The German ID card, the residence permit and the eID card for EU citizens contain an NFC chip card on which your data is stored. A smartphone with NFC functionality serves as a reader and transmits the data via an encrypted channel. In order for your ID card data to be read for identification, it is essential to activate NFC in the smartphone settings.
On most devices, the NFC interface is located on the back in the middle to upper area. On iPhones, the NFC interface is uniformly located on the upper edge on the back of the smartphone on all supported devices (iPhone 7 or later). The smartphone used for identification does not have to be your own, because no data is stored on the device during the identification process.
