Swish is a mobile payment system in Sweden. The service was launched in 2012 by six large Swedish banks, in cooperation with Bankgirot and the Central Bank of Sweden. It had 6.5 million users as of September 2018. Swish is a member of the European Mobile Payment Systems Association. The service works through a smartphone application, through which the user's phone number is connected to their bank account, and which makes it possible to transfer money in real time, a few seconds until confirmation is received by both parties. The user must have a second mobile application called Mobilt BankID Säkerhetsapp, which is an electronic identification issued by several banks in Sweden. This requires that the user has a bank account in a Swedish bank participating in the system, and also a national ID number. Users who have a Swedish bank account but no suitable phone can register for reception of payments. The phone number can be of another country. The actual transfer is done by the Bankgirot clearing system, which developed instant payments for the Swish system. Swish was originally intended for transactions between individuals, but soon it started to be used for flea markets and collections at church services, and by sports clubs and other organisations as payment at small events where a credit card reader would be too expensive or otherwise impractical. Small companies who wished to avoid credit card charges and simplify online payments soon followed suit. In 2014 organisations could register for receiving payments, although some organisations used a private bank account of someone in the organisation before that. In January 2017 Swish was launched for web based sales which quickly became popular, for example used by the train operatorSJ. It is possible to pay by scanning a QR code. Prior to the implementation of Swish, cash was the primary means for many of these types of real-time transactions. As such, Swish is used for transactions that used to be mostly cash-based. The service is free for private users since the start 2012. Companies and registered organisations pay around 1-3 SEK per received payment in addition to a small yearly fee, and are not allowed to charge the customer for their Swish fee. The fees are decided by each bank for the reason of not limiting price competition, considering that Swish has a near monopoly on instant phone payments in Sweden. Since the minimum Swish payment may be lower than the fee, an organisation may lose money if many small Swish payments are made to it. In some cases of media attention towards such cases banks have donated their Swish profit to the organisations.
