Apple Pay should be interesting in MacOS Sierra, i wonder how many websites will be using this in the UK, Amazon UK would be great considering it's a site i use more often. Also am i right in thinking that it will be more secure because we wont have to enter in credit or debit card details?
Also does anyone know if Apple Pay is being accepted at HMV stores?
It will be much more secure yes, since the retailer you're buying from won't have any card details stored and you're never actually giving them your card number.
As for Amazon, it's the one retailer I use really, but I doubt they'll ever implement it since they've got their own thing going on with Amazon checkout or whatever it is.
Last time I was at HMV they still had ancient old chip and PIN machines, no contactless readers in sight!
