Will an airline gate agent scan an iPad?

In my case, it's because my long-haired pets, who stay in the house when I go to work, don't do so well when it gets above 85F. I can program the thermostat to let the temperature creep up to that level when I'm out, but, seeing as I live in Las Vegas, even when set at 85, the air conditioner is going to be on for most of the summer.

Doubtful.
