I created a GitHub repository at https://github.com/Marc26z/ZapShirts. Here is a copy of the README.md

ZapShirts

This is an idea I have to make t-shirts that are also bitcoin point-of-sale terminals.

Create T-Shirt Point-Of-Sale

The idea is to create a bitcoin point of sale on a T-shirt. You can use it to sell stickers at a conference or have a friend pay you back for dinner. It is only limited by your imagination.

Why Would Anybody Need A ZapShirt?

I no longer "orange pill" local businesses. I do not care if they wish to accept bitcoin, but I want to be the change in the world I want to see. I will accept bitcoin on a T-Shirt to show others how easy it is to accept bitcoin as a p2p electronic cash system. Anyone can accept bitcoin as payment if they want to. You could print a sign on a piece of paper if you wanted to. The problem was, nobody I asked wanted a sign, even bitcoiners. So I asked myself...Self, what if you did the opposite? What if the customer accepted bitcoin, but the business owner did not.

I also thought it would be pretty cool T-Shirt to wear at meet-ups.

How To Make Your Own Zap Shirt

1. Create a QR code that sends you to your coinos page, getalby page, strike or whatever you feel comfortable using. This can easily be done at https://libreqr.com/
2. Use a program like gimp to replace the default QR Code with your own QR code on the file.
3. Create the shirt.

To support this please zap me or buy one from my store.

I like the idea of open sourcing my ideas and trying to sell them for sats on the Internet. I am currently working on a site to sell things like this and my gift cards. I feel a little uneasy because I haven't been writing much, but I've been building. The idea is to create bitcoin educational products and services.
Onward.
