QR Code: History, Development, and Usage

In the 1960s, Japan experienced rapid economic growth. Supermarkets began expanding their product range from food items to clothing and other commodities.

Before barcode technology, cashiers manually entered each item into the system, which was very time-consuming. As queues grew longer, Point of Sale (POS) technology was developed. POS allowed items to be individually scanned and recorded in a computer system.
