Read this if you are a division of motor vehicles, or interested in mDLs.
You drive to the airport, and are pulled over by law enforcement. They check your driver’s license. You arrive at the airport, and rush through the TSA checkpoint. They check your driver’s license. You buy a drink in the airport bar to calm your nerves. They check your driver’s license. You board your plane, take off, land in your destination, and rent a car. They check your driver’s license. You drive to the hotel and check yourself in. They check your driver’s license. From run-ins with law enforcement, to traveling, to purchasing alcohol, driver’s licenses are necessary and versatile parts of every citizen’s identification arsenal—and soon, they will be mobile. But this new frontier of electronic identification—despite widespread applicability and increased holder convenience—brings challenges for mDL issuers and mDL-reading establishments.
The mDLs must function in a range of scenarios, each of which with distinct business processes, differing levels of holder data control, and various levels of online functionality. The widespread applicability of mDLs mean that state, county, and local issuing authorities need to simultaneously anticipate the range of mDL holder scenarios, identify the functionality required to meet these scenarios, and anticipate implementation challenges.
Additionally, understanding mDL functionality requires understanding the specific terms used to describe that functionality, and these terms vary. From the participants in mDL transactions, to the kinds of transactions occurring, to the various screens and data validation methods, this terminology quickly becomes complicated.
Table 1, Key Terms and Definitions below contains a list of mDL-related terms and definitions used within this blog, and accompanying future functional needs blogs.
| Table 1: Key Terms and Definitions |
| Terms |
Definitions |
| mDL issuer |
The department of motor vehicles or bureau of motor vehicles responsible for administering rights to, and overseeing distribution of, mDL data to mDL holders. |
| mDL holder |
The person whose data is contained in, and represented by, the mDL. |
| mDL reader |
The hardware technology used to consume mDL data from an mDL holder's device. |
| mDL-reading establishment |
The institution consuming mDL data via an mDL reader, e.g., law enforcement, liquor store, Transportation Safety Administration. |
| Portrait image |
The image of the mDL holder used to verify the holder's ownership of the mDL by visual means. |
| Attended operation |
The mDL-reading establishment is physically present when the mDL holder is certified as the owner of the mDL data. E.g., checking in at a hotel, buying alcohol at a liquor store, verifying ID during a traffic stop scenario. |
| Unattended operation |
The mDL-reading establishment is not physically present when the mDL holder is certified as the owner of the mDL data. E.g., verifying age during an internet transaction. |
| Personal Identification Number (PIN) |
A number (usually 4 digits) created by an mDL holder and used to validate their identity during transactions. |
| Use Case |
A situation in which a holder will rely upon an mDL to convey their data to mDL-reading establishments, for a defined purpose. |
Table 2, mDL Use Cases below lists situations in which mDL transactions are common, called use cases, and marks them as primary or future mDL use cases. Table 2 also categorizes whether the transactions occur with online/offline functionality (or both); and whether the transactions require both parties to be present during the transaction (attended), do not require both parties to be present during the transaction (unattended), or both.
Note that mDL use cases are ever evolving, as is the functionality required to complete them. For the most up-to-date content, consider reviewing resources developed by the American Association of Motor Vehicle Administrators (AAMVA) or the International Organization for Standardization (ISO).
