Best supplementary credit cards

Supplementary credit cards are like the sidekick to the superhero primary credit cards. They offer a convenient way to share one's credit card benefits with others, like family members or friends, without them having to apply for their own card.

Who are supplementary credit cards suitable for?

  • Couples. Combine spending on a single account to earn more credit card reward points.
  • Parents. Issue supplementary cards for the kids and monitor their spending.
  • Families. Use supplementary cards to simplify the family's finances with the same credit card account.

What to compare for supplementary credit cards

  • Rewards. If you're considering a new credit card that earns points, will the supplemental card have the same earn rate?
  • Perks. Will the supplemental cardholders have access to the same mouth-watering benefits as you do on the primary one?
  • Fees. Is there a fee per supplementary card, or is it free to add additional cards? If there is a fee, it can add up quickly. Note that just because a credit card has no annual fee does not automatically mean supplementary cards are free.
  • Credit limits. Can you specify a credit limit for the supplementary card?
  • Eligibility. Who can you give an additional card to? How many can you get?

How to compare credit cards with supplementary cards

  1. Compare rewards and benefits across various cards to find the most attractive credit card offers.
  2. Look for any fees associated with supplementary cards, which may vary between card issuers.
  3. Check the credit limit structures. Do they offer individual or shared limits?
  4. Assess eligibility criteria and make sure you aren't going to apply for something you can't get.
  5. Get your documents together and submit your application. Online is the fastest. Myinfo makes it even easier.
  6. Activate the main card when they are delivered, then add the supplementary cardholders.

Pros and cons

Pros

  • Earn rewards faster. Spending with supplementary cards means more reward points.
  • Easier financial management. Monitor family finances with ease.

Cons

  • Risk of overspending. Supplementary cardholders — who are your responsibility — could spend recklessly.
  • Credit score damage. Potential negative impact on the primary cardholder's credit report if mismanaged.
  • Supplementary cardholders don't build credit. This is because they are not the main name on the account.
  • Supplementary cardholders don't collect points. Any points or cashback go to the main cardholder.

FAQs

What is the difference between a primary and supplementary credit card?

A primary credit card is issued to the cardholder who applies for it. A supplementary card is an additional card linked to the same account that a primary cardholder can provide to a loved one or friend.

Who is responsible for the charges on a supplementary credit card?

The primary cardholder is responsible for any charges made on a supplementary credit card. Transactions made with the supplementary card are consolidated into the primary cardholder's account.

Do supplementary cardholders build credit?

No. Supplementary cardholders will not build credit using a supplementary card. Only the primary name on the account will build credit (or have their credit impaired if they mismanage the account).

How do I apply for a supplementary credit card?

Applying for a supplementary credit card typically requires the primary cardholder to fill out an application form with the prospective supplementary cardholder's personal details, which is then submitted to the bank for approval.
