Direct Data Entry And Associated Devices
Bayani Gaba-gaba
Tap a card on a reader and the bus lets you on; wave a phone over a square pattern and a website opens; an exam board feeds ten thousand answer sheets through a machine and the results appear in minutes. None of this involves anyone typing. This is direct data entry, where a device captures data automatically with little or no human effort, faster and more accurately than a keyboard ever could.
In this lesson you will meet the direct data entry devices the Cambridge syllabus requires: magnetic stripe readers, chip and PIN readers, RFID readers, optical mark recognition, optical character recognition, barcode readers and QR code scanners. You will learn how each one captures data, where it is used, and how to weigh its advantages and disadvantages so you can pick the right one for a given system.
