4. Debit/Credit Cards
There is no doubt in the fact that the debit and credit cards have made our lives easier. Earlier when there were no such cards, cash or check remained the only mode of payment. However, now with the innovation of these cards, life has taken a faster route and you can pay up faster without having to wait for change. The first credit cards came as early as 1920 and today they have become an indispensable part of our lives.
