"...retail customer's money is on the line in the event of fraud..." is a good point that may just slide by. The fact that corporations have significantly moved to evading any kind of responsibility through various means from regulatory capture to force arbitration and market monopoly; it strikes me that the factor of risk to the retail consumer aspect will play a huge role. It is a huge competitive disadvantage, to both not develop something well and with vigilance towards security like Apple Pay is, while also then setting in place a framework for conveying to customers that "if there is fraud because of our poorly designed and developed system, we are going to duck and weave like champions". Do you want to keep away customers, i.e., revenue, because that's how you keep away customers.
