Awesome!

Not the girls; BitPay!

edit:  you gotta stop torturing us like this 

We accept the payment right away, but alert the merchant immediately if it becomes invalid.  We haven't seen one yet, but for such small dollar amounts, we don't foresee it being an issue.  The merchant always has the choice to wait a little longer for more confirmations.

From what we can tell, merchants probably have a higher risk of getting a stolen credit card than getting a double-spend of a bitcoin.

I think its a little early to make that statement. 

Some people like grandmas might be intimidated by the QR Code and camera concept.  Have you guys looked into http://bu.mp?

The comparison with PayPal is entirely relevant: here we have a massive company with 100 million of active customers and 70 billion annual turnover. They could easily build a mobile application that enables the bar to accept euros or yens from the user's PayPal account. Such an application would be thousands of times more interesting to the bar than Bit-Pay mobile, since thousands times more people have non-zero PayPal accounts than bitcoin balances. Yet what does PayPal do ? They issue their own credit card - they want a piece of the credit card action ! That's because even for PayPal the network effect is too faint for retailers to bother implementing their system.

Online and e-commerce is where ecurrency works. If it succeeds there, maybe, just maybe there's a chance in the retail world, but this product does not have, at the moment, any place in the market.

As for credit cards going away, let's not get ahead of ourselves. The physical aspect changed from carbon copy to magstripe to chip and now to NFC. But the same old credit card cartel gets to steal 3% of your purchase, represented by MasterCard in the case of Google Wallet.

Bitcoin will do to the banking cartel what email did to the post office, and what internet did to newspapers, then travel agents, then media companies.  It will cannibalize their fees and profits and they either need to adapt or die.  It may not really take off for another year or two, but that's fine.  That gives us more time to write more software and fill out our product line.  And make more videos with the Bit-Pay Babes.

It's a little bit extra work, but it isn't expensive to prepare thousands or hundreds of thousands. Use SendMany to do a few thousand at a time sending 1 satoshi. Someone was even saying that you can prepare to have addresses with 0 output, but it hardly matters.

Maybe this is anti social behavior though since those get logged forever.

This system is very easy to use.

It is implemented at my wife's boutique in Tarpon Springs, FL.

Hopefully I can get enough merchants interested to the point that you can take a Bitcoin vacation in Tarpon Springs.

I'm looking forward to the day I can fly to Tokyo, Dubai, and all over the world, and NEVER have to change my money every time I get off the plane.  Just load up bitcoins on my phone, and go.

The advantage of not having fees does not materialize for the client, so he's unlikely to care that the shop is saving money. The customer drives the demand for a payment method - the shops are forced to follow or loose market share. The shops would get rid of credit cards in a hart beat if they could get the customers to pay with cash.

So aside of the phony geek appeal, what does this system offer to the customer ? Credit cards offer interest free loans for up to 2 months, emergency funding past that period, and money back guarantee. Bitcoin offers final indisputable transactions  - why do you think customers will prefer it ? Don't even get me started on the clunky desktop client that kills your harddrive.
