This varies a lot between countries and cultures.

For example in New Zealand, EFTPOS cards are very popular (similar to debit cards, but issued directly by our banks so no user fees ever - the merchant pays for the machine and that's it). People usually have all 3 - an EFTPOS card for most in-person purchase (although online EFTPOS is gaining adoption), a debit card for online or paywave-only places, and a credit card for large purchases/ emergencies. Credit cards here are highly unpopular among the under-25 age bracket; most young people just have EFTPOS and debit.

I think this might be a result of our stricter banking regulations compared to economies like the U.S.; it's difficult for banks to offer tempting enough rewards schemes to entice people to credit cards. Additionally, there is much less of a borrowing culture - most people will only ever properly borrow money once - buying a house. Paying cash for cars is the norm, and purchasing anything else on finance is seen as stupid compared to just saving the money (and earning the interest yourself).
