As far as I know US banks use the same chip standard as European banks (EMV) and in some countries those transactions are pretty fast (in others less so). The card swipe doesn't use the same reader hardware as the chip reading (well, it is in the device) and there is more processing going on with more round trips to the bank if using the chip. Likely different parts of the software are used both at the reader and the bank as well. |
