Last night i had a bit of a Titanic evening. I watched a few documentaries about the ship's sinking and about the background of the passengers. One mentioned a wealthy passenger who's body was found with 2,500 dollars in cash in his pockets.
Generally, I carry a similar amount to others and I use contactless where I can. I'll usually ask small shops if they have a preference for cash, if there's time, as I know some of them get stung for even contactless payments on small amounts.
ETA: The one time I carried a significant amount of cash was on a transatlantic journey to a country where cards are unreliable but apparently £20 notes were very welcome. It was stashed in pockets, a money belt, one boot (that was the get-us-back-to-the-airport emergency wedge

) and a couple of lockable compartments in different bags IIRC.
You can also do the same using your smartphone if you have the App.
What are the benefits and are they sufficient to outweigh the risk of the smartphone being much easier to hack remotely than a card?
Granted, living in a city makes this much more feasible than your post office and pub village but it really wasnt a hardship at all.
I'm pretty sure both post office and pub (in the next village - mine has neither any more) take cards. I think the main need for cash here is to buy fresh food from the smallholding stalls or to buy travel on the busopolies - Go-Ahead and the small independent competitors offer 5% off if you pay by card, while Stagecoach and First don't accept them at all!
In fact, over 2 weeks, the only time I regretted not having cash was to settle a food bill with a friend who didn't have any means of accepting online payment from me!
Anyone here tried mPay and how was it for you?
