I'm sure there's a few of you that have built websites with CC verification routines in place that use the MOD10 procedure.
Has anyone noticed that this procedure isn't working as well on new issue cards?
Just done a site myself for a customer, used my own CC to check and it failed. The CC itself is working perfectly, and since receiving a new card in November, there's been a few sites that have said my card is wrong even though I know it's right!
Just used the customers card (again, a new Mastercard issued to him in December 2007) and that too has failed the MOD10 but is a perfectly valid card.
Anyone know if there's a new library to use or if this is a known problem?
