" and is a set of ideas and technologies for data transfer between devices, typically in close distances.Technically, it is based on [http://en.wikipedia.org/wiki/Radio-frequency_identification RFID] ("Radio-Frequency Identification"), which describes specific technical solutions. Amongst the use cases for NFC, there is communication between smartphones and other devices, but also the scanning of RFID tags. The {{UBIK}} RFID scanning feature specifically is the ability to scan RFID tags in order to identify {{UBIK}} objects. == Supported RFID Tags == There are three types of RFID markers supported by {{UBIK}}:* NfcA (RFID standard: ISO-14443A) {{Version/WinXAndroidSince|2.54.2}}* NfcB (RFID standard: ISO-14443B) {{Version/AndroidSince|2.4.5}}* NfcV (RFID standard: ISO-15693) {{Version/AndroidSince|2.4.5}}

Once an the ID of the tag is scanned, {{UBIK}} starts searching for objects with the scanned RFID.
# During the search, the list might show a searching text before any objects are found;
# If any objects are found, they will be displayed in a list. The users can then browse to any of the objects for more information by clicking on the objects;

Once a tag is successfully scanned, an object search is executed based on the scanned texttag´s NDEF message.
# if no objects are found a message is poping up at the right side of the screen.
# if more than one object is found the results are represented in a dialog along with their matching probability. One can than select one object that should be opened in the content browser.
