Apple Pay has been getting a lot of attention, and I hope to do a longer post on it, but for now let me highlight one possible issue that does not seem to have gotten any attention. I think Apple may have just become a regulated financial institution, unwittingly. Basically, I think Apple is now a "service provider" for purposes of the Consumer Financial Protection Act, which means Apple is subject to CFPB examination and UDAAP.
Here's the argument. Be warned: this is a romp through some legal definitions.
