People looking for iPhone 4S cases that will also help keep track of the other things in their pocket should take a look at the iLID-mk1 iPhone wallet, which the company said is the thinnest iPhone wallet on the market.

"Easily attaching to the back of your iPhone 4 and 4s, and impossibly thin at a sleek 17 mms thin," according to iLID. "The iLid-mk1 iPhone wallet has been thoughtfully styled to remain invisible so as to not give away its true nature. With inbuilt reinforced hinges, refined clasp and fluted lid, this design is the new benchmark for iphone wallets."

The device is made from a tough polycarbonate shell that has a soft touch finish. The company wanted to create a device that gave everything they needed with nothing additional that was not necessary. Adam Norich, CEO of iLID, said that they have been working on the product for about a year and are looking to sell it worldwide by the end of 2012.

ILID's website said the phone cases will also look to keep the iPhone safe in addition to the clips that will help lock all of the cards and other wallet items in the phone.
