A great project and I like the idea. But I do not understand how the technology of decentralization will help here? Can you talk more about this?
Agree, with this query. Like how does blockchain come in as an advantage in this platform? Have you considered launching this even without blockchain?
Decentralization thanks to the blockchain (and a specific smart contract) is the key including for the real-time payment, the security and the traceability.
Such a service would be very difficult in the "old world"

Nice. Real-time payment is surely a unique selling proposition. Is there a list already of where the SnapCoins will be available?
