Who Am I?

I had a meeting at PSBank building this morning. The lobby guard asked me for an ID. I left my new drivers license at my portfolio bag at the office. I realized that my "temporary" wallet (which is a really old wallet of mine) had practically no means of proving my identity. I had no company ID, no government-issued ID or anything that will identity me. If a real important situation arose, I could not really prove who I am since there are no government-sponsored biometrics program that would be able to identify me just through my physical characteristics. Our society is very reliant on old-style ID's (which are actually very easy to fake).
