If you were to test the security of such a solution, any suggestions as to what you'd look for or would be concerned about?
The question you've asked is unanswerable because you haven't
said anything about what you want to protect and against whom.
Are you talking about chip-and-pin credit cards in a store?
Turnstile access to a high-security facility? Contact or
contactless cards? Log in to a workstation? To a laptop?
