MANAGING AUTHORIZATION CODES FROM MULITPLE SOURCES

摘要

The present disclosure describes apparatus, systems and methods in which a first data storage is maintained for a first group of authorization codes, for example those associated with a local POS system, and second data storage, logically separate from the first data storage, is maintained for a second group of authorization codes, such as those associated with a remote or online sales system. Access control is achieved by checking a received authorization code for validity against one or both groups of authorization codes, without needing to integrate different code assignment systems or different sales systems with one another. The technology has particular utility for automated car wash systems, although it is not limited thereto, and embodiments of the technology may be retrofit to existing car wash control interfaces.
