Accessories specialists Griffin present an iPhone 5 case designed specially for business on-the-go. Making a nod to the increasing popularity of Square mobile payments, Griffin presents a silicone phone case. The sleeve is made to cater to Square card reader users, featuring an insert at the bottom edge that holds the reader in place. The backside of the phone sleeve doubles as a storage area that can hold the reader when not in use. The utilitarian phone case is priced at a reasonable $20 USD and is now available via Griffin‘s website.
