Wi-fi crime warning to businesses in Wales

Many firms don`t know they can be abused through wi-fi networks they provide!
In this case the target of internet trickers are hotels or bed-and-breakfast venues. They make a large booking and tell the owner of the venue that they will be frowrding more cash to the venue`s account than is actually requaired. They will then ask the owner to refund the excess to what the total cost of the booking is.
Finally, the owner does not receive the cash but the venue falls for it and sends cash in advance to the criminal!!!!!

Why the tricker was able to abuse wi-fi network of  the company? 
The owner of the venues trusted the client and refunded the excees cash without confirming his payment and after awhile  underestood that he has been cheated by one of the clients and due to the lack of security he could not realise that who is responsible for this crime and  was not  be able sue him.

HOW CAN WE AVOID SUCH THESE PROBLEMS?

It is necessary for firms to secure their wi-fi networks with individual key codes. By this way, each client has his own personal key and, if a criminal activity takes place, they would be aware which client has commited the crime!
