Is Anybody Using Mobile Computer w/ Scanner and Ignition?

Has anyone successfully run an Ignition project on a mobile computer that has a barcode scanner? If so, we would like details on your hardware and configuration setup. We’ve tried using a Motorola MC9190 and a scan of an 11 character barcode takes >20 seconds to simply scan.
We can get things to respond reasonably quickly using the mobile module on an android or iphone, but these are not robust enough for the shop floor. Thanks.
