Description

  The present invention relates to a settlement system and a settlement method in which a user selects a transaction target at a plurality of providing locations, and the transaction targets selected by the user are settled together at the settlement location.

  2. Description of the Related Art Conventionally, there is known a collective payment method in which a user selects a transaction target at a plurality of providing locations, and the transaction targets selected by the user are settled together at the settlement location.

  The settlement in this collective settlement method includes a method in which an operator visually confirms at a settlement location after the user has selected a transaction target, and a method in which the transaction target is automatically identified and self-settled.

  In the case of self-settlement, a method for automatically identifying a transaction object by attaching a non-contact IC tag to a dish or the like on which a transaction object is placed in order to identify the transaction object, and placing a dish or the like on which a transaction object is placed on a non-contact tag reader device, There is a method of automatically identifying a transaction object from a camera image.

  In the former method using the non-contact tag reader device, it is necessary to attach a non-contact IC tag to all dishes and the like, and a non-contact tag reader device is required. There is a problem of hanging.

  The latter method using camera images also requires an image recognition device and requires complicated image processing, which also requires a large amount of system introduction cost.

  In addition, instead of a collective payment method, it is possible to use a payment method for each transaction location using an ID card or prepaid card held by the user. There is a problem that the amount of data becomes enormous and the amount of data to the host device increases.

  Here, as a conventional technique for solving the above-described problems, a recording unit capable of writing data is mounted on a tray on which a product is placed, and price information of the product is stored in the recording unit every time a user receives the product from the product display stand. There is known an automatic settlement system that performs a settlement process on a total amount of products on a tray by writing and reading price information recorded in a recording means at a settlement place (see Patent Document 1).
