Long ago I said CurrentC would be DOA; after all given the alternatives of plastic and NFC, who would want to use a fiddley QR based system that gives a Walmart backed consortium access to your bank accounts with none of the protections or rewards offered by the CC companies.
I may have been wrong.
It looks increasingly likely that it will be stillborn.
If it's going to be anything like Target's "Debit" card I'll pass. The card can't see your available balance, and they take 3 days to ACH the money out with no post to your bank. If something goes wrong, they charge "bounced check" fees.... For an ELECTRONIC service. All the trouble of a checkbook with no built-in protections of Credit cards. It's utterly useless for "impulse" transactions if I have to wait 3+ days for the accounting to catch up. In contrast my Walmart prepaid debit card reconciles transactions in minutes so you're never going to "overdraw" it which is perfect for "penny" transactions like lunches and snacks.
