Hi @Raj Sharma
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
You can remove your credit card from your Azure account. However, if the credit card is the active payment method for any of your subscriptions, you will need to change the active payment method before you can delete it.
Once you remove your credit card, you will still be able to use the Azure services as long as you have an active subscription, but you may need to add a new payment method if you want to continue using paid features in the future.
