>>The problem with a credit card is if they hack the card account they get enough information to open additional cards. If they hack the debit card account data they get the checking account and the pin which is much more limited.<<
That is quite a grandiose statement.
I suspect it is wrong in both assertions but I am sure you can provide some documentation...
No documentation. It’s based upon the assumption that credit card account information is more detailed than a debit card info which is fixed to a specific checking account and bank.
