Service Description
ident ident is an online or remote identification service for German eID documents. Other identification documents cannot be used right now due to regulatory and technical restrictions. The end user needs their eID card, their PIN and a compatible app on their smartphone to be identified at a high level of assurance.
onsite onsite supports the face-to-face identification in a branch office or store. Many different identification documents can be processed. In case of eID cards, the data is extracted from the contained chip. The CAN is used to access the chip. In case of other ID documents (e.g. passports or ID cards), the data is collected via OCR (for a growing number of documents). For unsupported documents, a photo is taken and relevant identification data can be entered manually.

Qualified Electronic Signature (QES) A QES allows for completely digital signing processes. It replaces the need for physical documents to be signed by hand.
IDA IDA stands for Identifizierungsdiensteanbieter (identification service provider). AUTHADA is certified as IDA and is therefore allowed to acess the German eID in any business use case.
