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.
​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.
Some people worry that a psychic reading performed on the phone will not be as thorough or accurate as a face-to-face reading. Thankfully, these fears are completely unfounded. Phone psychic readings are every bit as good as an in-person reading, as each advisor is rated anonymously following each call. This guarantees that you are contacting a qualified & professional psychic guide for each call.

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.  
In the 26-bit Wiegand format, bit 1 is an even parity bit. Bits 2–9 are a facility code. Bits 10–25 are the card number. Bit 26 is an odd parity bit. 1/8/16/1. Other formats have a similar structure of a leading facility code followed by the card number and including parity bits for error checking, such as the 1/12/12/1 format used by some American access control companies.

The advantage of using barcode technology is that it is cheap and easy to generate the credential and it can easily be applied to cards or other items. However the same affordability and simplicity makes the technology susceptible to fraud, because fake barcodes can also be created cheaply and easily, for example by photocopying real ones. One attempt to reduce fraud is to print the barcode using carbon-based ink, and then cover the bar code with a dark red overlay. The barcode can then be read with an optical reader tuned to the infrared spectrum, but can not easily be copied by a copy machine. This does not address the ease with which barcode numbers can be generated from a computer using almost any printer.
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.
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.

An important feature for memory card readers is the speed with which they can transmit data. Readers with USB 3.0 compatibility will be faster than USB 2.0 technology (as long as your computer has a USB 3.0 port). As mentioned earlier, there are various types of memory cards, so having a reader than can communicate with more than one interface will be beneficial, especially if you find yourself using multiple memory cards.
