Creativity and security

Blanking out all but the last 4 digits is foolish.  The last is a checksum
and the first four are determined by the merchant.  This greatly reduces
the possibilities for the other 8 digits.  I'd rather just Bank Name or even
the first 4 digits.  (I know that amex use only 15, even worse.)
