Shielding
Providing electrical isolation for a circuit, component, or wire by enclosing or isolating the circuit, component, or wire with a metal enclosure, plate, or foil that blocks any interfering electrical field.

Short Circuit
An unintentional connection that provides a low resistance path between two points in a circuit or between a point in a circuit and ground. A Short Circuit can drastically affect the operation of a circuit. If excessive current flow results from the Short Circuit, a device may be damaged or ruined.

Signature Verification
A biometric identification method using a person's signature characteristics (writing speed, pen pressure, shape of loops, etc.) to identify that person.

Spike
A voltage peak of high amplitude and short duration. See Transients.

Smart Card
An identification card or access control card with a built-in integrated circuit chip. This gives the card microprocessor memory and intelligence to use for storing data. Also Known As - Chip-In-Card.

Suppression
The addition of a device to an electrical circuit that minimizes or prevents transients from affecting the proper operation of that circuit.

Switch
A device used to either connect or interrupt an electronic circuit.
