This [post](https://www.reddit.com/r/btc/comments/kw7z20/lowest_cost_pointofsale_system_ever_piece_of_paper/) on /r/btc got my mental gears going about the use of a fixed QR code as a

What I was thinking is that customers could come and scan the QR code, enter the

The Merchant's phone or custom computer setup will notify them when a new message/order comes through,

So a few additional thoughts.

1. A busy merchant can focus on fulfilling orders instead of processing payments. This cuts out a

2. A QR code could be tied to a specific area/table/chair that would aid in reducing error.
3. No lines for customers are needed to

| place orders. They simply scan and order, or even have the possibility to order in advance and pick up the order.

A downside to this proposal is that it allows anyone to see the
