As someone who doesn't spend much, is it worthwhile getting a credit card or should I just stick to a debit card?

Guess we are in the same consumer category as far as spending goes. Debit cards have worked for me all through, which has helped keep me out of unnecessary debts.

​

Thus, I will advise that you stay away from credit cards unless you run into an emergency situation which requires compulsory (not compulsive) borrowing.

Yes.

1. Build credit score
2. Have transaction security
3. Cashflow management
4. Credit card perks

Debit card is immediate money out of account.
Call to cancel credit card or transaction if any fraud case.
Allows you to delay payment for 20 days and can also take loan against credit card, if need be.
