Definition
A retail barcode is a graphical representation of data that is widely used in retail settings for product identification, inventory management, and point-of-sale transactions. Barcodes typically consist of a sequence of parallel lines and spaces of varying widths that correspond to digits or other symbols.
Historical Context
Barcodes revolutionized retail when they were first introduced in the 1970s. The first commercial implementation was in 1974 when a pack of Wrigley’s chewing gum became the first product scanned at a checkout in Troy, Ohio.
Types/Categories
1. UPC (Universal Product Code)
- Commonly used in North America.
- Composed of 12 numerical digits.
2. EAN (European Article Number)
- Predominantly used outside North America.
- Consists of 13 digits.
3. QR Code (Quick Response Code)
- Two-dimensional barcode with high data storage capacity.
- Can store various types of data, including URLs, text, and more.
Key Events
- 1974: First retail barcode scanned on a pack of Wrigley’s chewing gum.
- 1980s: Widespread adoption of barcodes in retail and manufacturing.
- 2000s: Introduction of 2D barcodes like QR codes for broader applications.
Detailed Explanations
Working Principle
A barcode scanner reads the information encoded in a barcode. The scanner emits a light beam that reflects off the barcode image, and a sensor detects the pattern of reflected light. This pattern is then converted into an electrical signal, which is processed by a computer to retrieve the encoded information.
