Supplementary cards aren’t just for spending; some of them pack excellent travel and dining benefits too. Here are the best options to offer your family and loved ones.
Supplementary cards are a great way of extending credit facilities to family members and loved ones who may not otherwise qualify.
In one sense, a supplementary card is like cloning your main card. The supplementary cardholder can then make online or in-person transactions in Singapore or overseas, earning additional rewards for the main cardholder, while paying a reduced or waived annual fee.
But not everything is cloned! if you as the main cardholder receive lounge benefits, for instance, those may not necessarily be extended to supplementary cardholders as well.
So which supplementary cards offer actual, concrete benefits?

Supplementary card basics
Before we talk about the supplementary cards with the most perks, let’s do a quick rundown of some ground rules.
The first and most important thing to know is that principal cardholders are ultimately responsible for any spending made on their supplementary cards.
At the end of the month, the bank does not send a separate bill to the supplementary cardholder; instead, the principal cardholder gets one consolidated bill with all the spending made across principal and supplementary cards. This means that you should only issue a supplementary card to someone you’re confident will use it responsibly!
Second, since supplementary cardholder spending is the responsibility of the principal cardholder, spending across principal and supplementary cards is combined when determining whether the minimum spend for a sign-up bonus has been met.
For example, if a sign-up bonus requires a minimum spend of S$2,000, this can be achieved by the principal cardholder spending S$1,500 and the supplementary cardholder spending S$500. If you think you’ll have difficulty meeting a sign-up bonus through your own spending, a supplementary card allows you to “team up” with a second player.
Third, since supplementary cardholders are not ultimately responsible for the spending on their card, supplementary cards have no impact on their credit score. In other words, it neither helps nor harms an individual looking to apply for a principal card of their own.
Fourth, supplementary cardholders do not enjoy their own bonus caps. For example, the DBS Woman’s World Card earns 4 miles per S$1 on online spending, capped at S$2,000 per calendar month. Getting a supplementary card will not double this cap; instead, the supplementary cardholder will share the bonus cap of the principal cardholder.
Fifth, holding a supplementary card, in and of itself, does not disqualify you from the various new-to-bank promotions offered by banks and SingSaver. For example, holding a supplementary Citi PremierMiles Card does not render me ineligible to enjoy new-to-bank gifts when I apply for a principal Citi card myself.
Sixth and finally, supplementary cardholders must be aged at least 18, although exceptions can be made for individuals requiring a card for overseas travel.

Supplementary cards with the best perks
For the rest of this article, we’ll explore which supplementary cards offer the best perks and benefits.
As a general pointer, you may notice that all the cards below are for those who earn at least S$120,000 per annum. If you’re looking for meaningful benefits, you won’t find them with credit cards at the MAS-mandated minimum of S$30,000 per annum. At that level, supplementary cards at best receive the usual generic bank discounts. Unfortunately, that’s just the way things are.

While the vast majority of supplementary cards do not offer any benefits beyond another way of charging spend to the main cardholder, there is a small handful which offers travel, dining and lifestyle perks.
Keep in mind that these are invariably the more premium cards where annual fees cannot be waived (for the principal cardholder at least). However, offering supplementary cards to your loved ones allows you to tap additional benefits, thereby making the annual fee more worthwhile!
