mDL (ISO 18013-5)
An mDL, or mobile driving licence, is a driving licence stored and presented from a smartphone, built to the ISO/IEC 18013-5 standard so any conforming reader can accept it regardless of who issued it.
ISO 18013-5 defines two ways to present an mDL: offline over Bluetooth, NFC or a QR code straight to a nearby reader such as a car rental kiosk, and online over the internet to a remote relying party, both using end-to-end session encryption so the holder controls exactly which fields are shared. The EUDI Wallet uses the same standard for its driving licence credential, so an mDL issued as part of a EUDI Wallet works with any reader already deployed for ISO 18013-5.
