HUNDRED DISCOVERY: even when they invented the field. She got her around

Pp, pp, pp. A monotonous sound at the cash register signals five times. First, this way of identifying goods changed the world’s trade and our everyday purchases. The series on the most significant human discoveries was published by Magazn Vkend.

Perhaps each of us overheard a conversation in some form. Sale: Aniko, how do you, please, pudding donut? Vendor from next door: 1845, Karlku. I hurt you twice today.

My traditional pieces of pastries, fruits and vegetables in the shopping coke are well-known at the cash register, because their specific brigdns do not remember. It means confused lettering, dissatisfied queuing, subsequent panic and chaos.

He was introduced to the idea by his colleague Bernard Silver, with whom a certain salesman had previously worked.

Today, every day around the world, there are five billion innovations that will make the typical push. It’s so easy that we can do it ourselves at self-service checkouts. And the same system is used all over the world for less than 110 degrees.

Czechoslovakia was the first in the former entrance block and was surrounded by darkness. The British national Tesco had a domestic delicacy on the shelves, but needed to provide it with packaging first EAN (European Article Number), so its republic became one of its users in 1983.

The introduction of a single label was very slow in our country, at first it was about all export pieces and it was rewarded and abroad. The first Czech song was made in 1985 in the Prague House of Elegance. To go in 1991, only 15 percent of domestic products were provided. Today, more than seven thousand companies use the system.
