Costco Changes Checkout Forever: What the New in-App Payment System Means for Your Next Trip
By Sarah Jenkins
Can I link non-Visa payment methods to the in-app checkout barcode?
No. While Costco.com accepts Mastercard and Discover, physical warehouse locations in the United States exclusively process Visa credit cards and PIN debit cards. The in-app payment system will reject non-Visa credit cards added for warehouse checkout use.
Does the app work if my phone loses cell reception inside the warehouse?
Yes, provided you open the app while connected to the complimentary warehouse Wi-Fi network. The app caches a limited sequence of dynamic security tokens that allow code generation offline for several minutes, though you must authenticate your login credentials before reaching dead zones.
Will the app payment barcode work at Costco gas station pumps?
The digital membership barcode scans at optical gas pump readers to authorize the pump, but payment execution depends on local pump hardware. Most modern pumps process the transaction directly from the mobile app, though older pump dispensers in un-renovated locations may still require an NFC tap or physical card insertion.
What happens if my in-store purchase exceeds the mobile wallet's daily dollar cap?
If your basket total surpasses the internal daily digital limit (typically capped between $1,500 and $2,500 depending on account history), the POS register will prompt the cashier to process payment via traditional physical card insertion or contactless terminal tap.
