This is a handy tool to have when you go out.  Keep it on your key chain for easy access.  Great for those times when you can't tap your card and after all you've done to not touch anything in the store, you end up having to enter your PIN number with your fingers.

It does have a rubber tip for use as a stylus with iPads and phones, as long as they are without screen protectors.  Can open some doors, obviously, not doors with round handles and cupboards.  

Great for elevators, accessibility door openers, bank machines, debit machines, even has a bottle opener!
