GSM Covert Credit Card
The Two-Way Talking Earpiece is worn inside the ear and is invisible to the eye. It allows user to covertly carry on a conversation using any four band mobile network. Audio signals are transmitted to the earpiece from a GSM device containing a SIM card. A powerful inductive coil ensures that audio can be clearly transmitted to the earpiece 40 cm to 60 cm (16-24 inches) away.
The GSM device is designed to look like a credit card. It is equipped with a powerful 35 dB microphone which crisply picks up audio and allows the user to carry on conversations completely undetected. The microphone clearly picks up whispers even when the GSM device is carried below a user's clothes. The battery allows 3-5 hours of talk time and lasts 8 hours on standby. The perfect solution for all covert communication.
