With the BKK Salzgitter APP, insured persons can communicate even easier, faster and easier with their company health insurance. Sign up for our loyalty programs, upload your bonus receipts and receive your bonus. Or submit your bills for special services, such as professional teeth cleaning or osteopathy, with us for reimbursement. Changes to personal data (address, bank details), photo upload for the health card or ordering a new card are easily possible. If a membership certificate is needed for a new employer, the UNI or other authorities, this is done with a click. The current status of your applications or inquiries can be found in the personal message mailbox of the app and all this via a secure access.
