All too many consumers are finding that they are paying a great deal in interest on their credit cards even though they have limited their spending considerably.  Their previous balances are coming back to haunt them with high interest rates and monthly payments.  These customers often don't know that they do have other options in the form of balance transfer cards.  These cards offer them the opportunity to transfer their high interest balances to one with little or no interest for a set time frame. 
Balance transfer cards can be invaluable to some while seeming pointless to others.  Discussed here would be situations where balance transfer cards will be beneficial to the consumer.
If you have things you want or need to purchase but are holding back because of the high interest on your current credit card, a balance transfer may be a good option.  Also, if you are finding you never use the card or your current card has expired then essentially you have nothing to lose with obtaining a new one.  When looking for a balance transfer card, the goal is to find one with zero interest on balance transfers for the longest period of time possible.  Balance transfer cards usually have a six to eighteen month term with promotional interest to captivate new customers.
There are several things consumers should know before signing up for a balance transfer card.  To begin with, customers should know that there is typically a fee charged for transferring a balance.  The fee is usually dependant on the transfer amount being a few percent.  Although it seems unwise to add to your debt, the lower or lack of interest will justify the transfer fee in very little time.  Just be certain that the transfer fee doesn't put you over the limit of what you are able to pay.
You would also need to be absolutely sure you can make the minimum payments each month in a timely manner.  Promotional zero interest offers are most likely terminated if you do not meet this requirement.  If this happens, you may be left in the same or worst situation compared to before the balance transfer.
Finally, it is important to know that the promotional zero interests apply only to the balance transfer and not to any additional debt you acquire with the card.  Using the card for further purchases or cash withdrawals is highly ill-advised.
