TC is a CS which exists in order to conduct any transfer would it be a transfer or a purchase. Initially, a TC is a final currency if it is different from which the transfer originated (base currency). The cash can differ from American dollar to euro, British pound and many others that exist all over the world. The benefit of it is that a TC can be automatically transformed if the money of the buyer differ from the seller’s currency. The only thing which is necessary – a code of the money, the client just needs to enter it so the currency could be identified.
For instance, if an American enterprise is buying clothes from Italy the fundamental currency is euro whereas the TC is an American dollar.
