Modulus checking subscription

Liberty Create - Build Advice

Hi,

We are investigating setting up a system a few area’s but wondered if anyone has had any experience in utilising either via APi or flat file the modulus checking subscription?

This would be of use for anything where we ask for banking details but specifically right not the national Council tax refund that has come out of the woodwork.

Thanks in advance
Joe

Afternoon Joe,

I have written a few such modulus checking functions before, including the Luhn Algorithm as used in Credit Cards.

If you have a specification, I would be happy to look at assisting you in creating a fragment validator or Event Action to do the necessary checks.

I would however advise that credit card details should never be stored in their entirety within Create as this would bring the solution within the remit of PCI DSS (Payment Card Industry Data Security Standard).
