Two days ago I was in Tampere and tried to pay with my credit card (it is Raiffeisen Bank MasterCard which supports PayPass technology). I have never paid using it before but I was pretty sure that it doesn't require entering pin code since it is PayPass (I have used another MasterCard PayPass a lot in Russia and it never asked me to enter a pin). But both in McDonald's and in souvenir shop reading devices proposed me to enter pin. I found that really strange. Could you please share an idea what was wrong? Was the problem in those devices, in my card or in my understanding of what does PayPass guarantee me? It would be especially great if you live in Tampere or have visited it recently and tried to use PayPass card there.
P.S. Please, note, that in both cases total amounts of money I should have paid were relatively small (less than 10 euro).
