New Mexico has allowed residents to store their driver’s licenses and state IDs in Google Wallet, becoming the sixth state to do so after California, Arizona, Colorado, Georgia, and Maryland. Physical identification is still necessary for law enforcement and age verification, but many businesses and TSA checkpoints are using the NM Verifier app for smartphone-based verification. Google Wallet will soon introduce digital passport IDs, enabling users to store a digital version of their U.S. passport. Users can create a digital U.S. passport ID by selecting the option in Google Wallet and following on-screen instructions. Travelers are advised to continue carrying physical IDs until digital IDs are more widely accepted and to check the TSA’s map for supported states and airports when planning domestic flights.
