There is a setting "Allow manual card numbers" on the card setup that will open the card number field for all the issue, redeem and balance check operations on the POS. Ideally, we'd be able to isolate these operations and only enable manual entry on redemptions and balance check, but not on issue. This would force store staff to use the MSR or scanner to issue the card (and prevent bad data), but would still allow them to redeem against the card later if the MSR/scanner is no longer able to read the card after some wear and tear.
