I guess I am really leery of cellphone security and app resilience. Is it so complex that it's too finicky to use? Does it require a good internet connection to work? ( Can you hear me now? ), or maybe it's based on QR codes?

I have been wrestling with a fast-food burger app over login issues. I am quite jaded over trusting anything I have to log on to to get a fresh timeout permission. For this, all I am risking is the cost of a trip to the restaurant vs. the liklihood the coupon offer will still work when I present at the register. ( The Wendy's Story already discussed here ).

How much impact would a denial-of-service cause for you? How robust is this technology. I've already seen the most expensive cars shut down for the most trivial crap. That's why I drive an old one made before their design became enshittified.
