In the 1-to-1 mode a user must first either present an ID card or enter a PIN. The reader then looks up the template of the corresponding user in the database and compares it with the live scan. The 1-to-1 method is considered more secure and is generally faster as the reader needs to perform only one comparison. Most 1-to-1 biometric readers are "dual-technology" readers: they either have a built-in proximity, smart card or keypad reader, or they have an input for connecting an external card reader.
A card reader is a data input device that reads data from a card-shaped storage medium. The first were punched card readers, which read the paper or cardboard punched cards that were used during the first several decades of the computer industry to store information and programs for computer systems. Modern card readers are electronic devices that can read plastic cards embedded with either a barcode, magnetic strip, computer chip or another storage medium.
The word clairvoyance means “to see clearly.” This does not refer to the sense of sight, but rather to seeing with what some call the “inner eye” or “third eye.” Others may refer to this ability as a “sixth sense.” What’s common to all of these terms and definitions is that they refer to an ability to perceive hidden truths. Clairvoyant psychics have the ability to tap into energies that the average person is not able to perceive. For this reason, many people turn to clairvoyants for guidance in various areas of their lives.
