I apologize, but I still don't get it. Basically, this would allow someone to build software that physically can process credit cards? So basically, this is for companies that sell point of sale systems? I am aware that credit card processing is quite poorly implemented, so it seems like they are: * making it less bad * further exercising their monopoly * adding more security at the transmission level so, like who would use this? Basically this is for something like square where you would actual take physical cards and process them? It seems like if a user has a debit card you can process a fee for like 5 basis points. So, Visa is offering a way for merchants and payment processors to improve the security of their (credit card companies) own product so feasibly, they could lower their fees in the future, because they wouldn't have to pass along the massive amount of costs fraud creates due to the systems insecurity. So, like, who uses this? Just payment processors and companies big enough to have their own point of sale? It seems like a big bet to expend engineering resources on. What is the upside? Security is priced in to the processing fee, right? So, basically there is no gain for someone who already has a working gateway unless they force them to use this. If you do that engineering spend and get it to work, it is a big bet that users will continue to use a fairly unsecured payment method and carry it around with them, and that mobile payments won't become normalized in the next few years.
