MobilECG, an upcoming open source electrocardiography (ECG) system has recently launched a business card with ECG.
The team's business card crams a one lead ECG, including the digital display and battery, into the smallest package.
This "electroCARDiograph" measures the real ECG signal between the users hands. While it is not a diagnostic device, it is good enough to clearly capture the P, Q, R, S and T waves of the ECG signal.

The technology inside works just like any simple ECG device but is not approved by any regulatory.
