The commercial use of barcodes began 45 years ago last week, and RxTrace began 10 years ago this week.  These are pretty incredible milestones and it is worth stepping back and thinking about what it all means.  GS1 issued a press release about the barcode’s 45^th anniversary last week, providing links to several videos.  These include some old-timey videos of what grocery checkout was like before barcodes, and when the UPC barcode was first introduced in Troy, Ohio in 1973.  It made me feel old.
