I've read in numerous locations about the arrival of POS functionality in the realm of iPhone or iPod touch. I own a small biz where employees use barcode scanners for input into data fields appearing on our mobile-optimized web pages. In other words they shoot a bar code and the data appears where the cursor is and a return command is sent. We don't want to have an app written in order to utilize the external data gathering devices like a bar code scanner. Can a barcode scanner be used or not? If so is there a manufacturer for a port mounted scanner (like what the Apple Store is supposed to be getting) or can the Bluetooth radio be utilized like other hand held devices? Thanks for any help!
