Title:
UNPOWERED SMART VENDING MACHINE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/149786
Kind Code:
A1
Abstract:
The present invention relates to an unpowered smart vending machine system comprising: a vending machine having secret keys stored therein so as to generate one time passwords (OTP) such that products are dispensed after verifying buyers on the basis of an OTP for product dispensing entered by a buyer and an OTP based on a hash-based message authentication code (HMAC) obtained by combining the stored secret keys; a buyer terminal configured to connect to a server device by executing a smart automatic vending application such that a product to buy is selected, a payment is made therefor, and generation of an OTP for product dispensing is requested; and a server device having secret keys stored therein so as to generate one time passwords (OTP), the server device being connected to the buyer terminal so as to generate and provide an OTP for product dispensing, including a watch (RTC), in response to a request of the buyer terminal, and the server device managing the sale and stockpile of products dispensed through the vending machine on the basis of payment information. The OTP for product dispensing includes a first OTP for determining the position of a personal identification code for identifying a product buyer of the vending machine, and a second OTP including a personal identification code for sale verification. The system advantageously reduces the risk of pattern exposure through existing reverse engineering analysis.
