Latest Patents

Tajima holds a patent for a user authentication system. This system involves a card issuer visually confirming that a person requesting a user card is an adult. The card issuer then issues a user card with unique data recorded on it. The user writes personal information on the card, which is then inserted into a card reading section. An apparatus for identifying minors processes the unique data to output an identification number, which the user memorizes as a code number. When purchasing a product, the user inserts the card and inputs the code number. If the identification number matches the input code number, the system outputs a sale permission signal. This innovative design enhances security and prevents the transfer of authentication cards to others while effectively identifying minors in vending machines for alcoholic beverages.
