All You Need to Know About Supplementary Credit Cards

A supplementary credit card, also known as an add-on credit card, is an additional card issued on a primary card account and can be extended to the primary cardholder’s family members.

The supplementary cardholder can use the card to make purchases online and offline, just like any other card. However, all spends are linked to the primary account and the primary cardholder receives a consolidated statement of both the primary and supplementary card. The primary user retains complete ownership of the account and is solely responsible for making bill payments.

Let us understand the features of supplementary credit cards in some detail:

Separate Card, Shared Account

The supplementary cardholder receives a separate physical card that has their name but it shares the primary cardholder's credit account.

Shared Credit Limit

The supplementary card uses the same overall credit limit as the primary card unless the issuer allows a separate spending limit to be assigned and the primary cardholders set a limit.

Consolidated Monthly Statement

Transactions made using both cards appear in a single monthly statement, making expense tracking easier.

Shared Rewards

Purchases made through the supplementary card usually earn reward points, cashback or miles at the same rate as the primary card. These points are credited to the primary cardholder's account.

Same Card Benefits

Depending on the issuer, supplementary cardholders may enjoy several benefits available on the primary card, such as airport lounge access, dining privileges or insurance covers.

Some of the key benefits of supplementary credit cards are given below:

Extending Card Benefits to Family Members

Instead of sharing one physical card, each eligible family member can have their own supplementary card issued in their name, while expenses remain under one account.

Faster Reward Accumulation

Since transactions from both primary and supplementary credit cards are combined to earn reward points, cashback or travel miles, the value-back can be higher due to faster reward accumulation.

Better Expense Tracking

Spends made by different family members is reflected in one statement, which makes it easier to monitor household expenses.

Emergency Financial Support

A supplementary card can provide family members with access to funds during emergencies – even to those who may not be eligible to get a primary card for themselves.

Access to Premium Benefits

Some credit cards, especially premium ones, extend perks to supplementary cardholders. This may include complimentary access to airport lounges, dining discounts or travel privileges.

Financial Independence with Supervision

Parents can provide a supplementary card to adult children while maintaining visibility and control over spending.

Most banks allow supplementary credit cards to be issued to immediate family members. However, the exact eligibility criteria vary across issuers.

Typically, supplementary cards can be issued to the parents, children or spouse of the primary cardholder. Children meeting the minimum age requirement specified by the bank.

Some banks may also permit supplementary cards for other relatives, subject to their policies.

A supplementary credit card may be suitable for:

• Couples who manage household expenses together
• Parents who wish to provide controlled spending access to children
• Individuals supporting elderly parents with day-to-day expenses
• Frequent travellers who want family members to enjoy selected travel benefits
• Households seeking better expense management under one account

Before applying for a supplementary credit card for your family member, you must consider the following points:

• The primary cardholder remains responsible for all dues, regardless of who made the purchases.
• Spending by the supplementary cardholder reduces the shared credit limit available to the primary cardholder.
• Missed payments can impact the primary cardholder's credit profile.
• Some issuers charge an annual fee for supplementary cards.
• Not all benefits available on the primary card may extend to supplementary cards.
