It is possible, it is in the Cisco website somewhere under your login, i lost all my web links so i can't remember where it is now. Basically you can send your employer the official info from Cisco and you can also give him/her a login to check it also.
John is correct. You can publish credentials in the Certification Tracking System (www.cisco.com/go/certifications/login) to allow you employer or other 3rd parties to verify your valid certifications. Please click here for specific instrcutions.
