Please see out help article on Barcode Scanning Inventory for information on using barcode scanners with myTurn.
Please note that you can also use RFID scanners to work with "chipped" badges, fobs, or other electronic IDs.
Anywhere you can enter a user ID, you can use a barcode (also bar code) of RFID scanner to scan the ID. Just tap or click in the field on myTurn and scan the ID. The scanner will essentially enter the code and submit the entry for you.
