On one hand, I really like this because it does make it more convenient to use vending machines by removing the need for cash and coins. The other side of that coin, however, is I feel it'll make me less selective and I'll end up paying their marked up prices since the cost will seem "less real." Parting with real cash makes me less inclined to spend $1.25 on a soda, but if all I have to do is tap and "pay later" I'll probably give in to temptation more often.
