Hello everyone!
I was a bit surprised not to find any ready-to-use credit card number validation classes on GitHub made with Xojo… so I decided to create and share one!
It includes basic support for Visa, Mastercard, American Express… , and also includes simple validators for IBANs, etc…
If that’s something that might help you, feel free to check it out or improve it!
Link on Github : Xojo-Credit-Card-Validator
Hope it’s useful!
