Taking real time payments via Bitcoin is just about impossible, as anyone versed in the cryptocurrency will know, due to the 'confirmation' times, which can often be up to half an hour. Which means that any POS (Point Of Sale) solutions need some kind of middle man that uses an escrow system backed by traditional financial arrangements. But with this caveat, POS systems for Bitcoin do exist - and now you can operate one such using nothing more than a tab in your Edge browser, thanks to Block!, a new PWA (Progressive Web Application).

From the Appscope listing:

Block! is a simple and powerful POS app for Bitcoin. Link your existing Bitcoin address and manage requests as easy as 1,2,3.

The URL to tap on or type in is project.blockpos.io .

Of course, you can turn this into an 'app' yourself with PAWA or just pin it 'as is' on your Start screen. It's up to you. If you're confused by the different PWA options then check out my feature here.

Here's Block! PWA in action:

Setting up a POS, you'll need a Bitcoin address for eventual receipt of crypto, plus a Wirex account for getting money out, I think; (right) accepting crypto is as easy as tapping in the amount in (here) Euros and tapping 'Charge'...

...the chargee is then shown a QR code, to which they can pay the appropriate amount in Bitcoin. This is the Escrow account, you don't get the crypto until half an hour later (or more); Block! is quite a polished PWA, with login and hamburger menu (including transaction history), and it works well in Edge under Windows 10 Mobile.

With the transaction delays for Bitcoin, real time crypto POS usually turn to 'Bitcoin Cash' or even the futuristic Ripple. But more on them in the future, I suspect. In the meantime hybrid solutions like this may well suit your needs.
