Legal tender
The Federal Act on Currency and Payment Instruments (CPIA) stipulates that the Swiss franc is Switzerland's legal tender (currency). Legal tender comprises banknotes, coins and sight deposits at the Swiss National Bank (SNB). Banknotes can be used for payment without restriction, whereas payments in coins are limited to 100 coins per payment. The SNB issues banknotes, while Swissmint, a unit of the Federal Finance Administration, is responsible for minting coins.
