CUSTOMER TERMINAL AND SELF-SHOPPING SYSTEM

摘要

A customer terminal of a “self-scanning shopping” system, which is configured to store at least one shopping session in a non volatile memory, includes a main processor, a product code reader, a location for non volatile storage of an open shopping session indicator and/or an identifier, either direct or indirect, of a shopping session, and a supervisor circuit. In a working operating state, the main processor periodically sends a heartbeat to the supervisor circuit. The supervisor circuit commands a reset of the main processor when, from the lack of receipt of the heartbeat, it detects a non working operating state of the main processor. The main processor, upon reset, checks whether there is an open shopping session based on the contents of said memory location and in the affirmative case restores said shopping session.

主权项

1. A customer terminal of a self-scanning shopping system, the system being configured to store at least one shopping session in a non volatile memory, the customer terminal comprising:
a main processor; a product code reader; a location for non volatile storage of an open shopping session indicator and/or an identifier, either direct or indirect, of a shopping session; and a supervisor circuit, wherein in a working operating state, the main processor is configured to periodically send a heartbeat to the supervisor circuit, wherein the supervisor circuit is configured to command an automatic reset of the main processor when, from the lack of receipt of the heartbeat, it detects a non working operating state of the main processor, and the main processor is configured, upon reset, to check whether there is an open shopping session based on the contents of said memory location, and in the affirmative case to automatically restore said shopping session.
