describe briefly an application for each of the following methods of input
1.MICR
2. key-to-disk
3.video camera
4.touch screen
5.smart card
1. Magnetic Ink Character Recognition (MICR): MICR technology is commonly used in the banking industry to process checks. Each check is printed with a unique combination of magnetic ink characters along the bottom, which can be read by MICR readers. These readers extract the relevant information from the MICR characters, such as bank account number and check amount, and use it for automated processing and verification purposes.
2. Key-to-Disk: Key-to-Disk refers to the process of manually entering data using a keyboard and storing it directly onto a disk drive. This method is commonly used in data entry applications where volume is relatively low, and immediate storage of the entered data is necessary. For example, an organization might manually enter customer details using a keyboard and store them on a disk to maintain a customer database.
3. Video Camera: Video cameras can be used as an input method in various applications. For example, in video surveillance systems, cameras capture live video footage of a particular area, allowing security personnel to monitor and record activities for security purposes. Video cameras are also used in video conferencing applications, where they capture live video feeds of participants, allowing for real-time communication over long distances.
4. Touch Screen: Touch screens are widely used in interactive devices, such as smartphones, tablets, and ATMs. They allow users to interact directly with the display by touching specific areas or icons. For example, in a smartphone, users can navigate through applications, make selections, and input text by simply touching the screen with their fingers. Touch screens are intuitive and provide a convenient and efficient method of inputting commands or data.
5. Smart Card: Smart cards are used in various applications, including access control systems, payment systems, and identification systems. With a smart card, users can input data or perform actions by inserting or tapping the card on a compatible reader. For example, in public transportation systems, users can use smart cards to make contactless payments, simply by tapping the card on a card reader at the entry point. Smart cards provide a portable and secure method of inputting data or authorizing transactions.
