I don't see a problem with accepting a test credit card. Once your free trial is over, then they'll email you a message saying your card can't be charged and you'll be expected to update it.
- alberth2 15y agoNo, this is a major bug because they are trying to authenticate the credit card before accepting the input in the form field. Meaning, if you type "1234567891234567" that won't work, yet a test credit card # does work.
- m0nastic 15y agoThis isn't a bug. The validation that they are doing when you enter the card is just Luhn validation.§ This is basically just to ensure that the numbers entered into the field "at least have the possibility of being a valid credit card". No processing of the card is being done at this stage. § - http://en.wikipedia.org/wiki/Luhn_algorithm http://en.wikipedia.org/wiki/Luhn_algorithm
- joevandyk 15y agoThey aren't authenticating the card. They are doing a checksum on the digits entered using the luhn algorithm.
- functionform 15y agoExactly, its not a bug, its a feature. Just like mass assignment.
