A contactless smart card uses the same radio-based technology as the proximity card, with the exception of the frequency band used: it uses a higher frequency (13.56 MHz instead of 125 kHz), which allows the transfer of more data, and communication with several cards at the same time. A contactless card does not have to touch the reader or even be taken out of a wallet or purse. Most access control systems only read serial numbers of contactless smart cards and do not utilize the available memory. Card memory may be used for storing biometric data (i.e. fingerprint template) of a user. In such case a biometric reader first reads the template on the card and then compares it to the finger (hand, eye, etc.) presented by the user. In this way biometric data of users does not have to be distributed and stored in the memory of controllers or readers, which simplifies the system and reduces memory requirements.
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.

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.
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.

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.  
​But the problem is that not all psychic readers are created equal and it can be very difficult deciphering between the fake mediums and the legitimate ​​ones.  For every ​authentic psychic that wants to use their ​natural gift to provide accurate advice and to help others, there are just as many scammers, con-artists, and charlatans looking to prey on unsuspecting victims.

Live video readings are a great way to easily form a connection with your clairvoyant if you are a more face-to-face kind of person. With this method, you can receive predictions, ask questions, and gain insight the same way you would if you were chatting online or over the phone. The main difference is you both are able to actually see one another.  
External devices that can read a Personal identification number (PIN) or other information may also be connected to a keyboard (usually called "card readers with PIN pad"). This model works by supplying the integrated circuit on the smart card with electricity and communicating via protocols, thereby enabling the user to read and write to a fixed address on the card.

While some psychics utilize Tarot cards to assist them, others rely upon astrology or numerology to help them make predictions and provide guidance. Yet other psychics have a spiritual guide that assists them while others simply have a special sixth sense that allows them to perceive things that others cannot. The method used depends upon the psychic and what he or she needs to do in order to tap into his or her psychic gift.

In the 1-to-many mode a user presents biometric data such as a fingerprint or retina scan and the reader then compares the live scan to all the templates stored in the memory. This method is preferred by most end-users, because it eliminates the need to carry ID cards or use PINs. On the other hand, this method is slower, because the reader may have to perform thousands of comparison operations until it finds the match. An important technical characteristic of a 1-to-many reader is the number of comparisons that can be performed in one second, which is considered the maximum time that users can wait at a door without noticing a delay. Currently most 1-to-many readers are capable of performing 2,000–3,000 matching operations per second.
A common proximity format is 26-bit Wiegand. This format uses a facility code, sometimes also called a site code. The facility code is a unique number common to all of the cards in a particular set. The idea is that an organization will have their own facility code and a set of numbered cards incrementing from 1. Another organization has a different facility code and their card set also increments from 1. Thus different organizations can have card sets with the same card numbers but since the facility codes differ, the cards only work at one organization. This idea worked early in the technology, but as there is no governing body controlling card numbers, different manufacturers can supply cards with identical facility codes and identical card numbers to different organizations. Thus there may be duplicate cards that allow access to multiple facilities in one area. To counteract this problem some manufacturers have created formats beyond 26-bit Wiegand that they control and issue to organizations.

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.

This guarantees that you are contacting a qualified & professional psychic guide for each call.
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.

Many Windows users come across the SD card reader not working error after the Windows 10 update and fail to get access to their important SD card data. It's a very nerve-wracking but also common issue that Windows 10 is stuck on the “SD card not recognized” problem. Don’t be worried. In this Windows 10 guide, we’ll walk you through top 4 ways to tackle this card reader not working issue. 

Biometric templates may be stored in the memory of readers, limiting the number of users by the reader memory size (there are reader models that have been manufactured with a storage capacity of up to 50,000 templates). User templates may also be stored in the memory of the smart card, thereby removing all limits to the number of system users (finger-only identification is not possible with this technology), or a central server PC can act as the template host. For systems where a central server is employed, known as "server-based verification", readers first read the biometric data of the user and then forward it to the main computer for processing. Server-based systems support a large number of users but are dependent on the reliability of the central server, as well as communication lines.

Magnetic stripe technology, usually called mag-stripe, is so named because of the stripe of magnetic oxide tape that is laminated on a card. There are three tracks of data on the magnetic stripe. Typically the data on each of the tracks follows a specific encoding standard, but it is possible to encode any format on any track. A mag-stripe card is cheap compared to other card technologies and is easy to program. The magnetic stripe holds more data than a barcode can in the same space. While a mag-stripe is more difficult to generate than a bar code, the technology for reading and encoding data on a mag-stripe is widespread and easy to acquire. Magnetic stripe technology is also susceptible to misreads, card wear, and data corruption. These cards are also susceptible to some forms of skimming where external devices are placed over the reader to intercept the data read.
