Discuss whether barcodes are more or less secure than magnetic stripe cards
What will be an ideal response?
Both barcodes and magnetic stripe cards store information but cannot perform
computations. They have similar security against an adversary who reads the data on them
and tries to decrypt it. Also, Both barcodes and magnetic strip cards can be easily cloned.
Barcodes can be captured from a distance using a camera while reading a magnetic strip
card requires a device that comes in contact with the card. Barcodes are usually printed
on paper, which is more fragile than a magnetic stripe card, typically made of plastic. On
the other hand, paper barcodes do not have the risk of becoming demagnetized.
