haptic feedback for card readers

It seems like everything has now embraced 'contactless' technology, although in nearly all these contactless interactions, your bank card/ travel card/ iPhone/ Apple Watch/ magic wand/ etc. or the hand that is holding one of these does make some contact with the reader. Therefore the reader should provide a tiny jolt of haptic feedback during the interaction to show that the transaction has worked - the reader is mains-powered so (unlike haptic feedback on your phone) there isn't a power-conservation issue.

I know that these readers provide other kinds of feedback too (e.g. a beep) but people don't hear this if they're wearing headphones, and if the combination of feedback makes a transaction complete slightly faster this could be immensely beneficial. On a transport system like the London Underground, with 5m passenger-journeys per day, the ticket barriers are a source of congestion, and shaving just a fraction of a second off the transaction could make a big difference.

       //magic wand/ etc// My two dogs are both chipped - I'm wondering if the technology exists to pay by spaniel.

       Yes it does, but you risk getting your change in chihuahuas ...

       While it might seem, on first glance, an excellent idea to enable canine-based contactless payment (so that you can, for example, stride purposefully into a coffee shop, make your order ("Coffee, please" - people who stride purposefully don't fanny about with lattes, cappuccinos and flat whites), and then command your faithful pet to go and pay for it ("Rover, pay! - good dog!")), after a very short period of time the colossal flaw of this approach will become evident, that is, that a reasonably intelligent dog will grasp the basic principle of contactless payment and will sneak off to the local butcher's with increasing frequency, returning to you looking a bit dazed and fatter.

       // looking a bit dazed //   

       Are there any Labradors that don't have a permanent "a bit dazed" look ?

       Sorry - "looking a bit more dazed than usual"

       It's just an act : they figger if they look a bit out of sorts, they'll get a sympathy doggie treat.   

       Meanwhile, idea [+] : my "tap'n'go" doesn't work all the time with every machine, and I can never remember which part of the card goes onto which part of the reader.

       //pay by spaniel//   

       My spaniel has gone grey around the muzzle and developed an uncanny resemblance to Clemenceau. Do you think that would impact his payment limit?

       Of course it will, but in a good way. He can extort massive reparations from the Germans under the Versailles treaty.

       Our cat is chipped - does this mean I can "wave the pussy" to get train rides?

       You're more likely to get arrested - or, depending on where you are, accosted ...
