Use this feature to pair an animal's electronic ID (eID) with its SmartTag using a handheld reader. The reader supports ISO and NFC tag types. You can also use the Visual ID feature for animals without a scannable eID.
You can export scanned tag pairs as a .csv file and import them into your herd management system.

ISO | - SmartTag Neck with Identification (IFER, IFERP). - eID starting with 984. - Third-party eIDs. |
NFC | - Nedap SmartTag Ear. - SmartTag Neck without Identification (FER, FE). |
Visual ID | Animals without eID or with broken eID. |
Ensure your reader is set up and connected. See, Connect your Handheld Reader.

Scan the first tag. You’ll hear one beep. This confirms the first tag was scanned. The app shows the tag number.
For ISO tags, hold the reader close to the tag.
For NFC tags, old the tag against the rectangle on the back of the reader, indicated with a 'NFC' sticker.
NoteThe reader automatically starts with ISO detection, and automatically switches between NFC and ISO detection, depending on which type is expected next. Therefore the order of scanning an eID or SmartTag does not matter.
Exception: If the eID starts with 984, always scan the eID first.
Scan the second tag.
Repeat these steps for all tag pairs.
Select Finish.
