An add-on credit card is literally a supplementary card that is issued under the main cardholder's account. Banks typically enable family members such as spouses, above-18-year-old children, or even parents to have these cards. The add-on card shares the same credit limit with the main card and the charges are consolidated into one statement. Despite being handy and providing wider access to credit, the onus of repayment remains only with the principal cardholder.

Benefits of add-on credit cards

Accessibility is among the biggest advantages. Add-on cards grant financial freedom to dependents, like college kids or elderly parents, without a secondary credit history or approval process. They also allow families to consolidate bills into an account, which makes it easy to track family expenditures. Most banks provide the same benefits—cashback, rewards points, and discounts—to supplementary card users, thus enabling families to earn rewards more quickly. Banks also sometimes forgo the joining fee or annual fee for a supplementary card, making them a cost-effective option.
