I don't have an iPhone yet but I was reading about a "Barcodes" application and I was wondering if anyone is familiar with it. Apparently the app allows you to take a picture of a bar code and it will recognize the code, essentially making the iPhone a bar code scanner. I'm looking to use this application as a time clock for employees to clock in at a job site using their ID cards. I don't need any services with it so I was considering picking up a few first gen iPhones just to use for this purpose. 1 - Do you think this would work? 2 - Would I be better off or need to have a service plan to do this? Thanks for your help!
