There is fare hike coming at the end of the year! Save on your public transportation rides when you pay for your fares with these credit cards. Cashback Banks tend to be disingenuous with cashback earn rates, so I have put a Maximum Earn Rate column next to the advertised rate. UOB One, for instance, advertises a 10% earn rate for public transportation rides, but you would often earn a mere 3.33% for most other spend, decreasing your effective cashback yield a fair bit. If you meet the minimum spend solely on bus/train rides, your effective yield is 8.33%. Of course, no one spends that much on public transportation in a month, and I have placed a Realistic Earn Rate column to show what spending $100 a month on these cards would look. Note that you also have to fulfil the minimum spend and spend conditions (if any) on almost all of these cards....
