eIDde

eIDde refers to the electronic identification (eID) system of Germany, officially known as the Personalausweis mit Online-Ausweisfunktion (ID card with online ID function). This feature, integrated into the German identity card since November 1, 2010, allows citizens to authenticate themselves electronically with authorities, businesses, and other service providers.

The eIDde function enables secure online identification and authentication. Users can present their eID card to a reader and, after entering their personal identification number (PIN), confirm their identity online. This process uses cryptographic methods to ensure the authenticity and integrity of the transmitted data, protecting against unauthorized access and identity theft. The system is designed to be privacy-preserving, with users typically controlling which data is shared for each specific transaction.

To use the eIDde function, individuals need an activated online ID function on their identity card, a compatible card reader or a smartphone with Near Field Communication (NFC) capability, and the correct PIN. This technology facilitates access to a growing range of online services, including government portals, online banking, and e-commerce platforms, offering a convenient and secure alternative to traditional login methods. The development and implementation of eIDde are part of a broader European initiative to establish cross-border digital identification.
