HOW THE CREDIT CARD CAPTURED AMERICA
The proliferation of platinum American Express cards in the 1980s spawned rumors of an ultimate, highly exclusive, never publicized "Black Card". Carried by billionaires, it reportedly allowed holders to demand private shopping sprees at the world's most exclusive shops and to summon helicopters in the middle of Sahara. American express vehemently denies the existence of such a charge card. But the persistence of the myth suggests the social importance credit cards have for so many Americans. As one business writer puts it, "to have one's credit cards canceled is now akin to being excommunicated by the medieval church."
America's love affair with the credit card began in 1949, when businessman Frank X. McNamara finished a meal in a New York restaurant and then discovered he had no cash. In those days, gasoline and store charge cards were common, but cash was standard for almost everything else. The embarrassed McNamara called his wife, who rushed over to bail him out. His predicament gave him the idea for Diners Club. Within a year some 200 people carried the world's first multi-use credit card.
The problem was to persuade enough people to carry the cards. Diners Club turned to promotions. It gave away a round-the-world trip on a popular television show. The winners charged their expenses and made it "from New York to New York without a die in their pockets".
Banks, sensing among less affluent a pent-up desire to spend, began issuing cards of their own. The first to turn a profit was Bank of America's Bank Americard. Bankers from all over the country descended on its California headquarters to learn the secret of its success--so many that in 1966 Bank Americard, today known as Visa, began forming alliances with banks outside the state. The Bank Americard network soon faced a competitor when Wells Fargo Bank joined with 77 others to create what became Master Charge. After scooping up 1.3 million more "Everything Card" holders from what was then First National City Bank, Master Charge--today's Master Card--became for a while the biggest bank card in the country.
Five million holiday credit-card shoppers would have created a bonanza for the banks, but in the rush to market, the hanks had been less than cautious in assembling their lists. Some families received 15 cards. Dead people and babies got cards. Even a dachshund named Alice Griffin was sent one that promised she would be welcomed as a "preferred customer" at Chicago's finest restaurants.
Hundreds of Chicagoans discovered they could use or sell a car they "found", and by law, the person whose name appeared on it was liable for the charges--even if he or she had never requested or received the card.
When the prime rate hit 20% in 1981, the banks found that consumers didn't mind paying rates of 18--22% on their credit-card balance. High interest rates helped attract new players into the credit-card area, including sears' Discover Card and Visa. Airlines, car and insurance companies, even long-distance phone companies allied themselves with banks to offer credit cards. Experts estimate there are from 15, 000 to 19, 000 different cards available in the country.
Of course, credit cards have not only replaced cash for many purposes, but also in effect have created cash by making it instantly available virtually everywhere. The credit-card advance is becoming as ubiquitous as the automated teller machine.
