I know this pay button seems like simple stuff, but I like to think we've done it next-level style:
- Crypto only but you can price in fiat (USD, etc)
- Super private: our payment flow (hate that word) works over Tor with Javascript and Cookies disabled (Tor browser's highest setting). [although you can't collect email/refund addresses in that mode]
The author here... I put this together right after I realized I could use it on so many of my different on-going projects. Of course geolocation is never perfect, but it adds lots of personality to a site to be able to list where people are coming from. Now with CORS support, means I can use this bit of infrastructure on all sorts of different browser-side JS projects.
Program's author here: the point of this app is to simplify the test and debug of the QR code itself. Although all reasonable people think they are pointless, countless graphic designers are forced to incorporate QR codes into their otherwise beautiful works. This app (and it's just an app, not an application) lets them quickly test variations.
It's busy, with crazy-lots of sliding images... but we've optimized the images and product-focused pages are supposed to packed with activity (I'm told).
