Square’s Card Reader is now available in AT&T stores, as well as locations like Target, Walgreens, Best Buy, and a number of other retailers. The reader, which is free from Square’s website, costs $9.99 in stores. Square will reimburse purchasers for the cost of the device, which adds a bit of “wonkiness” to the “free” card but will ultimately get it in front of more mainstream shoppers.
