Subway, Chop't are the latest to roll out mobile apps

Two more QSR chains are jumping on the mobile payment bandwagon. Subway and Chop't, the specialty salad chain, are both testing ways to allow consumers to pay for their meals using smartphones.

Subway has reportedly rolled out a test of its mobile payment app in 2,000 locations in California. So far, about 400,000 customers have downloaded the app, available for both iPhone and Android. 

Separately, Chop't sent an email to customers this week announcing a new mobile payment and loyalty app that will replace its Frequent Chop'r plastic card loyalty program. The app will allow customers to track purchases and rewards, and also access Chop't news and nutrition information on the go. Story
