Most card readers also offer write capability, and together with the card, this can function as a pen drive. Memory card readersĪ USB card reader like this one, will typically implement the USB mass storage device class.Ī 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, allowing applications to work without knowledge of the reader details. Readers with this class do not need device drivers when used with PC/SC-compliant operating systems, because the OS supplies it by default. It works with USB devices with the specific device class 0x0B.
The latest PC/SC CCID specifications has defined a new smart card framework. If the card is not using any standard transmission protocol, but uses a custom/proprietary protocol, it has the communication protocol designation T=14.
Communication protocols NameĪsynchronous half-duplex byte-level transmission protocol, defined in ISO/IEC 7816-3Īsynchronous half-duplex block-level transmission protocol, defined in ISO/IEC 7816-3.ĪPDU transmission via contactless interface ISO/IEC 14443. Communication is done via protocols and you can read and write to a fixed address on the card. The card reader supplies the integrated circuit on the smart card with electricity. Some laptops have a flash upgradeable firmware. Some laptops have a built-in smart card reader. There are external devices and internal drive bay card reader devices for PC.
Some keyboards have a built-in card reader. See also: Contact smart card and Contactless smart card.Ī smart card reader is an electronic device that reads smart cards.
