Health insurance card for the NRW police
The NRW police are switching to the health insurance card. The paper sickness certificates will be replaced by a health insurance card for all police officers in NRW by 2018.
Ministry of the Interior of the State of North Rhine-Westphalia

The card stores the first name, surname, date of birth, gender, insurance number and the address of the NRW State Office for Central Police Services and billing data/information.
The health insurance card is valid without a photograph, as this is not the electronic health card (eGK) issued to people with statutory health insurance. As a so-called "other cost bearer", the NRW police cannot issue an eGK. Nevertheless, the issued health insurance card can be read by a reader in doctors' surgeries.
