you've ever made or received a call using a calling card, you've probably noticed one of the side effects of these
payment systems: instead of your number showing up on the recipient's Caller ID screen, a number owned by the card's
issuer appears. Now a company called SpoofCard has decided to capitalize on this discrepancy by selling calling cards
that are specifically designed to spoof Caller ID
. For about 17 cents a minute, SpoofCard lets you send any numeric string as your Caller ID code. The
service goes even further, providing realtime voice-changing capabilities and call recording. Although SpoofCard's
right to hand over your personal info if they're subpoenaed, we won't be surprised to see this shut down soon. In the
meantime, here's your chance to really confuse those wiretappers.
