跟我走英文Beep！Beep！Barcode（条形码）technology makes it faster and easier to buy things in stores.You've probably en the black-and-white pattern on product packaging.This year,this great invention is 50 years old！
On a Sunday afternoon in 1971，IBM engineer George Laurer came up with a code that
could be printed on food packages.It became the basis for the Universal Product Code,which was ud by many companies starting in1973，according to The New York Times.Before this,cashiers（收银员）had to type prices by hand .
Time has proven it to be a great invention.Today,barcodes are scanned over 6 billion times every day and ud by 2 million companies worldwide,PR Newswire reported.
A barcode is really a simple idea：give each product a unique number and print it for a scanning device to read.What information does a barcode contain？Where the product comes from,where it has been,its price,u name it.It can also help stores keep track of their products.For example,if there are 10 boxes of milk and a customer bus one,it will be recorded so that the store owner knows there are nine boxes left.In the 1980s,libraries started using barcodes to keep track of books in this way.
The next generation of barcodes,such as OR codes,can hold more information."They can tell consumers if a product contains allergens（过敏原）or if it is organic（有机的），This provides customers with more trust in the products they buy,"said GS 1，an organization that develops global barcode standards.The development of codes will surely make people's life better,and there is a lot to expect.
