A method may include reading a barcode and decoding the barcode to obtain a refill code at a user device, receiving an identification number and the refill code from the user device, determining whether the refill code is valid, and determining whether the identification number is valid when the refill code is valid. In addition, the method may include, when the identification number is valid, initiating a payment transaction to refill a prepaid card account. Further, the method may include receiving a user confirmation of the payment transaction when the application is at the network address, and completing the payment transaction and refilling the prepaid account when the user input confirms the payment transaction.
