Cashless society

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. However, this article focuses on the term "cashless society" in the sense of a move towards a society in which cash is replaced by its digital equivalent—in other words, legal tender (money) exists, is recorded, and is exchanged only in electronic digital form. 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. Early ideas of a cashless society were expressed by Edward Bellamy in his novel Looking Backward. The trend towards the use of non-cash transactions and settlement in daily life began during the 1990s when electronic banking became common. By the 2010s digital payment methods were widespread in many countries, with examples including intermediaries such as PayPal, digital wallet systems such as Apple Pay, contactless and NFC payments by electronic card or smartphone, and electronic bills and banking, all in widespread use. At this point cash had become actively disfavored in some kinds of transaction which would historically have been very ordinary to pay with physical tender, and larger cash amounts were in some situations treated with suspicion, due to its versatility and ease of use in money laundering and financing of terrorism.
