Everything You Need to Know About Add-on Credit Cards: Benefits, How They Work & How to Apply

What Are Add-on Credit Cards?
An add-on card is a supplementary credit card issued to a family member based on an existing primary credit card. The add-on card shares the same credit limit and benefits as the primary cardholder.

How Do Add-on Cards Work?

  • They function just like the primary credit card for transactions
  • All add-on card expenses are consolidated into the primary card’s bill
  • The primary cardholder is responsible for paying the full bill
  • No separate credit limit—all cards share the same credit limit

How to Apply for an Add-on Card?

  • Most banks allow 2-3 add-on cards per primary card (some may allow more).
  • Apply online via net banking or mobile banking OR visit the branch.
  • Required documents: KYC, photograph, proof of relationship.
  • Add-on cards are typically issued only to immediate family members (spouse, children, parents, siblings).
  • Minimum age: 18 years for most banks.

Benefits of Add-on Credit Cards

  • Financial freedom for family members without a credit score
  • Earn reward points on eligible spends like the primary card
  • Contribute to milestone spends, annual fee waiver, and lounge access
  • Some premium cards like HDFC Diners Black & Infinia offer lounge access to add-on cardholders
  • Set limits & control spends via net banking

How to Manage Add-on Cards?

  • The primary cardholder can enable/disable transactions on the add-on card
  • Set spending limits or restrict international transactions
  • The primary cardholder’s credit score is affected if the bill isn’t paid on time
