Determining Credit Card vs. Debit or Check Card

Bill D'Innocenzo

There are many functions available that implement credit card identification
and number validation -- meaning you can decide, based on the number, if a
card is a MasterCard or Visa and if the number passes the Luhn Formula or
MOD 10 algorithm for the checksum. What I'm looking for however is the
scheme to determine is a card is a check or debit card versus a credit card.

Anyone know if this can be done by examining the account number pattern?

Thanks,

-Bill

I have been doing that since 1990
- but have delegated the responsibility to the clients

There are rules, there is even some sort of primary validation system,
but there is a lot to be said for a visual reprensation

credit card validation routine

by: dries | last post by:

A friend of mine has a problem with his credit card validation routine and it is probably a simple thing to solve but I cannot find it. It has to do with the expiry dates. What happens is that as each month passes, that month is then not recognised as being valid, even though the year makes it still valid. i.e. the number of the month entered has to be bigger than the number of the current month. Therefor, if it is in august now 09/2005...

credit card transactions

by: anna cypher | last post by:

I am considering taking on a project that requires the app to charge credit / debit cards. I have no idea how to do this... I'm sure buying the actual reader and getting it to work with an app would be easy enough, but what about performing the transactions themselves? Perhaps there's a library I can purchase that does all this pretty much automagically? Can anyone point me to some good resources? Anna

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
