If the battery of your card reader is dead, you can replace it with a commercial coin-cell battery (CR 2025). Ensure that your card reader uses this specific type of battery, as some card readers use other battery types.
If replacing the battery does not work, use the free UBS Access App on your smartphone to log in to UBS Digital Banking and to confirm new payees. There is then no need to order a new card reader. Access App activation If you do not have a smartphone, you can order a card reader for a fee by calling Digital Banking support at 0848 848 064.
