This document discusses substitutes for money that were developed through banks to help solve problems with exchanging money in trading activities. It notes that demand drafts, cheques, and ATM/debit cards serve as new methods of substitutes for money. Demand drafts can be cashed through banks and were given in exchange for remitted money. Cheques allow account holders to withdraw money or pay others instead of using physical money, and the recipient can then cash the cheque through the bank. ATM/debit cards serve as the medium for customers to withdraw money from their accounts through automated teller machines at any time.
