If you'd like more evidence of what I'm saying, read Smart Cards, Tokens, Security and Applications or Secure Smart Embedded Devices, Platforms and Applications. Both are graduate textbooks covering smart card design and development.
The term "smart card" is frequently misused in popular nomenclature. As a technical term, it refers specifically to contact or contact-less (like NFC) cards with an embedded chip which are, at minimum, physically tamper resistant. For example, a typical credit card is not a smart card. A SIM card is a smart card (or token).
Tamper resistant does not imply tamper proof, which can also be a source of confusion.
