Set up your Wallet app
You can download Google Wallet on Google Play and the Apple App Store if you're in the US. Wallet works on mobile devices running Android 4.0.3 (Ice Cream Sandwich) or higher, and iOS 7 or higher.
If you're using Wallet for the first time:
Open the Wallet app. Sign in with your Google Account.
Enter your 5-digit US zip code. Touch the checkmark.
Choose your email preference. Select the option you want.
Review the terms of service. If you agree to these terms, touch Agree and continue at the bottom of the screen.
Create a Payments PIN. Enter a new four-digit PIN. You will use this PIN to verify access to the Wallet app, and to make debit transactions and cash withdrawals using the Google Wallet Card.
Confirm PIN. Re-enter your four-digit Payments PIN.
