In 1970 John Esserian demonstrated a working bar-code system. See: various puiblication references in: http://www.aidc100.org/files/Memoirs-Esserian.pdf For historical completeness I should think Esserian's development should be mentioned in this article.

Why exactly do we care if the first article scanned was a packet of chewing gum, a car's half-axle, or a shipment of cocaine? Not to mention the purported name of the clerk and the time of the day. Sounds like completely useless trivia to me, however it appears three times in the article. — Preceding unsigned comment added by 18.104.22.168 (talk) 18:07, 23 March 2014 (UTC)
I do care enough to be happy that the information appears once, and to have the names of those who did it: it personalises a moment in history, and I'm glad of that. But, yes, more than once would be overkill. AdventurousMe (talk) 00:36, 10 June 2014 (UTC)
666 Outrage - Date?
This smacks very much of an internet-era moral outrage -- can we find any solid contemporary evidence of this controversy dating back to the early days of the bar code? Eg: a news report from a bona fide newspaper / a pastor's sermon in his local mag / etc. AdventurousMe (talk) 00:38, 10 June 2014 (UTC)
Barcode history - Barcodes were introduced in the UK by J Sainsbury in 1971, well before the UPC came into being. In an article in the Sainsbury house journal of August 1972 an article describes the system which by then had been implemented in about one hundred stores and was being extended into all 250. This happened over the following two years and the system was a resounding success. A derivative is still current (2015). The hardware was supplied by the Plessey company, and was originally a reading pen, keyboard and a tape recording device, housed in a trolley. It was powered by two lead-acid batteries. Further developments followed, firstly a shoulder-bag unit, then a hand-held unit as battery technology improved. The system software was developed by Sainsbury staff. The system was used by supermarket staff to place orders for the commodities, identified by the bar code. The units were called up by the central computer and the data was transmitted, processed and the resulting picking lists were transmitted to the distribution depots. This all happened at the end of the day's trading. The assembly and distribution of goods took place overnight with delivery the next morning. It was one of the first 'Just-in-time' systems. More than a million bar codes were read every week without any known errors. A cyclic redundancy check and a modulus eleven check number made the code reading virtually infallible.
