Scanning Devices Flashcards
________________ convert scanned text and images into a form that the system unit can process.
Scanning Devices
Five types of scanning devices:
- Optical Scanners
- Card Readers
- Bar Code Readers
- RFID Readers
- Character and Mark Recognition Devices
An ___________, also simply known as a _________, accepts documents consisting of text and /or images and converts them to machine-readable form.
- Optical Scanner
- Scanner
Four types of optical scanners:
- Flatbed
- Document
- Portable
- 3D
_____________ is much like a copy machine. The image to be scanned is placed on a glass surface, and the scanner records the image.
Flatbed scanner
______________ is similar to a flatbed scanner except that it can quickly scan multipage documents. Automatically feeds one page of a document at a time through a scanning surface.
Document scanner
______________ is typically a handheld device that slides across the image, making direct contact.
Portable scanner
____________ use lasers cameras, or robotic arms to record the shape of an object.
3D scanners
_____________ interpret this encoded information. Ex) Credit cars, debit card, access card.
Card readers
The most common card reader is the _______________. Encoded information is stored on a thin magnetic strip located on the back of the card.
magnetic card reader
Many credit cards, known as ____________, include additional security in the for of a microchip embedded in the credit card.
chip cards
_________ or __________ are from grocery stores.
- bar code readers
- scanners
Bar code reader devices are either handheld ___________ or _______________. They contain photoelectric cells that scan or read ________, or the vertical zebra-striped marks printed on product container.
- wand readers
- platform scanners
- bar codes
__________________ are widely used by retail stores to automate the processes to check out customers, to change product prices, and to maintain inventory records.
UPCs (Universal Product Codes)
______________ is widely used y the United Parcel Service (UPS) and others to automate the process of routing packages, tracking in-transit packages, and locating lost packages.
MaxiCode
_______________ are tiny chips that can be embedded in almost everything. These chips contain electronically stored information that can be read using an ____________ located several yards away.
- RFID (radio-frequency identification) tags
- RFID reader
Character and mark recognition devices have three types:
- MICR
- OCR
- OMR
________________________ are used by banks to automatically read those unusual numbers on the bottom of checks and deposit slips.
Magnetic-ink character recognition (MICR)
_____________________ uses special preprinted characters that can be read by a light source and changed into machine-readable code.
Optical-character recognition (OCR)
___________________ senses the presence or absence of a mark, such as a pencil mark.
Optical-mark recognition (OMR)
