Write an iPhone application

We have an existing application that was developed in house that is similar to the Square card reader appliction. We devloped it some time ago using an iMag Card Reader for the iphone 4. This card reader uses the iphone 4's 30 pin connector and as such does not work on any new devices. We have since selected the idtech ishuttle card reader which uses the headphone jack so it will work with new and old phones and also Android phones. We have done some development on the and android platform using this card reader but none on the newer iphones. We would like a developer to update our existing application to work with both the iMag card reader and the iShuttle card reader for iphone 4 through iphone5s and ipad2 through ipad air. We will give you documentation for interacting with our payment processing server and will send you the two card readers we want the application to support, along with any documentation that was given to us for use with the readers.
