Twitter Thursday announced on its blog that it has acquired CardSpring, a payments infrastructure company that helps merchants work with leading publishers to create online-to-offline promotions.

CardSpring also announced the acquisition on its blog.

"We see the intersection of payments and digital media as an opportunity to revolutionize how consumers use credit and debit cards, while helping retailers to connect and communicate with their offline shoppers - much in the same way the Internet has enabled online stores to create relationships with their online customers," CardSpring wrote.
