We are internally testing xDAI in Progressbar, we are using it for paying up for food between each other, i.e. when we are in restaurant, when someone pays the bill by card, then taking photo of receipt and post it in internal group with their address.
As I have experience with Google Cloud Vision, would be interesting to parse receipts/bills from restaurants, generate payment requests and particular consumer of each item can click to pay thing so make it bit easier for processing.
Later on could be done maybe through smart contract or service which could be embedded in other wallets.
Any suggestions? Is there any similar service for Ethereum yet?
