Show answer & explanation
Correct answer: D
Concept
Machine-readable document codes are distinguished by what they encode, how they are sensed, and where they are used. Magnetic Ink Character Recognition (MICR) uses magnetisable ink and standardised character shapes so a reader-sorter can capture a printed code line.
Application
On a cheque, the MICR read band contains coded fields that include the cheque serial number and the bank-branch sort code. Because these characters are pre-printed in MICR ink, writing over them with an ordinary pen does not replace the machine-readable magnetic encoding; an altered or unreadable line can instead be rejected during processing.
Cross-check and contrast
OMR detects filled response marks on forms through optical sensing.
A bar code represents an identifier through one-dimensional lines read optically.
A QR code stores data in a two-dimensional pattern decoded optically.
MICR reads magnetically printed characters, matching the specialised code line described on the cheque.
“Question not attempted” records that no response was selected; it is not a coding technology.
Result
The specialised feature is the MICR Code (Magnetic Ink Character Recognition).
