Wow, you seriously believe that? Do you think merchants and card companies are taking the loss and not increasing fees per transactions and final price of the product?
It's like insurance, cheap if you don't drive , once you go out in the city 3 accidents in 6 years and you're in the next class, the price goes from 210 euros to 450.
I've been using credit cards every day, everywhere, for 20+ years. I've seen a fraudulent charge a grand total of one time. My bank instantly reversed the charges, reissued the card and I never heard about it ever again. The whole issue is being blown out of proportion.
Debit cards are not different at all from credit cards here if we speak on how they work.
Both have pins, both have customer protection, with both you can seek a refund in 45 days, the only difference is that you can spend more than you have when it comes to credit.
For example, I own 1 Mastercard credit (for times I find a good deal and low on funds) and 1 Visa debit contactless at ING (day to day purchases) and another Citi Visa debit (for internet purchases), I was forced to ask for refunds on all of them, all were solved in less than 7 days and I haven't yet run into a situation where there was an unknown charge in any of my accounts.
So your far better and safer without the PIN....sorry but I can't find any logic in this.
