[intron]

Made this, a small and low-cost btc payment device:




It has WiFi to connect to the internet and NFC to
communicate with a user with a mobile phone. It
can be used to handle small payments and to perform
a simple task when a payment is received. Cost price
can be well below USD 10.

Very neat.  If the board antenna +chip can be moved up, that would make for a tidy package to build a case around

The board measures 34x74 mm, think a case can be tidy enough:)

True - I was just thinking that because you need the vertical height for the bluetooth module anyway, one might as well stack, a la: https://i.imgur.com/gDrh7r4.png
Regardless, though - very neat   Just a design for now, or planning sales?

I see now. When the performance of the NFC antenna
is not degraded it could be done I guess.

And it's WiFi btw, not bluetooth:)

Just a proof of principle, playing around a bit:)

Gotcha - would be a neat little addition to ad-hoc point-of-sale terminals without the cost overhead of full-blown bank-sanctioned ones.

And it can do micropayments. Try paying half cent
for something using a normal terminal;)

Hi, this is really cool but.....

What can you actually get for half a cent nowadays?
In fact, can you actually get chewing gum with 50 cent nowadays?

Some juice to charge your mobile phone, or some
drinking water, or some air to inflate a tire etc:)

It could be a method of making really small
payments in the physical world.

Make it nine Euro cents then for a popsicle;)

[TheRealSteve]

rocket popsicle - yum.
If you go to places like Party City in the U.S., the individual candy stuff (like the chocolate coins) are still just a few cents/piece
( unless they've moved to selling by weight by now, which would be the sensible thing to do, though pricing would still apply )

Looks great wow! Makes a great way for the bigger audience to accept Bitcoin!
Imagine people walking in the streets with these in their pockets and phones in hand just sending and receiving money!
