Beware of fraudster wanting to upgrade your point of sale terminal

A law firm has advised the Law Society that a fraudster entered its premises posing as a representative of a legitimate company with whom the firm has a relationship. This person claimed that the purpose of his visit was to make an upgrade to the firm's point of sale terminal. Clients use the terminal to deposit funds into the firm's trust account. A quick-thinking law firm representative asked for the fraudster's employee identification and then independently contacted the legitimate company. The company advised that it does not make visits to upgrade point of sale terminals and, further, that it did not have an employee with that identification number. At that point, the fraudster fled the premises. It is assumed that the person wanted banking information to steal funds. Lawyers are encouraged to alert staff about this incident and to independently verify anyone who arrives to perform services who isn't known to the firm.
