Other Significant Bar Code Mandates

1983/4

US DOD US Automobile Industry

These mandates together with UPC and EAN sharply accelerated market growth.

Subsequent Progress

Bar code replaced OCR in fashion retail

International Symbology Standards Verification developed & standardized 2 dimensional bar codes Ultimately bar code spread world

wide to every facet of retail, distribution, and manufacturing

RFID – my opinion

RFID will take root and flourish, not by replacing bar code, but by solving those problems wherein it provides the superior solution.
