With the current proposal implanting is not an option as the electrodes wear out.
In principle and using current RFID technology, implanting a device is possible without significant side-effects. On one side an implantable device has to be powered from "outside", on the other side such a permanent device bears the risk of being "hacked". It's not too difficult to emulate passive devices and more sophisticated active devices require quite an amount of power.
In my opinion, the password pill is a crazy and impractical Idea.
When you have now such things as biometrics and retina scans as more authentic and permanent means of person's identification and authentication why would you need such things as pills to be taken every day as a password.
Who will program such pills and how secure they will be from duplication?
Besides extreme security, the author mentioned several other features that are not so extreme, and I think some will achieve significant market success. For example, the bistable secondary screen which, as he points out, "lends itself well to tablet covers which scream out for a dual purpose such as a secondary display."
For serious amateur photographers, and perhaps even pros, the lens array -- especially the separate lens array that communicates wirelessly with the phone -- is a no-brainer.
And on the audio side, it goes without saying that we can expect better voice & music quality, louder, richer-sounding speakers -- even in the tiny form factor required by a smartphone -- and all the DSP that is required to make that happen.
Not extreme at all -- just the natural evolution of features that might've been "gee whiz" a couple years ago, but which are now within the realm of affordability...and desirability.
Imagine someone wants to hijack your car, which depends on you being near it with your "Password Pill" to work. The hijackers will just take you with them for a bit, till they can defeat it. No thanks. (Sorry, I am originally from southern Africa, where car hijacking is somewhat of a national sport.....)
I figured between 1 and 3 days max, thanks for the posting! I would think that someone would instead suggest implanting the chip/pill so that it would not pass but be "permanent". I wonder what the medical effects of such a procedure would be?
I am very doubtful about the swallowed password pill; how long will it "stay with you" and what do you do to keep that pill "in your system"? Seems like a technology looking for an application being forced.. I would rather see it used for medical monitoring. The high resolution displays, especially those with lasting images when off would be a great way to save battery power and still provide user feedback. If needed, the display could wake and refresh with new information and then go back to off/powered down.
