Credit Card Info

A credit card system is a type of retail transaction settlement and credit system, named after the small plastic card issued to users of the system. A credit card is different from a debit card in that the credit card issuer lends the consumer money rather than having the money removed from an account. It is also different from a charge card (though this name is sometimes used by the public to describe credit cards) in that charge cards require that the balance be paid in full each month. In contrast, a credit card allows the consumer to 'revolve' their balance, at the cost of having interest charged. Most credit cards are the same shape and size, as specified by the ISO 7810 standard.

How they work

user is issued a credit card after an account has been approved by the credit provider (often a general bank, but sometimes a captive bank created to issue a particular brand of credit card, such as American Express Centurion Bank), with which he or she will be able to make purchases from merchants accepting that credit card up to a preestablished credit limit.

When a purchase is made, the credit card user agrees to pay the card issuer. Originally the user would indicate his/her consent to pay, by signing a receipt with a record of the card details and indicating the amount to be paid, but many merchants now accept verbal authorizations via telephone and electronic authorization using the Internet.

Electronic verification systems allow merchants (using a strip of magnetized material on the card holding information in a similar manner to magnetic tape or a floppy disk) to verify that the card is valid and the credit card customer has sufficient credit to cover the purchase in a few seconds, allowing the verification to happen at time of purchase. Other variations of verification systems are used by eCommerce merchants to determine if the user's account is valid and able to accept the charge.

Each month, the credit card user is sent a statement indicating the purchases undertaken with the card, and the total amount owed. The cardholder must then pay a minimum proportion of the bill by a due date, and may choose to pay the entire amount owed or more. The credit provider charges interest on the amount owed (typically at a much higher rate than most other forms of debt). Some financial institutions can arrange for automatic payments to be deducted from the user's accounts.

Credit card issuers usually waive interest charges if the balance is paid in full each month, but typically will charge full interest on the entire outstanding balance from the date of each purchase if the total balance is not paid.

For example, if a user had a $1,000. outstanding balance for purchases and pays the entire $1,000. there would be no interest charged. If, however, even $1.00 of the total balance remained unpaid, interest would be charged on the full $1,000 from the date of purchase until the payment is received. The precise manner in which interest is charged is usually detailed in a cardholder agreement which may be summarized on the back of the monthly statement.

The credit card may simply serve as a form of revolving credit, or it may become a complicated financial instrument with multiple balance segments each at a different interest rate, possibly with a single umbrella credit limit, or possibly with separate credit limits applicable to the various balance segments. Usually this compartmentalization is the result of special incentive offers from the issuing bank, either to incent balance transfers from cards of other issuers, or to incent more spending on the part of the customer. In the event that several interest rates apply to various balance segments, payment allocation is generally at the discretion of the issuing bank, and payments will therefore usually be allocated towards the lowest rate balances until paid in full before any money is paid towards higher rate balances. Interest rates can vary considerably from card to card, and the interest rate on a particular card may jump dramatically if the card user is late with a payment on that card or any other credit instrument. As the rates and terms vary, services have been set up allowing users to calculate savings available by switching cards, which can be considerable if there is a large outstanding balance (see external links for some on-line services).

Because profit margins in the credit card industry can be quite high, credit providers often offer incentives such as frequent flier miles, gift certificates, or cash back (typically 1 percent) to try to attract customers to their program.

Low interest credit cards or even 0% interest credit cards are available. The only downside to consumers is that the period of low interest credit cards is limited to a fixed term, usually between 6 and 12 months. However, services are available which alert credit card holders when their low interest period is due to expire. Most such services charge a monthly or annual fee.

The merchant's side

For merchants, a credit card transaction is often more secure than other forms of payment, such as cheques, because the issuing bank commits to pay the merchant the moment the transaction is verified. The bank charges a commission (Interchanging Fee), to the merchant for this service and there may be a certain delay before the agreed payment is received by the merchant. In addition, a merchant may be penalized or have their ability to receive payment using that credit card restricted if there are too many cancellations or reversals of charges.

Secured credit cards

A secured credit card is a type of credit card secured by a deposit account owned by the cardholder. Typically, the cardholder must deposit between 100% and 200% of the total amount of credit desired. Thus if the cardholder puts down $1000, he or she will be given credit in the range of $500–$1000. In some cases, credit card issuers will offer incentives even on their secured card portfolios. In these cases, the deposit required may be significantly less than the required credit limit, and can be as low as 10% of the desired credit limit. This deposit is held in a special savings account.

The cardholder of a secured credit card is still expected to make regular payments, as he or she would with a regular credit card, but should he or she default on a payment, the card issuer has the option of recovering the cost of the purchases paid to the merchants out of the deposit.

Although the deposit is in the hands of the credit card issuer as security in the event of default by the consumer, the deposit will not be credited simply for missing one or two payments. Usually the deposit is only used as an offset when the account is closed, either at the request of the customer or due to severe delinquency (150 to 180 days). This means that an account which is less than 150 days delinquent will continue to accrue interest and fees, and could result in a balance which is much higher than the actual credit limit on the card. In these cases the total debt may far exceed the original deposit and the cardholder not only forfeits their deposit but is left with an additional debt.

Most of these conditions are usually described in a cardholder agreement which the cardholder signs when their account is opened.

Secured credit cards are an option to allow a person with a poor credit history or no credit history to have a credit card which might not otherwise be available. They are often offered as a means of rebuilding one's credit. Secured credit cards are available with both Visa and MasterCard logos on them. Fees and service charges for secured credit cards often exceed those charged for ordinary non-secured credit cards, however, for people in certain situations, (for example, after charging off on other credit cards, or people with a long history of delinquency on various forms of debt), secured cards can often be less expensive in total cost than unsecured credit cards, even including the security deposit.

Features

As well as convenient, accessible credit, the cards offer consumers an easy way to track expenses, which is necessary both for monitoring personal expenditures and the tracking of work-related expenses for taxation and reimbursement purposes. They have now spread worldwide, and are offered in a huge variety of permutations with differing credit limits, repayment arrangements such as automatic payment from a personal bank account (some cards offer interest-free periods, while others do not but compensate with much lower interest rates), and other perks (such as rewards schemes in which points earned by purchasing goods with the card can be redeemed for further goods and services or credit card cashback).

Some countries such as the United States and the United Kingdom limit the amount for which a consumer can be held liable due to fraudulent transactions as a result of a consumer's credit card being lost or stolen.

Security

The low security of the credit card system presents countless opportunities for fraud. This opportunity has created a huge black market in stolen credit card numbers, which are generally used quickly before the cards are reported stolen.

The goal of the credit card companies, as they say, is not to eliminate fraud, but to "reduce it to manageable levels", such that the total cost of both fraud and fraud prevention is minimized. This implies that high-cost low-return fraud prevention measures will not be used if their cost exceeds the potential gains from fraud reduction.

Most Internet fraud is done through the use of stolen credit card information which is obtained in many ways, the simplest being copying information from retailers, either online or offline. There have been many cases of crackers obtaining huge quantities of credit card information from company databases. It is not unusual for employees of companies that deal with millions of customers to sell credit card information to criminals^{[citation needed]}.

Despite efforts to improve security for remote purchases using credit cards, systems with security holes are usually the result of poor implementations of card acquisition by merchants. For example, a website that uses SSL to encrypt card numbers from a client may simply email the number from the webserver to someone who manually processes the card details at a card terminal. Naturally, anywhere card details become human-readable before being processed at the acquiring bank is a security risk. However, many banks offer systems such as ClearCommerce, where encrypted card details captured on a merchant's webserver can be sent directly to the payment processor.

The Federal Bureau of Investigation is the agency responsible for prosecuting criminals who engage in credit card fraud in the United States, but they do not have the resources to pursue all criminals. In general, they only prosecute in cases exceeding $5,000 in value. Even though the FBI usually does not investigate, most common credit card networks have not implemented procedures to prevent credit card fraud. ^{[citation needed]} Three improvements to card security have been introduced to the more common credit card networks but none has proven to help reduce credit card fraud so far. First, the on-line verification system used by merchants is being enhanced to require a 4 digit Personal Identification Number (PIN) known only to the card holder. Second, the cards themselves are being replaced with similar-looking tamper-resistant smart cards which are intended to make forgery more difficult. The majority of smartcard (IC card) based credit cards comply with the EMV (Europay MasterCard Visa) standard. Third, an additional 3 or 4 digit code is now present on the back of most cards, for use in "card not present" transactions. See CVV2 for more information.
