From the announcement made on November 16th, 2022:
The Oklahoma Turnpike Authority is offering another option for fast, convenient and safe tolling with the addition of the PlusPass mobile app. PlusPass allows drivers to manage their account on their mobile device and pay tolls via credit card, PayPal, or cash. Drivers utilizing PlusPass will see savings of roughly 25 percent compared to PlatePay customers, as the app eliminates the costs of printing and mailing invoices.
PlusPass gives drivers who prefer to use cash the ability to take their phone to a participating retailer to load the app with up to $500. Participating retailers include CVS, Walgreens, and Family Dollar stores. PlusPass users can add money to their account as their travel needs require.
