Guidelines 03/2019 on processing of personal data through video devices
Section 7.2 Second layer information
117. The second layer information must also be made available at a place easily accessible to the data subject, for example as a complete information sheet available at a central location (e.g. information desk, reception or cashier) or displayed on an easy accessible poster. As mentioned above, the first layer warning sign has to refer clearly to the second layer information. In addition, it is best if the first layer information refers to a digital source (e.g. QR-code or a website address) of the second layer. However, the information should also be easily available non-digitally. It should be possible to access the second layer information without entering the surveyed area, especially if the information is provided digitally (this can be achieved for exampleby a link). Other appropriate means could be a phone number that can be called. However the information is provided, it must contain all that is mandatory under Article 13 GDPR.
118. In addition to these options, and also to make them more effective, the EDPB promotes the use of technological means to provide information to data subjects. This may include for instance; geo-locating cameras and including information in mapping apps or websites so that individuals can easily, on the one hand, identify and specify the video sources related to the exercise of their rights, and on the other hand, obtain more detailed information on the processing operation.
119. Example: A shop owner is monitoring his shop. To comply with Article 13 it is sufficient to place a warning sign at an easy visible point at the entrance of his shop, which contains the first layer information. In addition, he has to provide an information sheet containing the second layer information at the cashier or any other central and easy accessible location in his shop.
