Purpose
Radio Frequency Identification (RFID) avoids the limitations of barcode scanning, which requires line-of-sight access to each barcode and can only be used to scan one item at a time.
Scanning one tag at a time can be tiresome and stressful, which increases the chance of human error. Instead, RFID tags do not require a direct line of sight, and multiple RFID tags can be located and read remotely and simultaneously.
Liquid UI’s RFID feature can be used with online and offline solutions to save time and enhance stock accuracy, thus boosting revenue and profits. Here, the connected Zebra RFID scanner will detect and identify objects.
How to use
You can scan RFID tags using the Zebra RFID scanner in any of the following ways:
- Press the trigger on your RFID reader when you are in any SAP transaction. Then, the attached Zebra RFID scanner will scan the RFID tags and automatically copy the tag to the RFID reader screen. You can copy a single tag for Input Fields and multiple tags for long text and clipboards.
Note: Actions can be performed only if the focus was on any Input Field or long text field when you pressed the trigger.
- Open Liquid UI for Android app and navigate to any SAP transaction. For instance, here we have navigated to VA01 (Create Sales Order: Initial Screen). You can see the RFID option on any SAP Input Field pop-up, as shown below.
- Select the RFID option from the corresponding popup menu to navigate to the Liquid UI RFID Reader screen. If the connection is a success, appears the following screen. Then, you can proceed with scanning.
