Samsung Pay

I used Samsung pay for the first time yesterday and it worked flawlessly just like the demos I've watched online but the merchant did not have a NFC terminal so they didn't understand how I was able to pay. At first they said "we don't have apple pay" so I explained the service I was using but then they asked me for my ID and credit card which brings me to the problem, they said your receipt card number does not match your physical card number. After some more explaining and handing my phone over to show the virtual card number which matched, I was finally able to complete my purchase. This is probably a one off situation but it almost makes me not want to use the service because of the huge hassle. Anyone else experience this?
