If you want to electronically sign documents in Acrobat Reader DC, you must have a digital signature.
Follow these steps to set your digital signature:
Important the Eid card must be inserted before opening Acrobat Reader DC, otherwise the procedure will not work.
Note: Do your certificates appear, but you do not see 'Belgium eID PKCS#11 interface v2' under the 'PKCS#11 Modules and tokens' option? Then these are certificates that are found via the 'Keychain access' utility. You cannot provide a signature in this way.
You can now use your Signature certificate to sign in Acrobat Reader DC. The certificate will be offered by Acrobat Reader DC for the insertion of a digital signature.
This step is mandatory each time the eID card is changed
