Answer:
The correct answer is the option 3: traveler's cheques.
Step-by-step explanation:
A traveler's cheque is the name given to refer to a medium of exchange which could be used worldwide by a traveler instead of any hard currency. Its main characteristics are similar to a regular cheque, however this type comes preprinted and with a fixed-amount of money. The traveler's cheque has to be signed by the owner in order to allow them to make an unconditional payment to another person. In addition, the use of this types of cheques has been declined since 1990 when the credit and debit card started to spread more between the travelers and represented an easier way to carry money, therefore that the banks do not provide that service.
