Traveler's checks can also be replaced if they are lost. It is important to keep the numbers of your checks in a safe place so that you may refer to them in case the checks are lost or stolen. The most popular Traveler's check companies are American Express and Citicorp. The checks require two signatures made at different times in order for them to be valid. The second signature, made at the time of purchase, demonstrates that the check belongs to the person who originally signed the check.
Wire transfers are immediate transfers of funds from one bank to another.
Because banks communicate by telephone or telegram, the funds can often be received the day after a wire transfer is requested. Wire transfers must be made in U.S. currency. Banks may hold wire transfer funds from two days to a week. ISS has a list of the banks that will do wire transfers, their numbers and addresses, and the length of time they will hold funds. Some banks will handle wire transfers for persons who are not customers of the bank.
