Traffic section fee payment method, fee system, and payment system

A computer-implemented method for traffic section fee payment, comprising:

• scanning, by an inbound charging apparatus, first barcode information displayed by a client device, wherein the first barcode information comprises first electronic credential information and an inbound timestamp, and wherein the inbound timestamp is added to the first barcode information and limits validity of the first barcode information to a predetermined period of time;
• obtaining, by the inbound charging apparatus and from the first barcode information, the first electronic credential information, wherein the first electronic credential information is a first authentication information generated by a payment system based on a user identity in the client device;
• sending, by the inbound charging apparatus, inbound information to the payment system, wherein the inbound information comprises inbound station information and the first electronic credential information;
• obtaining, by an outbound charging apparatus, second electronic credential information of the client device, wherein the second electronic credential information is a second authentication information different from the first authentication information, the second authentication information being generated by the payment system based on the user identity in the client device;
• and
• sending, by the outbound charging apparatus, outbound information to the payment system, wherein the outbound information comprises outbound station information and the second electronic credential information, wherein the outbound information and the inbound information are used by the payment system to determine a payment account that corresponds to the user identity in the client device and pay a traffic fee.

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• scanning, by an inbound charging apparatus, first barcode information displayed by a client device, wherein the first barcode information comprises first electronic credential information and an inbound timestamp, and wherein the inbound timestamp is added to the first barcode information and limits validity of the first barcode information to a predetermined period of time;
• obtaining, by the inbound charging apparatus and from the first barcode information, the first electronic credential information, wherein the first electronic credential information is a first authentication information generated by a payment system based on a user identity in the client device;
• sending, by the inbound charging apparatus, inbound information to the payment system, wherein the inbound information comprises inbound station information and the first electronic credential information;
• obtaining, by an outbound charging apparatus, second electronic credential information of the client device, wherein the second electronic credential information is a second authentication information different from the first authentication information, the second authentication information being generated by the payment system based on the user identity in the client device;
• and
• sending, by the outbound charging apparatus, outbound information to the payment system, wherein the outbound information comprises outbound station information and the second electronic credential information, wherein the outbound information and the inbound information are used by the payment system to determine a payment account that corresponds to the user identity in the client device and pay a traffic fee.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• scanning, by an inbound charging apparatus, first barcode information displayed by a client device, wherein the first barcode information comprises first electronic credential information and an inbound timestamp, and wherein the inbound timestamp is added to the first barcode information and limits validity of the first barcode information to a predetermined period of time;
• obtaining, by the inbound charging apparatus and from the first barcode information, the first electronic credential information, wherein the first electronic credential information is a first authentication information generated by a payment system based on a user identity in the client device;
• sending, by the inbound charging apparatus, inbound information to the payment system, wherein the inbound information comprises inbound station information and the first electronic credential information;
• obtaining, by an outbound charging apparatus, second electronic credential information of the client device, wherein the second electronic credential information is a second authentication information different from the first authentication information, the second authentication information being generated by the payment system based on the user identity in the client device;
• and
• sending, by the outbound charging apparatus, outbound information to the payment system, wherein the outbound information comprises outbound station information and the second electronic credential information, wherein the outbound information and the inbound information are used by the payment system to determine a payment account that corresponds to the user identity in the client device and pay a traffic fee.
