Abstract: Techniques for providing a method of barcode-based mobile payment are described. One example method includes data indicative of a barcode is received from a barcode device in response to the barcode device scanning the barcode on a first client device requesting a service. Authentication information is determined from the received data indicative of the barcode that indicates whether the first client device corresponds to an account; in response to determining that the first client device corresponds to the account from the authentication information. An account limit is determined for the first client device from the account. A service requested amount is determined in the authentication information from the first client device and does not exceed the account limit. In response to determining the service requested amount does not exceed the account limit, data indicative of an acceptance of the requested service is transmitted to the first client device.
