Digital keys that operate over NFC and/or UWB are compatible with a variety of mobile wallets. These digital keys can be stored in smart devices through the use of mobile wallets that have access to the device's embedded secure element, such as Google Wallet and Samsung Wallet for Android, Huawei Wallet for HarmonyOS, or Apple Wallet for iOS and watchOS.
In China, both Huawei Wallet and Samsung Wallet allow for emulation of unencrypted physical NFC tags. However, these emulated passes must be viewed in their respective Wallet apps before the device is tapped to transmit properly, unlike digital keys that are properly developed for such platforms.
The following is a list of digital keys and for what mobile wallets they are available.
Vehicles
The digital key specification for vehicles is maintained by the Car Connectivity Consortium. As of 2023, most implementations of the technology follow the Digital Key 2.0 standard. The first automobile to follow the Digital Key 3.0 standard was the BMW iX. Manufacturers can set limits on how many people a key can be shared with. For instance, Kia only allows 3, while Mercedes-Benz permits up to 16.
Some vehicles may need software or hardware upgrades to support a specific digital wallet. Also, not all trims for these listed models have the necessary hardware to support digital keys.
Keys that are compatible with Google Wallet, Samsung Wallet, and Apple Wallet can be shared across platforms.
