Use your PIN when you buy something with your Gimi Card in a shop. You can easily find the secret number in the Gimi app. Your PIN is a four digit code that might not be easy to remember.
Open your app and go to your Gimi Card. Tap on "View PIN" and type in your passcode. Your PIN will show up on your screen! Remember not to write it down or share it with anyone, not even your best friend.
