Electrical lead and financial terminal including the lead.

摘要

An electrical lead has a first set of terminals (14) at one end of the lead and a second set of terminals (15) at the other end of the lead. A connector circuit (11,12) respectively connects the terminals (14) to the terminals (15). This circuit (11,12) is adjustable so as to change the connection paths between the first and second sets of terminals (14,15). The connector circuit (11,12) is surrounded by a security enclosure which comprises flexible sheet means of electrically insulating material carrying an array of lines of electrically security conductors. Monitoring means are connected to the security conductors to detect a change in an electrical characteristic thereof resulting from damage to the security enclosure. The invention can be used in a financial terminal, and provides security against a fraudulent attack on the lead intended to gain access to confidential information, such as a personal identification number, transmitted over the lead.
