Why each option
A magnetically striped card is a contact-based technology that stores data on a magnetic strip, distinguishing it from wireless proximity cards that rely on radio frequency.
A magnetically striped card (magstripe card) requires physical contact with a reader to swipe and read the data from its magnetic strip, making it a contact-based technology. It does not use wireless radio frequency communication or proximity sensing like the other options, which are characteristic of wireless proximity cards.
A passive device, in the context of proximity cards, is a wireless device that draws power from the reader's electromagnetic field.
A field-powered device is synonymous with a passive device, as it gets its operating power from the reader's electromagnetic field.
A transponder is a general term for a device that transmits a response when it receives a query, often used in wireless proximity technologies.
