Millions of business cards are handed out daily and, in a sea of business cards, it is extremely easy for some to escape the attention of the people they love. It is important to pay special attention to the design of the business card to ensure that you leave a lasting impression with the person you give it to. It seems that a company called Mobile ECG managed to do this.
The company in question specializes in products related to cardiac rhythm, and to draw attention to their products, they created this business card that comes with a built-in heart rate monitor.
To address many people's concerns: yes, this "electroCARDiograph" (name by ldsnowbored on 9gag) 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, as shown in the video.
In fact, the company has agreed to make the source code public on github, along with the schematic, so those who are interested can create their own business card, their own personalized business card, you can. Everything is presented in detail in the clip above.
