A souvenir vending machine that handles the tax-free procedures for foreign tourists without a human has been installed on a trial basis at Nijo Castle in Nakagyo Ward, Kyoto City. Using AI (artificial intelligence), it can support 64 languages ​​and also uses facial recognition to verify the purchaser. It is likely to attract attention as a measure to address the labor shortage in the tourism industry and as a way to sell high-priced items.
