I am not certain how secure the one time code is. It is better than no one time code.

If you don't trust one time codes, then you shouldn't trust chip card transactions, because the chip card protocols are all based on one time codes.


The question is if RFID skimmed information sufficient to associate the one time code.

The table top terminals at the restaurants here require a signature.

Even the ones that allow chip transactions, rather than mag strip swipes? The ones that only allow you to swipe still require signature. The ones that allow chip transactions (a recent change) don't require a signature.

Yes, I used a chip card yesterday at a table top terminal yesterday and it required a signature.
