daptable currency and should use what is already ubiquitous, because it's too expensive to educate a market.

I agree totally. However to expand BTC beyond computer-to-computer use we need a POS-system.

Given this, the nature of BTC and your argument the technology that exists IS smart cards.

I don't think a swipe card can be programmed unless it has the same chip as a smart card anyway - otherwise I would be with you there.

Paper BTC won't work as you would have to trust a million different printers who could have saved the private key they put on the coin.
(Even Casasciuos has admitted this flaw)

Smart cards work very much like swipe cards though; the ONLY exception is that you insert it instead of swiping - PIN, terminal etc. all looks and acts the same.

You ignore the returned checksum unless merchants start scamming people.

The cards cost 2$ a piece so you could practically hand them out.

The terminal could be a 10$ cable, a free app and your already-owned android phone. A total cost of maybe 110$ that even grandmas could pay to with their card.

All WE have to do is to order the cards, cable (I'm sure it exists), develop the chip program and the android terminal client.

Then we release all our code, suppliers, data and guides and anyone can sell programmed cards in their region and anyone can download the app/buy the cable.

EDIT:
EXACT supplies needed to turn my Android into a POS terminal:

So... lets start programming?
