There's quite a lot of scam potential here, not implying that you are a scammer, but that if your app does ever make it big, you can bet that there are going to be making apps similar to yours, or even impersonating your APP and then sending our wrong QR payments/addresses that instantly redirect to their own personal address.
It definitely sounds festive and right in the spirit for the holidays, but unfortunately, there are terrible people out in the world and QR codes just end up becoming scams when you see the number of fake QR scanners out on the play store nowadays.
Its not an app, its just a greeting card and a QR code is printed there that they can scan. Its just an idea, I don't have any knowledge of how to build or create an app. Maybe I'll use an existing platform and use their services for this idea. Probably the downside there is they need to download that app, app that is not mine or i'm not related to the owners.
Just imagine those physical Bitcoins that are being sold in the Collectibles section, some of those that are being sold are funded.
Ah, my apologies. So, I'm assuming that the greeting care would be different for each user and they'll basically be able to claim X amount of BTC from the QR code? Interesting.
There's actually no existing platform by the sound of it, it's definitely a unique idea and I doubt anyone has even thought of it before.
Having a faucet a system where you are rewarded with a small amount of BTC at the start, and then they are able to complete surveys, even use their phone for mining and watch ads for BTC. There definitely are apps like this, just not sure if they'd use BTC.
