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.


A barcode is a series of alternating dark and light stripes that are read by an optical scanner. The organization and width of the lines is determined by the bar code protocol selected. There are many different protocols, such as the prevalent Code 39.[3] Sometimes the digits represented by the dark and light bars are also printed to allow people to read the number without an optical reader.

There are several forms of biometric identification employed in access control: fingerprint, hand geometry, iris, Voice Recognition, and facial recognition. Biometric technology has been promoted for its ability to significantly increase the security level of systems. Proponents claim that the technology eliminates such problems as lost, stolen or loaned ID cards and forgotten PINs.[citation needed]
All biometric readers work similarly, by comparing the template stored in memory to the scan obtained during the process of identification. If there is a high enough degree of probability that the template in the memory is compatible with the live scan (the scan belongs to the authorized person), the ID number of that person is sent to a control panel. The control panel then checks the permission level of the user and determines whether access should be allowed. The communication between the reader and the control panel is usually transmitted using the industry standard Wiegand interface. The only exception is the intelligent biometric reader, which does not require any panels and directly controls all door hardware.
Most card readers are highly portable and versatile in their ability to read more than one type of memory card. The most common types of memory cards are Secure Digital (SD), microSD, SDHC, microSDHC, CompactFlash (CF), Memory Stick (MS), MS Duo, Mini SD, and MMC. Before buying a reader, make sure it's compatible with the memory card you are using.
If you've maxed out the memory on your camera, action cam, or smartphone, then there's a good chance you've invested in a memory card. Just one catch -- your laptop might not have a compatible port to speak with your memory card. That's where a card reader comes in. These handy go-between devices transmit data between a memory card and your computer. Let's answer some common questions about memory card readers.
Wiegand card technology is a patented technology using embedded ferromagnetic wires strategically positioned to create a unique pattern that generates the identification number. Like magnetic stripe or barcode technology, this card must be swiped through a reader to be read. Unlike the other technologies, the identification media is embedded in the card and not susceptible to wear. This technology once gained popularity because it is difficult to duplicate, creating a high perception of security. This technology is being replaced by proximity cards, however, because of the limited source of supply, the relatively better tamper resistance of proximity readers, and the convenience of the touch-less functionality in proximity readers.
With your own confidential past life reading you will be able to experience moments in your past which have shaped your life. As we grow and develop we often forget these milestones and it can often be quite beneficial to re-visit them; to frame negative experiences in a new positive light, to face old fears and stare them down or to revisit childhood events which might have seemed daunting at the time and re-examine them afresh from a wise and mature perspective.

Writing out your email has the added benefit of letting you rethink your situation and figure out what is the most important to you. Compiling your thoughts this way is a sort of self-therapy that you receive before you even get into the psychic reading. Another benefit to email psychic readings is that you are able to review the response you receive at any time, without having to miss any information that came in.
