In order for the users to find objects more efficiently, one can mark UBIK® objects with certain properties. Whenever a user scans a RFID tag with the UBIK® Android client, the resulting ID value can be used to find all matching objects, namely objects that have the right property.

Introduction: RFID & NFC
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 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® Android 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® Android:
- NfcA (RFID standard: ISO-14443A) ()
- NfcB (RFID standard: ISO-14443B) ()
- NfcV (RFID standard: ISO-15693) ()
Supported Devices
Currently, all devices with standard Android NFC reader access are supported, as well as the Getac Z710 rugged tablet with a built-in RFID reading module accessed by the proprietary Getac SDK.
 | Not all Getac Z710 devices do have an RFID reading module. |
Search modes
UBIK® provides two modes for searching objects: online and offline.
Searching offline
In any case (regardless of the network connection and sync mode), UBIK® always goes through all the objects currently available on the device and find the ones that match the scanned results.
Searching online
When the Internet is 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.
Search result
Once the objects are found, they are displayed in a list. The users can then browse to any of the objects for more information by clicking on the objects.
Classifications
In order for objects to be identifiable through RFID, they have to carry the SYSCLS OBJECTWITHRFIDTAG classification.
The service query used for online searching is SYSCLS RFIDTAGSCANQUERY.
