A Cloud-Based Smart Expiry System Using QR Code

In this paper, a novel cloud-based smart expiry system is proposed which sends an automatic notification to customer's smartphone several days before the purchased food expires. The checkout operator app in the store generates a table containing product names with expiry dates and it is uploaded to the cloud. The customer scans a single Quick Response (QR) code printed on the purchase receipt with a smartphone. The table is then downloaded from the cloud to the smartphone automatically and the customer is be all set to receive the expiry date reminders and notifications. Compared with other works, the proposed method does not need tedious manual entry of each product name and expiration date into the smartphone app, rather scanning a single QR code will be sufficient.
