[0017] [Figure 1] FIG. 1 is a diagram showing an example of a conventional tax exemption management process. [Figure 2] FIG. 2 is a diagram showing an example of the tax exemption management process in this embodiment. [Figure 3] FIG. 3 is a block diagram showing an example of the configuration of the tax exemption management system according to this embodiment. [Figure 4] FIG. 4 is a flowchart showing an example of the process of the tax exemption management system in this embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to this embodiment.

[0019] [1. Overview] First, an outline of the present invention will be described. Fig. 1 is a diagram showing an example of a conventional tax exemption management process. Fig. 2 is a diagram showing an example of a tax exemption management process in this embodiment.

[0020] As shown in Figure 1, traditionally, at tax-free registers, staff would check customers' passports, confirm whether the products were eligible for tax-free shopping, process the tax-free process, and deliver the consumables in special tax-free packaging. The sales details of the tax-free products were linked to the passport data and sent to the National Tax Agency's tax-free database (DB). Also, as shown in Figure 1, traditionally, at tax-free counters, staff would check customers' passports, confirm whether the products purchased at each sales counter that day were eligible for tax-free shopping, and after confirming whether they were eligible for tax-free shopping, calculate the consumption tax on the receipt, refund the applicable consumption tax, deliver the consumables in special tax-free packaging, and deliver the products in special tax-free packaging. The sales details of the tax-free products were linked to the passport data and sent to the National Tax Agency's tax-free DB. As a result, the National Tax Agency's tax-free DB previously accumulated detailed shopping data linked to the passport data handled at each tax-free store, allowing for the creation of a detailed list of what was purchased tax-free for each passport number, in what order, at which store, without the need to check items taken out of the country.

[0021] Therefore, as shown in Figure 2, in this embodiment, purchase detail data linked to the same passport as the data sent from the duty-free shop to the National Tax Agency database is received, and a database is constructed that accumulates data linking the purchase detail data of each person's tax-free purchases with the purchaser's passport data, similar to the database constructed by the National Tax Agency. Then, in this embodiment, the shopping detail data linked to the passport number of the item being purchased now is aggregated with the shopping data of already purchased duty-free items linked to the same passport number, and when checking the tax-free status of all tax-free purchases, if there are any items among the items being purchased now that are not eligible for tax-free exemption, a system is provided in which certain discount tickets (for example, a discount equal to the amount of consumption tax) are immediately issued for those tax-exempt items and can be used to pay for them.
