I’ve seen the commercials for them around the ‘Net and on television. For example:
If you’ve read much about privacy issues, either in fiction or what’s going on in the world (might I suggest Cory Doctorow’s Little Brother?), you might be as suspicious of these as I am.
Where I’m from (Maine), typically if you get stopped or get in an accident, you’re required to give the law enforcement officer (L.E.O.) your driver’s identification, insurance card, and vehicle registration. Therefore, if your insurance card is digital on your mobile device, you’d need to give the L.E.O. your mobile device (presumably unlocked, unless Apple’s Passport or similar on Andriod works with your device passcode-locked).
Then the L.E.O. takes all of this away from you, back to their car to run checks through their computer.
Suppose your device is passcode-unlocked when you give the L.E.O. your device. What’s to stop them from taking a peek at your pictures for something incriminating? Or at your social media apps? E-mail?
Humans are curious by nature, and given the xenophobia and religious phobias, it wouldn’t surprise me–though it does anger me that this would happen–that an Other (i.e. someone who is not like you, either in race or sexual orientation) would be subjected to such an invasion of privacy.
So, be careful with your devices. Yes, digitizing things are more convenient because most everyone knows where there phone is, but can barely remember where that piece of paper containing their car insurance is right now. At the same time, don’t forget that you are responsible for your own privacy.
Privacy is not always convenient, but it is our right, as given to us in the Bill of Rights.
