Hi,

With all the news about payments, I wanted one place to see the best articles. Hence, BasisPoints.

The site is run on telesc.pe, an open source Meteor project, much appreciation to the contributors.

Hi,

With all the talk of ApplePay and payments in general, I wanted a place to find all the best writing on the topic. Hence, BasisPoints.

I threw this up with much help from http://www.telesc.pe/, an open source hacker news clone built on Meteor.

Apple needs the networks and/or the banks to tokenize the CC numbers at the time the card is imported into the wallet.

When the payment is processed, that same network/bank takes the token provided, translates it back to a card number and passes the card number to the issuing bank.

I think it's actually quite a feat that Apple managed to tokenize all 800 million existing card numbers, because of this requirement.

Patrick,

Curious, was the majority of the work required to support ApplePay related to the format of the PKPayment? I assume in other cases, you just pass the raw PAN + pin, etc, where as now you need to pass the encrypted single use token + cryptographic data + more. Was more work required to support ApplePay?

And if so, did Visa/MC/Amex and the processing networks recently start supporting this payload, or has it been in place for some time?

Finally, what does Apple use the Merchant ID for?
