If you’ve had trouble getting seats to Taylor Swift’s Eras Tour appearances at Gillette Stadium in Foxboro on May 19-21 – and you have – here’s another chance to pick up a ticket: Capital One is hosting a giveaway at its Harvard Square and Assembly Row café locations Tuesday through Friday. (At two locations in Boston, too.)

The bank has pairs of tickets to each of the three Boston shows to give away, according to a Wednesday email from the bank.

Anyone can participate, according to the bank – they just need to stop into any café location and use their phone to scan a QR code on a sign inside or staff lanyard. There’s only one entry per person.

Two winners will be selected at random for each show and notified by email, which means winners will be going solo. The tickets will be transferred digitally, the bank said.

The Harvard Square café is at 24 JFK St., Cambridge, and is open 7 a.m. to 7 p.m. The Assembly Row café is at 425 Revolution Drive, Somerville, and is open 6:30 a.m. to 7 p.m.
