Griffin Technology and Square have introduced the Merchant case for iPhone 5s and iPhone 5 at this week's Consumer Electronics Show in Las Vegas. They say it's first protective case optimized for a Square Reader.

Griffin’s new Merchant case builds on Square’s selling experience for mobile businesses. The introduction of the Merchant case launches Works with Square, a program that allows developers to build accessories for Square businesses.

The case is custom-molded to secure the Square Reader when connected. A groove in the bottom of the case aligns with the Square Reader to guide a credit card to an easy, consistent swipe time after time, according to J. Curtis, director of B2B Product Development at Griffin.

Made from durable silicone, the case protects the phone from bumps and drops. The case’s non-slip sides and corners make it easier to hold the phone and to hand over for customers' signatures. Additionally, the Square Reader can be detached and stored in the back of the case when not in use.

The Merchant Case + Square Reader is available to order for US$19.99 at store.griffintechnology.com/merchant-square-case-for-iphone-5. Current orders are expected to ship within two weeks.
