Atlanta-based Chick-fil-A has rolled out a new mobile payment system in Arizona that enables customers to use their smartphones to pay for meals via a special app.

A growing number of retailers have begun mobile payment options, including coffee-shop giant Starbucks, which introduced its payment app about five years ago.

Chick-fil-A unveiled the new app Tuesday at its 24 company-owned restaurants in Arizona, including two in Tucson.

Chick-fil-A customers can download the company’s free app from the iTunes App Store for iOS or Google Play for Android devices. Once the app is downloaded, customers can register for an account and load funds onto their account using credit card information. When customers are ready to pay, they tap the “Pay” button and scan their account’s unique Quick Response Code (QR code) at the register or drive-through lane. The cost of the meal is automatically deducted from the account balance.

Chick-fil-A has outfitted each of the participating restaurants with special scanners that also will allow for faster and easier transactions, Michael Lage, manager of Chick-fil-A’s mobile strategy, said in a news release.

The system is available at the two company-owned restaurants in Tucson, at 3605 E. Broadway and 4585 N. Oracle Road. The location at the University of Arizona Student Union is operated by a licensee and does not have the mobile payment system.

The system is rolling out nationally after its initial successful test in the Greensboro/Winston-Salem and Raleigh-Durham, N.C. markets earlier this year. The option is now available in seven states.
