This is not a new product or product idea as there are many pos/nfc systems in use or production already.This product and its associated token are contingent to mass adotpion.If on release it offers updated features it may succeed.
I have to disagree, if I understand you correctly.
The success of TillBilly is not contingent on mass adoption of our PoS terminal, BILL tokens (directly), or even mass adoption of cryptocurrency. This is because at the core we are a general payment solution for both brick and mortar and online shops. We provide not only a cheaper alternative to traditional means of payment, but a currency agnostic one. So users can use fiat or hypothetically other stable, asset backed tokens on our platform (and alt coins of course). The reason why we can do this more efficiently is because we use blockchain, specifically Stellar, on our back end. All of the benefits of blockchain without the volatility or sluggishness of older chains like Bitcoin.
We are focused not on cryptocurrency enthusiasts, but on everyone.
If you want a good macro perspective on our vision I recommend reading this article I just wrote
