Accessing electronic communications networks requires the regular emission of certain data packets in order to discover or maintain a connection with the network or other devices on the network. Furthermore, devices must have a unique address assigned in order to be identifiable on that network. Wireless and cellular telephone standards similarly involve the emission of active signals containing unique identifiers such as a MAC address, the IMEI (International Mobile Station Equipment Identity), the IMSI etc. A single wireless base station (i.e. a transmitter and receiver), such as a wireless access point, has a specific range within which such information may be captured. Service providers have emerged who offer tracking services based on the scanning of equipment related information with diverse functionalities, including people counting, providing data on the number of people waiting in line, ascertaining the number of people in a specific area, etc. This information may be used for more intrusive purposes, such as to send commercial messages to end-users, for example when they enter stores, with personalized offers. While some of these functionalities do not entail high privacy risks, others do, for example, those involving the tracking of individuals over time, including repeated visits to specified locations. Providers engaged in such practices should display prominent notices located on the edge of the area of coverage informing end-users prior to entering the defined area that the technology is in operation within a given perimeter, the purpose of the tracking, the person responsible for it and the existence of any measure the end-user of the terminal equipment can take to minimize or stop the collection. Additional information should be provided where personal data are collected pursuant to Article 13 of Regulation (EU) 2016/679.
