[amp_mcq option1=”Contact smart card” option2=”Contactless smart card” option3=”Proximity smart card” option4=”Both B and C” correct=”option2″]<\/p>\n

The correct answer is: B. Contactless smart card<\/strong><\/p>\n

A contactless smart card is a smart card that can be read from or written to without physical contact with a reader. It uses an electromagnetic field to transfer data between the card and the reader. Contactless smart cards are often used in public transportation, access control systems, and payment systems.<\/p>\n

A contact smart card is a smart card that must be physically inserted into a reader in order to be read from or written to. Contact smart cards are often used in credit cards, debit cards, and electronic passports.<\/p>\n

A proximity smart card is a type of contactless smart card that can be read from or written to at a short distance from the reader. Proximity smart cards are often used in access control systems and payment systems.<\/p>\n

Here is a table that summarizes the key differences between contactless smart cards, contact smart cards, and proximity smart cards:<\/p>\n

| Feature | Contactless smart card | Contact smart card | Proximity smart card |
\n|—|—|—|—|
\n| Data transfer method | Electromagnetic field | Physical contact | Electromagnetic field |
\n| Reading distance | Up to a few inches | Up to a few centimeters | Up to a few inches |
\n| Applications | Public transportation, access control systems, payment systems | Credit cards, debit cards, electronic passports | Access control systems, payment systems |<\/p>\n","protected":false},"excerpt":{"rendered":"
