Ann: ISXPay - Mastercard Principal Membership, page-4

My read of it was that ISX is now on the list of approved MasterCard partners. This means that merchants can sign up with ISX through MasterCard and the KYC/AML/Identity technology will be seamlessly integrated.

That opens this technology up to all merchants globally, and even though transaction fees may be small, the volume of transactions will be enormous. All good in my opinion..
