Italian cheese makers have used microchips to crack down on fakes.

CTOnews.com, August 20 (Xinhua)-- Italian Parmesan cheese makers have implanted microchips into the 90-pound cheese wheel (cheese wheel) in an effort to crack down on fakes.

According to the Wall Street Journal, the microchips can scan for a unique serial number, allowing buyers to confirm that they are buying real Parmesan, according to the Wall Street Journal. Parmesan cheese, which is officially protected by the European Union, must be produced in specific areas of the Amelia Romagne region of northern Italy and made in accordance with specific standards and techniques, and the name can only be used for cheese that is at least one year old. Parmesan cheese can sell at a high price because of its world-famous quality, while the common "Parmesan cheese" in the United States is usually an imitation.

The microchips are made of silicon, the size of a grain of sand, and are placed on a food safety label on a cheese wheel. According to CTOnews.com, buyers can scan the microchip for a unique serial number and use it to make sure what they buy is authentic. These chips use block chain technology and can be traced back to the source of milk used in cheese.

It is reported that these chips cannot be read remotely, and even if people accidentally eat it, they will not be able to track anyone.

In addition to cheese makers, other industries are also considering or planning to use these chips, such as pharmaceutical and auto parts manufacturers.
