In order to avoid any misunderstandings, I want to clarify that I’m not part of this proposal, neither got in touch with Daxby or know who he or she is, but I’ll be more than happy if the Spark Nimiq MVP were used as inspiration or even could be taken as a starting point for developing a more fleshed out Nimiq POS application. I’m also open to any collaborations for getting those POS apps out there to the public (be it Spark Nimiq or any other Nimiq POS app) so that people start actually using them in brick and mortar stores.
I can’t take credit for the idea either, since the Spark POS app is open source and it was originally developed for other coin. What happened is that I had the opportunity to use Spark for making payments with crypto, and then I discovered that it was open source. So, I thought it would be kind of cool (and relatively easier than developing something like that from scratch) if someone were to changed it to support Nimiq.
I also made a few improvements, like adding fiat price rates not originally supported by the app, and ported the app to Svelte, which is a lighter and faster framework. In theory the Spark Nimiq app should be more responsive, for instance when running on low end mobile devices.
