Verify age by scanning an mDL
How can you verify age by scanning a digital ID or mobile drivers license (mDL)?
Each mDL application works slightly different, however most use standardized security protocols under ISO-18013-5. This standard limits what type of data may be transmitted and how. Generally, mDLs use one of two mechanisms to send information to the ID scanner (also known as the verifying party):
- Scanning of a barcode (similar to a physical ID)
- A secure Blutooth connection established by near field communication (NFC)
Can you save or store data from a scanned mDL?
Currently, mDLs which are scanned using Blutooth/NFC are governed under ISO-18013-5 which in many cases does not allow for retention of any information from a scanned digital ID. Data is displayed on the screen for the purpose of age verification, and then immediately flushed. Some digital IDs do allow certain types of businesses to retain data if a credential is approved in advance.
Can digital IDs be faked?
Digital IDs and mobile drivers licenses are much more difficult to fake than physical documents. They are validated with the state DMV at the time of issuance, and require a biometric identifier to open the document.
As a result of the security of digital IDs, many analysts expect an uptick in usage of fraudulent physical IDs.
