SINGAPORE - Undergraduate Tay Bo Yi carries little cash in his wallet as he prefers the convenience of cards.
The Nanyang Business School undergraduate toggles between his debit and credit cards, to maximise his credit for the month.
Due to his heavy card usage, his pocket is full of online bank tokens - six to be exact - so that he can check his balances.
But Mr Tay, 23, is no big spender. At the age of 14, he already understood the idea of locking up his savings in a dedicated bank account, and having a separate one for expenditure.
The young saver, who lives in an HDB flat in Jurong, is largely influenced by his civil servant father who often gives him advice on money matters.
With his preference for credit cards, the marketing major who runs a small online business wants to learn more about how they work.
"I am interested in joining a bank and marketing credit cards. The use of credit cards is a win-win situation for banks, but not for merchants.
"Why is it that you use a card and you can get 10 per cent off spending, but don't when you use cash? I want to find out the mechanism behind this, and how banks make money from credit cards."
