Developed by IBM the PS\/2 interface was often used for connecting keyboard, mouse or trackball to the computer, during the 1990s. Nowadays USB plugs or adaptors replaced this interface almost unexceptional.<\/p>\n<\/div><\/div><\/div>
The Universal Serial Bus (USB) is an established connector for external devices, transmitting data files serially. There are many different types of USB devices, which can be used for storing data, power supply or just to connect devices. The data transmission rate ranges from 12 Mbit\/s (USB 1.0) to almost 20 Gbit\/s (USB 3.2).<\/p>\n<\/div><\/div><\/div>
Recommended Standard 232, developed in the 1960s is a connector which was used in main frame and text terminal applications. Transmitting data files sequencially this interface is hardly used nowadays without converting it to USB.<\/p>\n<\/div><\/div><\/div>
Radio technology enables the transmission of information by modulated electromagnetic waves. Cables are not necessary for the connection of external devices and the computer. Influences such as high electrical current can interfere with the connection.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>
Bluetooth connections only work over a short distance. Data files are transmitted by Point-to-Point or Point-to-Multipoint (WPAN) short-distance radio technology. Interferences are more unlikely because of the short distance. The main purpose of Bluetooth is to connect devices without a cable.<\/p>\n<\/div><\/div><\/div>
The USB nano dongle is a small receiver which connects external devices (keyboard, mouse) to the computer by radio technology. Almost unlimited mobility of the external devices is granted as only one USB-port is needed. The dongle transmitts data files with 2.4 GHz radio technology.<\/p>\n<\/div><\/div><\/div>
Transmitted information are spread on several frequencies within short intervals. Amongst others this technology is used with Bluetooth and WLAN.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
The SCM PC-Card GmbH is a leading manufacturer for chip card readers and OEM. Over the years, chip sets of SCM developed to a quality feature.<\/p>\n<\/div><\/div><\/div>
PC\/SC is a standard interface for chip card readers. Supported by the common operating systems it is used all over the world. Not supporting memory chip cards is a disadvantage of this interface.<\/p>\n<\/div><\/div><\/div>
CCID is a protocol that enables the connection of a chip card to the computer over a USB chip card reader, without inventing an individual protocol. Therefore chip cards can be used as security tokens.<\/p>\n<\/div><\/div><\/div>
Due to the health insurance card the Card Terminal Application Programming Interface (CT\/API) was an attempt to create a standard interface. It consists of a Dynamic Link Library (DLL) and a standardized interface mostly provided by the manufacturers. Impossible to market globally, this interface only exists in Germany.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>
