Direct Data Entry Devices Overview

What is a magnetic stripe reader used for?

• To read data from magnetic stripe cards.

• To charge customers for purchases.

• To scan barcodes on products.

• To write data to magnetic stripe cards.

List one advantage of using a chip and PIN reader.

• Lower transaction fees for merchants.

• Increased security against fraud.

• Faster transaction processing times.

• Easier to use for customers without a PIN.

What does RFID stand for?

• Radio Frequency Interface

• Remote Frequency Identification

• Radio Frequency Identification

• Radial Frequency Identification

How does Optical Mark Recognition (OMR) work?

• OMR works by scanning documents for user marks, analyzing the image to detect marks, and converting them into data.

• OMR works by printing documents with user marks directly onto the paper.

• OMR uses audio signals to detect user responses on a form.

• OMR requires manual entry of data from paper forms into a computer.

Name a disadvantage of using Optical Character Recognition (OCR).

• High processing speed for all image types.

• Ability to recognize handwritten text perfectly.

• Inaccurate text recognition from poor quality images.

• Low cost of implementation for any project.

What type of data does a bar code reader typically read?

• Only numeric data from credit cards.

• Images and graphics from scanners.

• Text data from word documents.

• Numeric or alphanumeric data encoded in bar codes.

How does a QR scanner differ from a traditional bar code reader?

• Traditional bar code readers can read 2D codes from any angle.

• A QR scanner requires a special app to function, while bar code readers do not.

• A QR scanner reads 2D QR codes from any angle, while a traditional bar code reader reads 1D barcodes requiring specific orientation.

• A QR scanner can only read barcodes in a straight line.

What is one common use of RFID technology?

• Enhancing Wi-Fi signals

• Increasing battery life

• Tracking inventory

• Storing customer data

Describe a situation where a magnetic stripe reader would be advantageous.

• A point of sale (POS) terminal for processing credit card payments.

• A tool for measuring magnetic field strength.

• A scanner for barcodes on grocery items.

• A device for reading QR codes at a checkout.

What is a key benefit of using chip and PIN readers in transactions?

• Lower transaction fees for merchants.

• Faster transaction processing times.

• Easier to use for customers without a PIN.

• Increased security in transactions.
