When applying for credit cards, it's important to shop around. Fees, charges, interest rates and benefits can vary drastically among credit card issuers. And, in some cases, credit cards might seem like great deals until you read the fine print and disclosures. It's important to pay close attention to the fine details of each credit card. Here are some important details to keep in mind:

Annual percentage rate (APR): The APR is a measure of the cost of credit, expressed as a yearly interest rate. The lower the APR, the better for you. Be sure to check the fine print to see if your offer has a time limit. Your APR could be much higher after the initial limited offer expires.

Grace period: This is the length of time between the date of the credit card purchase and the date the company starts charging you interest. Some companies have eliminated grace periods, which means you could start paying interest literally from the minute you make a purchase. The longer the grace period, the better the deal is for consumers.

Annual fees: Many credit card issuers charge an annual fee for giving you credit, typically $15 to $55. However, there are many other cards that have no annual fees, but with a trade-off in other areas.

Application or approval fees: This is a one-time fee that is immediately charged to your card upon approval. Most credit cards these days don't charge application fees, but it isn't unheard of to see these fees go as high as $250.

Transaction fees and other charges: Most creditors charge a fee if you don't make a payment on time. Other common credit card fees include those for cash advances and going beyond the credit limit. Moreover, some credit cards charge a flat fee every month, whether you use your card or not.

Each credit card varies, but it is up to you which best fits you and your credit abilities and needs. Do not be lured into getting credit cards based on ten or twenty percent discounts for signing up for one at a department store or for signing up if you get a free T-Shirt or an extra 1,000 frequent flier miles. And make sure you only invest in a credit card(s) if you have a job and/or a regular income and are capable of paying off your credit cards in a timely manner without getting hit hard by interest rates.
