[4] It replaces the old Samsung Pay app on Android-powered Galaxy devices and is currently available in Australia, Bahrain, Brazil, Canada, China, Denmark, Finland, France, Germany, Hong Kong, India, Italy, Kazakhstan, Korea, Kuwait, Malaysia, Norway, Oman, Qatar, Saudi Arabia, Singapore, South Africa, Spain, Sweden, Switzerland, Taiwan, Vietnam, UAE, U.K. and U.S.[5][6] Samsung Wallet also supports a variety of transit cards, such as T-money and cashbee in South Korea, as well as Octopus in Hong Kong.

However, due to the region-specific nature of Samsung Wallet, users from other regions are not able to utilize these transit cards from their own devices.

This can be mitigated in a sense by using a Galaxy Watch to split the Fast Mode passes between multiple devices.

Payment cards can also be used without prior authentication on select transit systems, though that mode is called "Tap & Pay.

[11] An interaction (or transaction) between a pass and a system is facilitated by a 1D or 2D code, although it requires the customer to initiate the activity.

[12] In August 2023, Samsung Wallet came to Wear OS for the first time with the launch of the Galaxy Watch6 with partial functionality of the Android app.

[27][8] 13 types of electronic certificates and IDs issued by the Government of South Korea via the Government24 service are supported by Samsung Wallet.

Once the credential is read, the ID holder must confirm the personal information they wish to share (full name, age, etc.)

Samsung has also announced plans for added credentials to be able to be requested by apps to present virtually in 2024.

[31] Starting from October 10, 2024, citizens of Kazakhstan can keep their national identity cards in Samsung Wallet.
