Troubleshooting

RFID tag reading problems

Symptom

Solution

System doesn’t read tags

• Make sure the item is tagged with 3M RFID tags.

• Make sure the tag is not blank or disabled by trying a tag known

to be good.

• Make sure you are placing the tag within the read range of the

RFID pad by placing the tag in the middle of the pad.

System doesn’t read a particular
tag type

The tag type may not be configured. Call 3M service.

Pad read range reduced to less
than 6 in [15 cm]

Make sure the pad is at least 2 in. [5 cm] from metal.

Barcode scanner problems

• If the scanner has a poor read rate, check for dust and fingerprints on the scanner window and clean if necessary with a clean,

dry cotton-tip swab or cloth.

• If the scanner can’t read a particular barcode symbology, add the new symbology. See the scanner documentation for information.
