Over the weekend I noticed that my local McDonalds (in Minneapolis, MN) had installed a new type of reader next to the normal credit card terminal with NFC reader. It looks like some sort of Honeywell optical scanner. Anyone have any idea what it is for? Seems like it would be the sort of thing that CurrentC would require, but I haven't heard of McDonalds being part of their rollout. Are there other payment systems that would use this type of reader? All of the terminals at this restaurant had them installed.
