PowerPay is like an E-Z Pass for sports fans, a cashless technology for buying beer and food in a hurry. Starting with tonight’s soccer match at Lincoln Financial Field, fans can get a free, thin plastic tag that has an Eagles logo printed on the outside and a tiny antenna and radio-frequency identification chip embedded inside. It can be used like cash at the more than 300 permanent concession stands at the Linc.
Fans can link the tag to any existing credit card, but if a fan also signs up for the Eagles’ new Extra Points MasterCard, each dollar spent accumulates one point toward prizes, such as autographed jerseys or even dinner with a player. And 3,000 of those new MasterCards will be available with the chip technology built in, eliminating the need for the separate tag. They’ll go first-come, first-served at the stadium or at www.eaglesextrapoints.com
