How does the use of money make it easier to exchange things?

A shoe manufacturer, M. Salim has to make a payment to the leather supplier and writes a cheque for a specific amount. This means that the shoe manufacturer instructs his bank to pay this amount to the leather supplier. The leather supplier takes this cheque, and deposits it in his own account in the bank. The money is transferred from one bank account to another bank account in a couple of days. The transaction is complete without any payment of cash.
