banks that issued them. Since traveller's cheques do not earn interest, one of the main incentives financial institutions have to sell traveller's cheques is that they effectively represent an interest-free loan from the purchaser to the seller. The sustained decline in interest rates in most of the developed world since the early-to-mid 1990s has substantially reduced the profitability of traveller's cheques for their issuers. Financial institutions have responded to this development by charging new fees for traveller's cheques, increasing existing fees, or by exiting the business altogether. Usage Purchasing cheques for later use Travellers' cheques are sold by banks and agencies to customers for use at a later time. Upon obtaining custody of a purchased supply of traveller's cheques, the purchaser immediately signs each cheque. The purchaser also receives a receipt and other documentation that should be kept in a safe place other than where they carry the cheques. Traveller's cheques can usually be replaced if lost or stolen, assuming the owner still has the receipt issued with the purchase of the cheques showing the serial numbers allocated. Cashing cheques To cash a traveller's cheque to make a purchase, the purchaser would, in the presence of the payee, date and countersign the cheque in the indicated space. Denomination and change Traveller's cheques are available in several currencies such as US dollars, Canadian dollars, pounds sterling, Japanese yen, Chinese yuan and euros; denominations usually being 20, 50, or 100 (× 100 for yen) of whatever currency, and are usually sold in pads of five or ten cheques, e.g., 5 × €20 for €100. Traveller's cheques do not expire, so unused cheques can be kept by the purchaser to spend at any time in the future. The purchaser of a supply of traveller's cheques effectively gives an interest-free loan to the issuer, which is why it is common for banks to sell them "commission free" to their customers. The commission, where it is charged, is usually 1–2% of the total face value sold. Any change for a purchase transaction would be given in the local currency. Deposit and settlement A payee receiving a traveller's cheque would follow its normal procedures for depositing cheques into its bank account: usually, endorsement by stamp or signature and listing the cheque and its amount on the deposit slip. The bank account will be credited with the amount of the cheque as with any other negotiable item
