Therefore, if you had a device to withdraw money remotely that required entering your pin, and if the security agent asked you for your pin, would you provide it?
The bank PIN isn't really comparable as government agents can access bank info (in UK at least); the only purpose of the PIN is money withdrawal - surely there is no situation where a border agent would be legally asking for that PIN?
If it's going to bother you why not just use a dumb device and a VPN to access your sensitive data?
What if my laptop had similar capabilities?
