A company called SpoofCard has decided to capitalize on a calling card issuer's number being displayed on the recipient's Caller ID screen, by selling calling cards that are specifically designed to spoof Caller ID systems. 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. SpoofCard's Privacy Policy specifies that the service shouldn't be used for illegal activities and that the company reserves the right to hand over your personal info if they're subpoenaed.
