Let me just correct my previous testimony. The entity that has not signed on to the payment card code does not issue credit cards. Hence, there are no criteria that would cause them to sign on to the code.
My apologies, I had not recalled the fact as to why they were out. They actually wouldn't qualify to be a signatory because they do not issue credit cards in the way that Mastercard, Visa and others that have signed the code do.
I apologize for that error. Hopefully that clarification helps with your question.
