What is swish?

Swish is a mobile payment system in Sweden that allows users to transfer money between bank accounts using their mobile phone. It was introduced in 2012 and has since become a popular alternative to traditional banking methods. Swish is owned by a consortium of Swedish banks, and it is widely accepted by merchants in the country. Transactions are fast, secure, and free of charge for individuals, although some commercial users may be charged a fee. Swish is also used by charities and fundraising organizations to collect donations.
