cashless system

In a cashless society, financial transactions are not conducted with physical banknotes or coins, but instead with digital information (usually an electronic representation of money). Cashless societies have existed from the time when human society came into existence, based on barter and other methods of exchange, and cashless transactions have also become possible in modern times using credit cards, debit cards, mobile payments, and digital currencies such as bitcoin.
Such a concept has been discussed widely, particularly because the world is experiencing a rapid and increasing use of digital methods of recording, managing, and exchanging money in commerce, investment and daily life in many parts of the world, and transactions which would historically have been undertaken with cash are often now undertaken electronically. Some countries now set limits on transactions and transaction values for which non-electronic payment may be legally used.
