In answer to the question "How stupid can people be?" we discover the answer. "Really fucking stupid." - They Want Their ID Chips Now (Wired News).

Now let's see. We have a chip that can hold "six lines of text" I assume that's a standard 80-column line - 6 * 80 = 480, which is close enough to 512 bytes to make it a reasonable guess. The chip has no processing capability, and the data on it can't be changed. That makes it about as useful for identification as having a henna tattoo that says "Hi, I'm Charles", and significantly less useful for medical purposes than the Medic Alert bracelet my friend from school used to wear because of his haemophilia.

People. Feh.
