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 for Android & Wear OS, Samsung Wallet for Android, Huawei Wallet for HarmonyOS, or Apple Wallet for iOS & watchOS. In some regions, 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 cars is maintained by the Car Connectivity Consortium. The first automobile to follow the Digital Key 3.0 standard was the BMW iX. Manufacturers can set limits on how many devices a key can be shared with. For instance, Kia only allows 15, while Mercedes-Benz permits up to 32. 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.
* = While key can function in NFC mode, the manufacturer disallows devices without UWB from being able to add the key. Keys that are compatible with Google Wallet, Samsung Wallet, and Apple Wallet can be shared across platforms. Google Wallet, Samsung Wallet, and Apple Wallet are capable of the following remote commands for supported vehicles: unlocking, locking, climate controls, sounding the horn, and opening/closing the trunk.
Locks and external readers
In 2023, a new communication protocol named Aliro was announced by the Connectivity Standards Alliance to promote interoperability between smartphones, smartwatches, and access control readers, and guarantees improved availability for digital keys for locks across the major mobile wallets. Google, Samsung, and Apple have all been announced as participating members. The standard launched on February 26, 2026.
Hospitality and entertainment Businesses can set limits on how many devices a key can be shared with. For instance, Hyatt only allows one smartphone and one smartwatch, Lore Group allows two each, and Hotel June allows up to four.
