Although I now live in a neighborhood where food stamp use is probably not common, I was recently behind a user. (Did not survey her order!) It seems to be more like a debit card and couldn't be used in the regular way in the device at the checkout for bank credit and debit cards,; it was the exchange between the clerk and customer that let me know what it was.
