Square and Griffin Technology are showing off a new iPhone case optimized for businesses using Square Reader at CES this week. It’s called the Merchant Case.

The case fits the iPhone 5s and iPhone 5, and was designed with Square customers in mind. As the companies explain:

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. 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.

“Griffin is proud to be Square’s inaugural partner in its Works with Square program,” said J. Curtis, Director of B2B Product Development at Griffin. “Our Merchant case is the first protective case designed to augment and provide storage for the Square Reader. Paired together, our Merchant case and Square Reader create the ideal point of sale solution for all businesses on the go.”

The case is part of a “Works with Square” accessories line featuring products designed for Square merchants. Expect to see more of these in the future.

Merchant Case works with Square Register and costs $19.99.

Last month, Square reduced the price of its Square Stand tablet accessory to $99. It was originally $299.
