• transmit an altering command to the altering module when the identification module successfully identifies the product code on the chosen product and the analysis processing module determines that the chosen product carries a tag;
• allow the user to reduce the number of the chosen product carrying altered tag through an interactive interface of the self-service shopping system or store staff when the identification module successfully identifies again the product code on the chosen product carrying the altered tag;
• and
• the altering module is configured to alter the tag on the chosen product based on the altering command of the analysis processing module.

A method for operating a self-service shopping system, comprising:

• receiving identification data of a product code on a chosen product;
• determining whether the chosen product carries a tag;
• if the identification data of the product code on the chosen product is received and the chosen product is determined to carry a tag, sending an altering command to alter the tag on the chosen product;
• and
• when the identification data of the product code on the chosen product carrying altered tag is received again, sending an unlocking command to a upper communication module to allow a user to reduce the number of the chosen product carrying the altered tag through an interactive interface of the self-service shopping system or store staff.
