This market in credit guarantees is more developed in the USA (where credit cards have overtaken cash and personal checks as a mode of payment) than in Western Europe. But even in Europe there are credit card equivalents which are very widespread: the Eurocheck card, for instance, is really a credit card, though it usually comes with physical checks and guarantees only a limited amount. One must differentiate the functions of a debit card (with direct and immediate billing of a bank account following a transaction) from those of a credit card. The latter allows for the billing of the account to take place in a given day during the month following the month in which the transaction was effected or converts the payment into a series of instalments (within the credit limits of the cardholder as approved by his bank). But in both cases, the guarantee is there and is the most predominant feature of the system. Such cards seem like a perfect solution but they are not: the commissions charged by the card issuers are outrageous. Between 2 and 10 percent of the payment made go to the pockets of the card issuers. Cards get stolen, forged, lost, abused by their owners, expire. But with the advent of new technologies all these problems should be solved. Electronic POS (point of sale) cash registers, connected through networks of communication, check the card and verify its data: is it valid, is it presented by the lawful owner, was it stolen or lost, is the purchase within the limits of the approved credit and so on. Then, the billing proceeds automatically. Such devices will virtually eliminate fraud. The credit card companies will guarantee the payments, which will be subject to residual crime. Another fast developing solution is the smart card. These are cards similar to phone cards and they can be charged with money in the bank or through automatic teller machines. These cards (in wide use in Belgium, Austria, Germany and many other countries) contain an amount of money, which is deducted from the cardholders account. The account is billed for every recharge. The card is the electronic (and smart) equivalent of cash and it can be read (=debited) by special teller machines in numerous businesses. When payment is made, the money stored in the card is reduced and the recipient of the payment stores the payment on magnetic media for later delivery to his bank (and crediting of his account). A more primitive version exists in many countries in Eastern Europe: depositors receive checks exactly corresponding to the amount of money deposited in their account. These checks are as safe as the banks that issued them because they are fully convertible to cash. They are, really, paper "smart cards".
