KEEDOOZLE

A. Most experts say that no technological innovations appeared in shopping until the year 1974

when bar codes were introduced. But few people realize that as early as 1916 Clarence

Saunders founded the first self-service supermarket and then, 21 years later, he decided to

take self-service to an entirely different level and introduced Keedoozle, a truly futuristic

idea at the time. Keedoozle – short for “key does all” – was the world’s first automated

supermarket.

B. Saunders’ Keedoozle used a vending machine concept, offering sample grocery products at

reduced prices behind small glass boxes. On entering the supermarket, shoppers collected

a key with a special tape attached to it; they would insert the key into the keyhole in front of

the product they wanted, and an electric signal would punch the tape accordingly. At the end

of their trip they would give the key to the cashier, who would insert it into a machine that

would read it and electronically signal the staff in the stockroom to collect the products.

They were instantly sent down a conveyor belt to the front end where they would be packed

and ready to go.

C. Saunders tried the Keedoozle concept three times, but failed every time because the circuits

couldn’t handle the traffic during peak hours. Customers regularly got mixed-up orders.

In addition, the conveyor-belt system wasn’t fast or efficient enough when there was high

demand. In consequence, Keedoozle closed its doors for good in 1949. However, Saunders’

idea has successfully been implemented in the South Korean underground. People can find

photos of products pasted onto the walls. Each of the photos has a special QR-code

embedded in it. So, while waiting for the train, customers can use their smartphones to scan

the codes of desired products, which are then delivered to their homes.
