That seems likely, but I don't have evidence either way. In one case the transaction came through as what I presume was the driver's name, the other as "SQ *TAXI OF CHICAGO".

Still, the that fact that out of three recent cab rides, the two trips involving credit cards were both paid for using Square is an impressive sign.

As noted by others in this thread, drivers here regularly try to use the "machine is broken" tactic, despite the law. If Square's existence makes taking credit cards sufficiently easier for drivers then cab riders will directly benefit.
