Four Decades On, Barcode Still Ruling Retail Businesses

On June 26, 1974, the first ever barcode was scanned as part of transaction. 43 years since then, today trillions of the codes, officially called Universal Product Code, exist worldwide.

 

“It was cheap and it was needed,” said George J. Laurer, who was an engineer at IBM who, in the 1970s, led a team looking at new checkout systems. “And it is reliable. Those three things probably contributed more than anything else,” he recalled.

 

It revolutionized the world of retail and despite many attempts to dethrone it, the barcode has reigned supreme ever since. The honour of scanning the first ever barcoded product went to 31-year-old Sharon Buchanan, a cashier at the Marsh supermarket in Troy, Ohio.

 

“I was a little bit nervous at the time,” she recalled in an interview with the New York Times.

“I mean what if this doesn’t work? Everybody was there taking pictures, the photographers, the local press, people from around town. But it worked just fine. It was quite my 15 minutes of fame, I suppose,” she added.

 

That first product was a pack of Wrigley’s Juicy Fruit chewing gum. The pack was gingerly passed over the scanner, the register went beep and 67c was rung up. In that moment, shopping changed forever.

 

Given a different set of circumstances, our barcodes may have looked very different. Rather than being the familiar monochrome fence we know today, sitting atop a row of digits, the bar code might have been a bull’s eye or a series of dots.

 

Norman Joseph Woodland, the man credited with being the inventor of the barcode favoured a circular shape and ended patenting just such a round code. From New Jersey, he had spent WWII working on the Manhattan Project — the top US secret plan to build the world’s first nuclear bomb.

When the war finished, he turned his head to more mundane matters. Matters that would, nonetheless, affect the everyday lives of far more people.

 

In 1948, Woodland’s friend Bernard Silver mentioned he had overhead a supermarket executive pondering if there was a way of recording automatically product information at the registers, and so speeding up the checkout queue.

 

An inventor by trade, Woodland, thought Morse code might have the answer with its series of dots and dashes to communicate information. His epiphany came on a Miami Beach.

 

“What I’m going to tell you sounds like a fairy tale. I poked my four fingers into the sand and for whatever reason, I didn’t know, I pulled my hand toward me and drew four lines,” he told Smithsonian magazine.

 

“I said: ‘Golly! Now I have four lines, and they could be wide lines and narrow lines instead of dots and dashes’. Then, only seconds later, I took my four fingers — they were still in the sand — and I swept them round into a circle.”

 

The idea may have been born but the development had only just begun. Myriad problems had to be overcome including the barcodes blurring due to the limitations of printing at the time and the sheer cost of scanners.

 

It was supermarket executive Alan Haberman who took Mr Woodland’s idea and, finally, in the 1970s made it a reality. He led the industry committee that got everyone to agree on one common standard for the code.

 

He also sifted through the various curves, dots and bullseyes and settled on straight lines as the preferred shape of the barcode. It took just five years for the barcode to get to Australia.

The first supermarket to scan the US invention was Sims in Melbourne’s western suburbs. The chain still exists to this day trading under the IGA name.

 

By 1986, 90 per cent of grocery items in Australian supermarket would have a unique barcode.

Today, at least 10 billion barcodes are scanned each and every day across the globe.

 

However, could it all be about to come to an end?

 

Amazon’s newfangled Go stores are supermarkets without check-outs.

 

Customers simply pick up the products they want, put them in a bag and walk out. The total amount is automatically deducted from their Amazon account. As such, bar codes may now longer be needed on products.

 

But, before the barcode’s obituary is written just yet, consider this. When you go to Amazon Go you still have to download a code to your phone and scan when entering the store. Maybe there’s life in the old barcode yet.
