Loan against credit card is a kind of personal loan. If you are using a credit card, you can easily apply for an instant loan against your card. The only difference between a personal loan and a loan against credit card is that a Personal Loan takes a couple of day to get approved while a loan against credit card is pre-approved. Unlike a personal loan, a loan against credit card does not require documentation. 

Normally, a bank asks for the following documents when you apply for a credit card:

• A copy of your address proofs such as recent electricity bill, telephone bill, driving license, passport etc. (Any of these documents).
• A proof of your identity such as PAN card, voter ID card, driving license, passport etc. (Any of these documents).
• A few recent passport size photographs.
• Last 3 months’ salary slips for salaried employees.
• A copy of office ID card – for salaried employees.
