What is the Meaning & Definition of credit card

The concept of credit card is one very recent if you consider that it comes at the beginning of the 20th century. When we speak of magnetic card we talked about a small plastic card that has a magnetic strip and a system of numbers and identifying data to determine owner, time of issue and other elements. The main function of the credit card is the allow a person to do different shopping or consumption shares without having to pay in cash and may, in addition, take payment of the products to future periods. Credit cards are perhaps one of the most important and characteristic in the economic and financial field of the 20th century. The most primitive forms of credit cards as we know them today were those who began to spread among some companies of different products in the United States in the 1920's. These cards were for internal use in such companies and were used to certify salary and perform other simple operations, although not yet for consumption. One can say that the presence of credit cards is typical of an era in which finance and speculation about the financial system were to be speak of silver or capital that were not specifically if not speculative.
Today, credit cards and its derivatives as the debit cards, cards for discounts or promotions, are all important elements in national and international economies as awarded to individuals many facilities when making different purchases or actions of consumption. Credit cards often have an imaginary boundary of silver that allows the person to buy or consume services and goods up to that previously established amount (in which case the card is disabled). The convenience of cards allows that a person can continue eating even when you don't have cash in hand, provided he undertakes to pay him regularly in the near future.
