For work, we use this little card, called a SecureID Card. It's like a little magic secret code generator that gives me the secret and everchanging codes to get into our network, remotely.
I've had mine for SEVEN YEARS and have never misplaced it, 'til yesterday. I looked for hours, then gave up.
Today, my employer mails me the new replacement for the whole SecureID Card system, unsolicited. I no longer need the card.
