For security-relevant applications - such as signature with Sign Live! CC or Internet banking, card readers are divided into security classes.

To generate a qualified electronic signature, you need card readers of the security class III. These devices are characterized, among other things, by the fact that they have a display in addition to the keyboard. Since Sign Live! CC the BSI has been certified, we recommend card readers that also have this certification.

A list of manufacturers and the names of the card readers tested can be found in   Sign Live! CC data sheet.
