1) you have a small dog, who you put in a cage
2) you go out of town for a several hours
3) you can not get back in time for a couple of days
4) you have no one who can enter your home and unlock poor dog
hundreds of millions of dog owners would be thankful, IF THERE WAS A PHONE APPLICATION to do this simple task
unfortunately this very old (1992) invention is patented and not being used.
