Reinstate service numbers for military members, and remove the practice of including a social security number on govornment paperwork and ID cards. This will decrease identity theft, OPSEC and privacy act violations.
Add a three or four digit number on the back of a Beneficiaries Medicare card. The number would be required to bill Medicare. Use this number just like the CC companies do to confirm purchases.
Implementing this Idea would lower Medicare fraud and save millions.
