In addition to the German ID card and passport, there are countless other ID documents. The basic distinguishing feature is the so-called eID function. eID is the abbreviation for electronic or digital identity. In order to facilitate online identification, a microchip has been integrated into the German identity card since 2010. This can be read by smartphones via the NFC interface. ID documents without an eID cannot be read electronically. However, the data can be read with the appropriate technology via text recognition, so-called OCR (optical character recognition).
