You will need to sync your PIN with your KOHO card when you make your first purchase. The purpose of this is to secure your account. The good news is that you only need to sync your PIN once, and then you can use the tap function going forward 🎉
Here's how you sync your PIN:
Make an in-store purchase after calling to activate your card
For this first transaction, insert your card + input your PIN
If your purchase happens to go through without you needing to input your PIN, don't worry, this happens from time to time. You're still all set up!
