How Do I Use LiarCard?
It's quick and easy. Just input your PIN and then the destination number. You'll be up and running in seconds.
Once your call begins, you'll be able to engage in a natural conversation without the need to ask direct questions like "where were you?", remember it's not what is said, but how it's said that matters.
During the call, a heartbeat pulse is played in the background which only you will hear. When the called party is stressed about what is said then you'll hear it beat quicker and then slow down again if they're being truthful. A buzz is played when the called party is suspected of not telling the truth or is in an extreme state of mind.
