How Debit Card Transactions Work at jjwin99
When you choose debit card on the deposit screen, you enter your 16-digit card number, expiry, and CVV. Your bank then sends a one-time password to your registered mobile number — confirm it and the amount moves to your account wallet. Most Pakistani bank cards route through 3D Secure, so that OTP step is standard, not optional. Withdrawal back to the same
card follows the same verification path: your card details are confirmed against the ones on file, and your bank processes the return to the original account. Availability depends on your issuing bank and local law.
