1. Are ECG pattern unique for a person? I believe if they are then they are not as unique as fingerprint.
2. I believe the ECG will change dramatically if a person have a panic attack or abrupt mood changes(ex. under severe stress) or any heart condition development. How do you control that ECG pattern and normalize it?
3. How it will be better than just finger print based authentication? I mean if you can develop a good biometrics based on fingerprint that should be enough. Right?
4. Of course it will have a potential to be used in medical devices where a patient using medical device can use that to lock access to others for the data privacy reason.
5. I will be interested to use it but the price range should be around $50-$60 range (However, it is my personal opinion).
Good luck guys.
