How to prevent fraud?

Using Western Union service, individual clients have been victims of crime. To avoid crime, we suggest the following:

The service of Western Union is intended to transfer money to friends and family or a person you know and trust
The service of Western Union is not intended to buying-selling transactions, where is the risk of fraud
The control number received when filling the cash card is intended to find information more easier, not knowing the control number in the destination country(outside of Estonia) is not an obstacle to withdrawl the money. Control question used in the system is not a problem to withdrawl money.
Imposters need only the name of the recipient and the sender to create a fake document and withdrawl money under the fake name. The information about withdraling and sending the money, should be known to only to the sender and to the recipient. Do not enclose information to a third person.
Do not make copies of the form or send information to a person, who could withdrawl it under a fake name.
