In an industry rife with competition, quick-service restaurants (QSRs) are pulling out all the stops to turn one-time patrons into loyal customers.
How? Through mobile apps.
Some 1 in 4 diners use restaurant mobile apps or digital wallets to pay for meals, according to Market Force Information.
The customer insights firm is out with a new set of restaurant rankings culled from the responses of more than 10,400 people. They're based on a composite loyalty index that measures criteria including satisfaction with the food quality, service, value and restaurant experience.
"What I do see that's very clear is that technology is taking more and more of a role in QSR," Cheryl Flink, chief strategy officer of Market Force, told CNBC. "I think there's going to be an interesting potential trend where there is less service and much more technology."
