2. No restaurant near me has remote pay terminals, not a single one. My pizza delivery guy does not have one, either. Orders have to be paid for with a card at at time of order and the delivery guy just brings the receipt to get a signature.
That will soon change with EMV chip cards coming to the US as it means any type of card could need a PIN (Credit or debit) (Although the majority of US Visa/MC/Amex issuers will be doing chip and signature, international visitors, Discover cards and some US cards will need a PIN), which means generally restaurants will have to bring the machine to your table or you will have to get up and pay anyway.
On the flip side, the main flaw with this is that this won't work with the chip cards as the magnetic stripe on a chip card has a code on it which says (Only allow a swipe if the terminal doesn't support chip cards). So by October 2015 this will be defunct and NFC mobile payments will be widely accepted like they are here in the UK and Australia as pretty much all new chip terminals support contactless.

I don't know what effect chip & pin will have on this. I assume when that becomes big, both (if they still exist) will integrate a chip into their systems to work with this standard.
This device won't be compatible with chip and pin cards at all. You can't clone and re-transmit chip card data (Thats kind of the whole point of chip cards), so it will be impossible anything like this work. NFC is really the only EMV (Chip card standard) compliant option.

When you say chip and pin, I assume you mean EMV. That would be the same technology that came out 15 years ago that is still at 5% acceptance in the US, and all EMV cards still have a mag stripe. As the EMV card still has a mag stripe it is still subject to skimming by scanning devices. Sorry, but I don't see millions of POS devices being changed out by next year. Hasn't happened in 15 years, and isn't going to happen next year. Same or better security with acceptance by merchants.
You would surprised at how many terminals in the US are already chip card enabled. Just look for
the slot. While most of the slots aren't yet enabled (Even my international EMV cards are still swiped) some are (Some Walmarts and many small businesses that use chase payment tech) and most can enabled via a software update (Usually remote).
Also bare in mind that you can't use the magnetic stripe off a chip card on a terminal that accepts chip cards, so that could quite easily cause issues with this device once your card has been replaced.
The only real way this could succeed is if they partner with banks and banks issue virtual magnetic stripe data card to be used.
