Would I ever need credit card if my debit card is issued by MasterCard/Visa?
Need is a strong word. As far as merchants are concerned, if they accept, e.g., Visa credit, they will accept Visa Debit. The reverse is not necessarily true. Up until lately, Aldi would only accept debit cards (credit cards have higher merchant fees), and when I used to got to Sam's Club, they would accept Visa debit, but not credit (they had/have an exclusive deal with Discover for credit). So, yes, they can tell from the card number whether it's credit or debit. However, I've never heard of a case of the situation being biased against debit.*  That said there are some advantages to having a credit card: ETA: I don't know how credit history works in the EU, but in the US having open credit accounts definitely does affect your credit score which directly affects what rate you can get for a mortgage.  *ETA_2: As mentioned in the comments and another answer, car rentals will often require credit cards and not debit (Makes sense to me that they would want to make sure they can get their money if there is damage to the car). Many credit cards do include rental car insurance if you use it to pay for your rental, so that's another potential advantage for credit cards.
