Historia del dinero

The History of Money
It has been a central part of our lives and our civilizations for more than 4,000 years.
Money. And over this expanse of human history, the physical form money has taken has evolved from
seashells to digital bits of data
Before there was money
It's hard to think of a world without money. But for most of human history, money had not existed.
The earliest human societies didn't need money. Instead, goods were bartered or traded.
Bartering is our earliest form of payment an original substitute for money. However, barter only worked when
both parties wanted the goods of offer for exchange.
As societies developed and commerce became more complex, a new way around these problems was needed.
The Cowry shell
The oldest written records of money come 4,500 years ago from ancient Mesopotamia, now known as
southern Iraq. About 3,500 years ago tiny Cowry shells from the Indian Ocean were used in China as a means
of exchange. Even the Chinese symbols used today for buying, bartering and selling incorporate the symbol
for the Cowry shell.
These shells were still being used as accepted currency in parts of Africa as late as the 19th century.
From silver to the first coins
Ancient Mesopotamian inscriptions describe payments being made with weighed amounts of silver. Since
then, weighed amounts of metal have been used as money in many parts of the world, and this practice led to
the invention of coins.
Coins are just pieces of metal marked with a special design that indicates its use as money. Unlike precious
metals, however, coins do not need to have an intrinsic value in themselves. They only represent a token of
value.

True coinage developed in Asia Minor during the 7th century BC in what is now Turkey.
Weighed lumps of 'electrum' a mixture of gold and silver were used by the Lydians as money. The Lydians
stamped their lumps of electrum with various images a practice known as minting to guarantee their purity
and authenticity. These irregular lumps were eventually standardized in shape and weight.
The same idea was simultaneously developed elsewhere, albeit using different metals. Copper lumps were
used in both what are now Southern Russia and Italy, bronze used in China, silver rings in Thailand, and gold
and silver bars in Japan.
As soon as coins became commonplace, however, people realized their limitations chiefly their weight and
bulk. And, as trade began to take on a less regional and more international perspective, a new type of money
was needed to make larger transactions easier.
The emergence of banks and banknotes
During the 10th century, the Chinese began the process of depositing their heavy iron coins with local
merchants in return for hand written receipts. The holder of these receipts would then use them to purchase
goods from the merchant when needed. This system acted as an early version of pre−paid commerce.
The Chinese government, who issued the iron coins, adopted the paper receipt system in the early 11th
century, printing receipts with fixed face values. Soon, this practice evolved and spread, with gold and silver
as well as coins being deposited often with Goldsmiths in exchange for paper receipts.
The goldsmiths profited from the gold, silver and iron coin deposits by lending these valuable items out to
third parties in return for interest charged. Eventually banks emerged, assuring the value of notes they issued
into circulation. Incidentally, the first banks exchanged notes for coins and precious metals on benches, and
this is where the term bank comes from: banco is the Italian word for bench. But it was the Swedish
Stockholm Bank that issued the first official printed notes in 1661.
Notes soon replaced the old pre−paid paper receipt system and banknotes had become the common form of
public currency.
Forgery and the frequency of issuers going out of business led to the practice of governments taking over the
issuance of notes and coins. Gold and silver reserves were used to back up the value of the currency issued
and these reserves were stored in highly guarded and fortified places, such as England's Tower of London.
However, even banknotes soon demonstrated their limits. Governments soon discovered that printing and
circulating cash and storing and protecting the reserves that secured the value of the cash issued into
circulation was both expensive and risky: Paper currency in particular was prone to loss due to fire, moisture
and perhaps the greatest peril to the system forgery. Soon banks sought out better currency systems than paper
money.

Cheques and Plasticthe Dawn of the Modern Age of Money
The use of cheques, printed by issuing banks, brought back the practice of paper receipts, but this time the
exchange notes were used as post−payment rather than as pre−payment. Cheques were used between one
individual and another, between a consumer and a merchant, between merchants and even between banks.
This new system allowed money to change hands without the need for exchanging actual bank notes or coins.
Over the past twenty years, with the advent of computers and international telecommunications, most of the
world's transactions are conducted digitally. Value is transferred from one account to another, from one bank
to another without the need for exchanging bills and coins physically.
Plastic cards holding personal data on magnetic stripes were developed to give people virtual access to their
money. Today, debit and credit cards, along with cheques, linked to the user's bank account enable nearly
every kind of payment.
As with all previous stages in the evolution of money, however, even cheques and plastic cards have their
limitations. For example, debit and credit cards require telephone lines, third party authorizations, signatures
and PIN codes, all slowing down the transaction process and limiting the places where such transactions can
take place. Furthermore, the infrastructure required to facilitate their use is expensive. Using a credit card to
make a ten−cent purchase is just not cost effective.
Notes and coins are still the most suitable means of making small everyday payments.
Today, money is evolving to its next stage one that combines the convenience of plastic with the flexibility
and cost−effectiveness of cash. This newest stage in the evolution of money is electronic cash.
Electronic Cash and Smart Cards: A Payment Solution for the 21st Century
Despite the popularity of credit and debit cards, the vast majority of all transactions worldwide are still carried
out with cash.
Cash remains the only universally acceptable form of payment. Even when a retailer doesn't accept a
particular credit card, cash will be taken. When it is, the exchange of value is immediate: No clearing or
processing is needed, no signatures and no electronic transfers required.

A true cash alternative, replicating the core features of notes and coins, would have to be universally
recognized and accepted. Like cash, transactions would have to offer immediate transfers of value and must
enable easy person−to−person payments.
Electronic cash must also be able to work in different currencies and would have to be secure from forgery
and malfunction.
