A client contacted us regarding some inconsistent displays of the credit card number in his back end: sometimes, it displays 5424 xxxx xxxx xxxx 1234, sometimes it displays (last4)1234.
We don't understand how this happens. Appears to be random, and the (last 4 situation is particularly annoying, since only the middle digits are sent to the admin: he cannot see the fist four.
Any feedback on this (besides "don't use this module it's not safe") would be greatly appreciated.)
Thanks!
