Abstract
Embodiments described herein provide a client system for facilitating enhanced offline payment. During operation, the system obtains a location indicator, which indicates the location of a service, from a charging system. The system then generates an offline code that allows access to the service and corresponds to the location indicator. The offline code can be readable by the charging system, and the client system and the charging system can both be offline. Subsequently, the system encodes the historical data associated with the service in a field of the offline code and sends a message comprising the offline code to the charging system.
