I am looking for an IPhone app that will scan two bar-codes, one bar-code on a delivery docket and one bar-code on a delivery point, and if the two match it will turn on a 12v 10A switch. I'm thinking that the Iphone would bluetooth to an Arduino Uno which turns on the switch. I would like to have the Iphone docked to charger before the switch is engaged to keep me from losing the IPhone. If the dash switch is engaged and the bar-codes match the electromagnet servo will engage. If the bar-codes don't match or the dash switch does not turn on with-in 10 min of the bar-codes being scanned nothing happens. The Arduino switch turns off when dash switch has been turned off. The IPhone (bar-codes) are 50 meters from the Arduino Uno when it's scanning, but 1 meter away when docked. There would be 15 different product bar-codes types. The bar-codes would be identical except for one would be a delivery point and one would be the delivery docket.
