Shameless plug, If anyone’s building one of these cards, I made a wallet microservice (https://github.com/sudhirj/notecase https://github.com/sudhirj/notecase) for a movie ticket site I work on (justickets.in) It’ll let you track recharges, spends and balances for your customers, we use it for nearly a million customers.
