Exchange Campaign Representative QDC

Due to the technology used, a certificate cannot be changed after issuance - the process necessarily involves Repeal of previous certificate and new certificate issuance.

The profile created by this means is the one of Representation (See Profile detail below), regardless of what profile through which the previous certificate was signed.

Please note that the cryptographic device that you have should be sent, along with the documentation (smart card or USB token). In case of having a smart card, the information printed on the card cannot be altered.

Representation Profile
Destined to identification of an organization, this qualified certificate profile is issued to a person who has powers of representation of that company or institution. This profile allows you to sign on behalf of your company or institution. In addition to the company's identifying information, it contains the ID of the representative and its powers of representation, beyond the possibility of specification of usage restrictions.
