Wallet

Hello. Open Samsung Wallet and go through the guided set-up process[es].

Please follow the below: 
Run Samsung Pay on your phone. When you open the app, you will be prompted to download and install the complete app. This is necessary because the full version of the app is not pre-installed.

You will be asked to sign into your Samsung account. If you have one already, simply enter your login data. If you do not have a Samsung account, you must create one through Samsung Wallet. If the account is already logged in, tap the “Start” button. Then, read and agree to the terms and conditions, and click the “Next” option.

Now you will have to set up a verification method for using Samsung Wallet. You can use the iris scanner (if your phone has one), the fingerprint reader, or the PIN option.

Create a 4-digit Samsung Wallet PIN.

Now you can add your first credit or debit card to Samsung Wallet and use it to make payments.
