RFID (Radio Frequency Identification System) enables the automatic identification and localisation of objects for the recording, storage and evaluation of data via radio. The system consists of a transponder (also known as a radio tag), which is located on or in the object or living being and contains an identifying code, as well as a reader to read this code. RFID transponders in miniature format can also be implanted in pets or humans. The picture on the left shows a handheld reader, the picture on the right shows various transponders.

Such systems are now also being used by wineries and producers as protection against wine adulteration and tampering. The RFID number is clearly legible on the back label of the bottle. This makes it possible to prevent the distribution of wines and thus any black market activities. It also guarantees the authenticity of the wines. Each label is assigned a separate identification number, which is linked to the electronic parts of the labelling machine and the storage gates. In this way, information can be stored and traced between the chip and the customer or delivery database.
