[quote="meltus"]it would probably be best if you have some code that detects that it is unknown and then tells the user to double check the number before proceeding.  The reason for the CC checking in the first place is to stop people accidently putting in an invalid number and causing your shop added time by having to contact the customer for the corrected number.


My point being - you are going to get a lot more mistyped credit cards getting through.[/quote]

No we aren't.

All I changed was the credit card identifyers.  Nothing in the MOD 10 checksum has changed, and if you put in an invalid CC number, it will still give the OSC "invalid cc number" error.
