Mask credit card number on manual entry

[hengwoon]

Is there an option to enable masking of credit card numbers (much like a password field) being entered via manual entry in the CardIOPaymentViewController?

@hengwoon, no, that is not currently an option.

We have considered this option, but our conclusion has been that it would add relatively little security for users, while making it much more difficult for users to confirm that they've entered the correct digits (a significant issue on error-prone phone keyboards).

If in your situation the security considerations outweigh the usability concerns, you can still use our CardIOView to handle card-scanning, while implementing manual entry in your own view controller.
