Why is cheque not money?

A cheque is not considered money because it is a payment instrument that represents a promise to pay a specific amount from one bank account to another, rather than a medium of exchange itself. While it can facilitate transactions, it requires a bank to process and clear the payment, which can take time. Additionally, a cheque lacks intrinsic value and is not universally accepted as a form of payment like cash or coins. Thus, it functions more as a negotiable instrument than as money itself.
