Problems solved by technology

[0009] However, the problem with this tax refund procedure is that the tax refund merchants transfer the data that needs to be provided to the National Tax Service and collect handling fees as they handle the sales, tax refund, and settlement of duty-free shops after the event.
That is, the tax refund merchant provides a part of the tax refund (α) as a rebate to the after-sales duty-free shop, resulting in a contradictory result that the after-sales duty-free shop (α) + tax refund merchant (β) defrauds 2.5% of the national tax
As a result, the discount effect is also reduced, so there is a problem that it does not meet the purpose of the original system
