Update: Some offers mentioned below are no longer available. View the current offers here.
Through February 28, 2015, you can earn up to 4,000 United miles when you connect a Chase United MileagePlus card to the Softcard contactless payment app for Android and Windows phones, and make purchases via the app with the linked card.
You'll earn 2,500 United MileagePlus miles for connecting a United card and making your first Softcard purchase; then earn an additional 500 miles for each month (through February 28, 2015) in which you make a Softcard purchase.
Softcard (formerly named Isis Wallet) is a joint venture between AT&T, Verizon and T-Mobile that enables you to make payments by tapping your smartphone against special contactless payment kiosks at participating businesses such as Petco, Chevron, Rite Aid, Walgreens, McDonald's and Subway, as well as independent stores and restaurants. In addition to Chase cards (like the co-branded United cards, as well as Freedom (No longer open to new applicants) and Sapphire Preferred), you can link eligible Wells Fargo and American Express cards (such as Everyday, Amex Platinum, and Premier Rewards Gold.
To enroll in this United bonus offer, download the Softcard app to a compatible Android or Windows smartphone by February 28, 2015, add any Chase United MileagePlus card to Softcard, and be sure to click on Activate Card. Once you've added and activated your card, click to see the back of your card and follow the steps to register your 8-digit MileagePlus number with Softcard. You can then start making purchases via the app to earn your bonus miles.
Meanwhile, you'll also earn rewards already associated with the Chase United cards, such as the United MileagePlus Explorer Card (2x per $1 spent on United tickets, and 1x per $1 on all other purchases), United MileagePlus Explorer Business (2x per $1 spent on United tickets and at gas stations, restaurants and office supply stores), and United MileagePlus Club (2x per $1 on United tickets and 1.5x per $1 on all other purchases).
If you have a United card and compatible phone, and shop somewere that accepts Softcard, then this promotion is a no-brainer. I value United miles at 1.5 cents apiece, so the Softcard bonus is worth up to $60 in free travel (depending on whether you're able to earn the extra 500 miles each month).
