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. - Create apps to do on demand barcode printing, print.A card reader is a data input device that reads data from a card-shaped storage medium. JSTOR ( October 2010) ( Learn how and when to remove this template message)The ACR122U NFC Reader is a PC-linked contactless smart card reader/writer developed based on the 13. Depending on the type of Smart Tag / Smart Card, 2 pages or 12 pages of information can be stored in these smart epaper tags. 1Each.Through Near Field Communication (NFC), information can be read using a PC/SC compliant NFC reader/writer, reader/writer made by AIOI, or mobile devices, such as NFC-enabled smartphones and tablets.

Some laptop models contain a built-in smart card reader and/or utilize flash upgradeable firmware.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"). External devices and internal drive bay card reader devices exist for personal computers (PC). Some keyboards have a built-in card reader. A business card reader is a device used to scan and electronically save printed business cards.A smart card reader is an electronic device that reads smart cards and can be found in the following form:

Most card readers also offer write capability, and together with the card, this can function as a pen drive.Access control card readers are used in physical security systems to read a credential that allows access through access control points, typically a locked door. This allows applications to work without knowledge of the reader details.A USB card reader like this one, will typically implement the USB mass storage device class.A memory card reader is a device, typically having a USB interface, for accessing the data on a memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC). PKCS#11 is an API designed to be platform-independent, defining a generic interface to cryptographic tokens such as smart cards. Readers with this class do not need device drivers when used with PC/SC-compliant operating systems, because the operating system supplies the driver by default. This framework works with USB devices with the specific device class 0x0B. The latest PC/SC CCID specifications define a new smart card framework.
Sometimes the digits represented by the dark and light bars are also printed to allow people to read the number without an optical reader.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. There are many different protocols, such as the prevalent Code 39. The organization and width of the lines is determined by the bar code protocol selected.
Proponents claim that the technology eliminates such problems as lost, stolen or loaned ID cards and forgotten PINs. Biometric technology has been promoted for its ability to significantly increase the security level of systems. This does not address the ease with which barcode numbers can be generated from a computer using almost any printer.Fingerprint identification, access controlThere are several forms of biometric identification employed in access control: fingerprint, hand geometry, iris, Voice Recognition, and facial recognition. 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. 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.
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. The only exception is the intelligent biometric reader, which does not require any panels and directly controls all door hardware.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). The communication between the reader and the control panel is usually transmitted using the industry standard Wiegand interface. The control panel then checks the permission level of the user and determines whether access should be allowed. 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.
Currently most 1-to-many readers are capable of performing 2,000–3,000 matching operations per second.Magnetic stripe technology, usually called mag-stripe, is so named because of the stripe of magnetic oxide tape that is laminated on a card. 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. On the other hand, this method is slower, because the reader may have to perform thousands of comparison operations until it finds the match.
The magnetic stripe holds more data than a barcode can in the same space. A mag-stripe card is cheap compared to other card technologies and is easy to program. Typically the data on each of the tracks follows a specific encoding standard, but it is possible to encode any format on any track.
This technology once gained popularity because it is difficult to duplicate, creating a high perception of security. Unlike the other technologies, the identification media is embedded in the card and not susceptible to wear. Like magnetic stripe or barcode technology, this card must be swiped through a reader to be read. These cards are also susceptible to some forms of skimming where external devices are placed over the reader to intercept the data read.Wiegand card technology is a patented technology using embedded ferromagnetic wires strategically positioned to create a unique pattern that generates the identification number. Magnetic stripe technology is also susceptible to misreads, card wear, and data corruption.
