The service is not all that different from a similar effort by PayPal, whose PayPal My Cash Card lets you add funds to your online PayPal account, using cash from your wallet. It also has a barcode-only service, powered by Green Dot. Walmart, too, has a Pay with Cash option. Interesting to see the different solutions helping people without a card/or preference for cash make it digital....and some AML/KYC issues coming with it
