Rfid
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® 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® RFID scanning feature specifically is the ability to scan RFID tags in order to identify UBIK® objects.
Supported RFID Tags
The client uses NDEF (NFC Data Exchange Format) for maximum compatibilty between NFC devices, tag types, and operating systems.
Supported Devices
When your client supports NFC, you can see this by opening the side menu. If NFC is supported, a button for enabling/disabling NFC is shown on the top.
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
If the device is placed near an NFC Tag (and NFC is turned on), a search is triggered automatically. The side menu will open up and show the results. If there is exactly one result, the client automatically navigates to that object, if there are more results, the user can select the object out of the list.
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.
