You can now use your cell phone to pay for your SEPTA ride — and for the rides of any friends you have with you.

Called “SEPTA Key Tix,” the mobile payment option is now available to anyone who downloads the beta version of the transit authority’s Apple or Android app. The QR code fares currently work on all transit modes except for Regional Rail, which SEPTA says is coming sometime next year.

To buy the passes, you also need to have a credit or debit card, plus an online SEPTA Key account (which is free to create on the app).

Like a regular SEPTA Key tap, the $2 mobile passes include one free transfer within two hours.

Unlike a Key card, however, the QR code lets you swipe through multiple people at once. Just enter the number of people going for a ride — up to five at once — and buy the pass.
