Accepting Bitcoin in a Bricks and Mortar Shop

[Meuh6879]

I don't really understand how to do it.

1) buy a tablet (cheap, android)
2) install android bitcoin wallet (schildbach)
3) open
4) create a NIP and a password (to spend only ...)
5) make backup and store on safe place
6) install the tablet with charger on your desk
7) create a "bitcoin accepted here" screensaver ...

when a client ask for bitcoin :

8 ) open tablet
9) tap on "receive bitcoins"
10) tap the sum
11) QR-Code is displayed
12) client can use his smartphone to pay (it's the client that it pay tax, not you)

13) wait the 0-confirmation of the Bitcoin Network (6 seconds for example)

How do I add a business to coinmap.org?

1) go to OSM (OpenStreetMap) : http://www.openstreetmap.org/
2) on the right, tip on the "sticky" note (or bull icon).
3) move the sticky to your place
4) complet the sticky with "hello, it's my shop and i accept bitcoin, thank to add this !"
5) a member see this and draw the request.

I can't see any sticky note or bull icon.

But what if you can't afford an extra screen? (because moving your screen everytime to show the client would be extremely annoying). There should be a way to print a single public address, then people pay there but you get paid in a randomly generated new address that no one can know besides you. Isn't this what HD wallets like Electrum do? I have no idea how it works yet and would like to learn.
What you propose is not very convenient, there must be better ways to do this if we want mass adoption

That's an interesting idea. A QR code simply holds information, so I guess it could hold a public seed instead of a pubic key, but the customer's phone would still need to have software that recognized and generated the address to use.

Another option might be buying an extra monitor. Many laptops come with an external monitor port and you can buy flat screens on Amazon for as low as $10 used.

I believe any QR code reader on the phone can easily decrypt the info. Lots of apps in appstore to do so. If the software used by customer can't use the format, the user can easily copy the address and send it manually. Any tablet is capable of displaying a merchant app or Qr code.
