Abstract: A payment method, a payer terminal, and a payee terminal are provided. The method includes receiving a transaction request from a payee terminal that includes a payment amount and determining whether an electronic cash application has a balance that is sufficient to cover the payment amount. If the balance is not sufficient, determining whether there are at least two electronic cash applications, a sum of whose balances are greater than or equal to the payment amount. If the balances are sufficient, selecting a group of electronic cash applications, a sum of whose balances are greater than or equal to the payment amount, performing deduction from a balance of each selected electronic cash application until a sum of the deduction is equal to the payment amount; and sending account number and corresponding deduction data of each of the selected electronic cash applications and transaction identifications to the payee terminal.
