Getting a new credit card will not fix your bad credit score in anyway and with a bad credit score, it is difficult to get a credit card from the lenders. However, if you still want to get hold of a credit card, you can get a secured credit card against your fixed deposit. 

This credit card will help you manage your finances effectively but won’t change your bad credit score. Poor credit score could be a result of past dues, negative accounts or errors in your credit report. To fix it, you need to get the credit report and analyse the grey areas. Once you have identified issue, you must act to resolve it.
