Explanation

A smart card is defined by the embedded silicon chip (an integrated circuit) that stores and processes data securely - this is what makes it "smart," giving it computational ability far beyond passive cards. A picture (A) is an optional visual element found on many ID cards but carries no functional data. A bar code (B) is a feature of magnetic stripe or printed cards, not smart cards - bar codes can't actively process or encrypt information. An expiration date (D) is common to many card types (credit, library, etc.) and is not unique to smart cards.

Memory tip: Think "smart = chip" - just like a smartphone needs a processor chip to be "smart," a smart card needs a silicon chip to store and process data. If it just has a bar code or a picture, it's not doing any thinking.
