The best way of growing your miles balance, apart from sign-up bonuses, is to divert as much spend as you can to specialised spending cards.
It should be obvious why: specialised spending cards offer earn rates of 4 mpd, allowing you to earn your free flights much faster than general spending cards with their earn rates of 1.2-1.6 mpd.
But not all specialised spending cards are made the same. You may have come across the terms “blacklist policy” and “whitelist policy”, and wonder what it all means.
In short, blacklist cards reward modes of spending, while whitelist cards reward categories of spending. Modes is broader than categories, which makes blacklist cards more versatile and straightforward solutions.

That said, whitelist cards still have a role to play, and in this post we’ll see how to best optimise between both.

Let’s first start with blacklist cards, where the rule is very simple:
All transactions earn bonuses, unless they’re on the exclusions list
DBS Woman’s World Card
The DBS Woman’s World Card awards 4 mpd on all online transactions, except those on the DBS general exclusions list.
Citi Rewards Card
The Citi Rewards Card is a hybrid of blacklist and whitelist:
- For online transactions, it adopts a blacklist approach, awarding 4 mpd on all transactions except:
- For in-person transactions, it adopts a whitelist approach (see next section)
UOB Preferred Platinum Visa
The UOB Preferred Platinum Visa is also a hybrid:
- For in-person transactions, it adopts a blacklist approach, awarding 4 mpd on all mobile contactless payments (e.g. Apple, Google, Samsung or Fitbit Pay), except those on UOB’s general exclusion list
- For online transactions, it adopts a whitelist approach (see next section)
UOB Visa Signature
The UOB Visa Signature awards 4 mpd on all foreign currency, contactless and petrol transactions, except those on UOB’s general exclusion list.
When using this card, take care with how you calculate the S$1,000 minimum spend, which can be quite confusing to first-timers.

UOB Lady’s Cards
The UOB Lady’s Card and UOB Lady’s Solitaire Card allow cardholders to pick one and two bonus categories respectively from a list of seven options, including beauty & wellness, dining, entertainment, family, fashion and travel.
These can be rotated every calendar quarter, allowing the card to be different things to you at different times.

Mixing blacklist and whitelist cards
Because of their versatility, blacklist caps are inherently more valuable than whitelist caps.
It doesn’t matter what the MCC is (assuming it’s not on the general exclusions list, of course); so long as you pay via the prescribed method — online, contactless, in foreign currency, as the case may be — you’ll earn your bonuses.
The sum of monthly bonus caps on all blacklist cards comes up to S$5,610 a month. Assuming you’re the sort who regularly maxes out bonus caps, you should aim to preserve your blacklist cards’ more flexible caps by utilising whitelist cards’ caps first.
For example, if you’re buying something on Shopee, both the HSBC Revolution and DBS Woman’s World Card would earn 4 mpd. But since the HSBC Revolution is a whitelist card, and the DBS Woman’s World Card is a blacklist card, the smarter decision would be to use the former, and save the latter for other situations.
In that sense, whitelist cards’ bonus caps serve as a buffer that can be fully utilised before touching the blacklist cards’ bonus caps.
Blacklist cards are best used in situations where the merchant does not feature on any whitelist, such as car dealers, car servicing workshops, veterinarians, dentists, health screenings, teleconsultations, phone bills, streaming subscriptions, or furniture stores.
Blacklist cards can also be idiot-proof solutions you can give a spouse or family member who can remember every supporting characters’ name on their favourite Korean drama, but not what card to use at McDonald’s.
Conclusion
If you’re the sort who regularly busts bonus caps, the rule of thumb should be to draft in whitelist cards and utilise their caps first, only then switching to blacklist cards for non-whitelisted categories.
It does take a little more micromanagement, but it keeps you from having to put spend on general spending cards, or worse, a specialised spending card beyond its cap, where a dismal 0.4 mpd awaits.
How do you optimise spending among your whitelist and blacklist cards?
