BARCODE SCANNER • A barcode reader is an optical scanner that can read printed barcodes, decode the data contained in the barcode and send the data to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating for optical impulses into electrical signals. A barcode scanner, also called a point-of-sale (POS) scanner or a price scanner, is a device used to capture and read information contained in a barcode. The scanner consists of a light source, a lens and a light sensor that translates optical impulses into electrical ones.07-Oct-2020 • WOODGPRaOgVeE2 2 BANK

MAGNETIC INK READER • Magnetic ink character recognition code, known in short as MICR code, is a character recognition technology used mainly by the banking industry to streamline the processing and clearance of cheques and other documents. Magnetic ink character recognition (MICR) is a technology used primarily to identify and process checks. The MICR on a check is the string of characters that appears at the bottom left of the check. It consists of three groups of numbers, including the bank routing number, the account number, and the check number. WOODGROVE 3 3 BPAaNgKe

OPTICAL CHARACTER RECOGNITION • Optical character recognition or optical character reader is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo or from subtitle text superimposed on an image. OCR can be used for a variety of applications, including: Scanning printed documents into versions that can be edited with word processors, like Microsoft Word or Google Docs. Indexing print material for search engines. Automating data entry, extraction and processing. WOODGBRPAOaNVgKEe 4 4

CARD READER • A card reader is a data input device that reads data from a card-shaped storage medium. 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. 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. An access control reader can be a magnetic stripe reader, a bar code reader, a proximity reader, a smart card reader, or a biometric reader. WOODGBRPAOaNVgKEe 5 5
