"Legal tender is a medium of payment recognized by a legal system to be valid for meeting a financial obligation. Each jurisdiction determines what is legal tender, but essentially it is anything which when offered ("tendered") in payment of a debt extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the debt is nevertheless discharged. The creditor is not obligated to give change. Some jurisdictions allow contract law to overrule the status of legal tender, allowing for example merchants to specify that they will not accept cash payments. Coins and banknotes are usually defined as legal tender in many countries, but personal cheques, credit cards, and similar non-cash methods of payment are usually not. Some jurisdictions may include a specific foreign currency as legal tender, at times as its exclusive legal tender or concurrently with its domestic currency. Some jurisdictions may forbid or restrict payment made by other than legal tender.[citation needed]" - (en.wikipedia.org 06.10.2019)
