Which statement best describes the data capacity difference between proximity cards and smart cards?

• A. Proximity cards can store more information than smart cards.
• B. Smart cards can store and communicate more information than proximity cards.
• C. Proximity cards cannot be read without contact.
• D. Smart cards are always contact-based.

Answer: (B)

The main idea here is how much information each type can store and how they interact with readers. Proximity cards are simple, passive RFID tags with limited memory, designed for quick, contactless access and mostly used for identification rather than storing large datasets. Smart cards contain a microprocessor and more memory, which lets them store larger amounts of data and perform cryptographic processing on the card itself, enabling more complex communications with readers. Because of this, smart cards can store and exchange more information than proximity cards. Proximity cards are typically read without any physical contact, while smart cards can be either contact-based or contactless, so the statement that smart cards are always contact-based and the proximity cards cannot be read without contact aren’t accurate.
