A few categories: - Many hotels no longer accept cash (this was gradual; it was formerly an increasingly large deposit to stay with cash) - Many vending machines will not take cash; either by design or due to disrepair on the bill feeder. - Specific areas where you can find out ahead of time that cash will not be accepted: (music festivals, airplane flights &c.) I have only seen a few traditional stores with no-cash, but I expect it to accelerate.
