PayByCar announced that it is once again collaborating with Massachusetts DOT to make more drivers aware of the Boston-based company’s low-touch, E-ZPass-enabled fuel payment solution. As part of a promotional campaign in effect through Labor Day (September 5), PaybyCar and 27 Alltown convenience stores are offering a limited-time, limited-quantity, 30-cents-per-gallon gas discount to new and existing PaybyCar enrollees. “MassDOT,” said highway administrator Jonathan Gulliver, “is always looking for ways to make travel safer and more secure, so we’re pleased [PayByCar] leverages E-ZPass technology to make refueling faster and easier. The ‘Driven by E-ZPass’ pay-by-text payment method is an innovation that continues to show promise and we look forward to the results of the program’s first-in-the-nation deployment here in Massachusetts.”
