Paying or transferring debt from one lender to the other is called a balance transfer. This involves transferring part or all of the debt from a credit card with one lender to a credit card with another. As part of the process, your new lender will pay out the old lender, so that you now owe the same amount of money but to a new institution.
Many credit card providers offer an interest-free period on balance transfers to help new applicants better handle their debt. During this period, cardholders are not required to pay interest on the debt they brought over from the other card. This can be a great opportunity for consumers to pay off credit card debt with no interest. There are often fees associated with balance transfers; normally, these are a percentage of the amount transferred.
So make sure you read the terms and conditions of the card before transferring any debt across.
