Check out this incredible working ECG business card

If you want to make a good first impression, having a fully functioning ECG business card is a pretty good way to do it.

It measures the real pulse of the holder by them simply holding two fingers on it for a few seconds. The ECG business card is obviously not supposed to be used as a diagnostic device, but it’s a cool hack project that gives a close approximation of a real ECG.

Since the company behind it, MobilECG, specializes in open-source hardware, it’s released the schematics for the card and software that drives it so anyone can make their own.

I just realized I need better business cards.
