1. Tap-to-pay does not work at Costco stores or gas pumps. Instead, insert your card into the merchant terminal to pay.

2. You can purchase a Costco Shop card online with a Mastercard credit card and then use it for in-store purchases and fuel.

Mastercard debit and credit card acceptance information is based on information provided by Costco through its website and store personnel. Acceptance practices may vary by location and transaction type, and may change over time. Individual experiences may differ.
