If no, reverts/doesnt go through * If yes, smart contract finds the wallet address mapped to debit card number. * Smart contract transfers token amount from debit card wallet address 1 to debit card wallet address 2. *** RESOURCES Create Visa Direct business wallet given debit card number\ Prefund Visa Direct business wallet with Visa’s custom stablecoin\ XFT TOKEN SERVICE ABI
