Rule n° 203 - Information relative to transaction security is indicated.

On the Internet, transactions usually involve the transfer of sensitive data including credit card numbers. To prevent interception of data, it is important to encrypt them. It is also useful to inform the user about security measures.

  • Inform users about the security of exchanges of sensitive data.


Indicate the mode (SSL, TLS) and the level of data encryption (128 or 256 bits, etc.) on the relevant pages. An indication of how to find the information using the browser can be given since most browsers are able to do this.


In a website offering online transactions: check that information on the level and mode of data encryption can easily be found, for example from a help page or an FAQ. If the procedure indicates how to find information in a browser interface, it must refer to the main browsers on the market.
