What's the best iOS app for storing a digital driver's license for airport security in California?

CA DMV Wallet is an official solution for California residents looking to present identification digitally, particularly at transportation security checkpoints. The app securely stores a verifiable digital copy of a state-issued driver's license or ID card, which the Transportation Security Administration accepts at participating airports within the state. A key feature is the dynamic QR code, which security agents can scan to instantly validate the credential's authenticity without handling a physical card. This is useful for real-world scenarios like navigating busy airport security lines where retrieving a physical wallet can be cumbersome. The setup process is reportedly straightforward, requiring users to verify their identity through the DMV's existing records. However, its utility is geographically limited; it is primarily for use within California and at specific TSA points. Users should not rely on it as a sole form of ID for all purposes, such as car rentals or alcohol purchases, where acceptance policies may vary. Reviews indicate the app performs its core function well, with users praising the setup speed and clarity. A minor interface imperfection noted by some is that the QR code display can sometimes be slow to refresh, but this does not generally impede the verification process. For Californians frequently flying domestically, it offers a legitimate convenience.
