Data protection issues relating to the use of RFID technology

The number of applications in which chips are used is growing by the day. RFID (radio frequency identification) uses radio waves to read and store data without the need for any contact or line of sight. Although there are certain areas where the use of RFID chips does not raise any data protection concerns, there are others which pose considerable risks for the private sphere of the population at large. It is therefore important that whenever this technology is used, measures are taken to prevent the unlawful processing of personal data.
