George Laurer, co-inventor of the barcode, dies at 94

George Laurer, the US engineer who helped develop the barcode, has died at the age of 94.

Barcodes, which are made up of black stripes of varying thickness and a 12-digit number, help identify products and transformed the world of retail.

They are now found on products all over the world.

The idea was pioneered by a fellow IBM employee, but it was not until Laurer developed a scanner that could read codes digitally that it took off.

Laurer died last Thursday at his home in Wendell, North Carolina, and his funeral was held on Monday.
