Paid Participation (10 minutes heart signal measurement)

The University of Toronto Biometrics Security Lab is looking for participants within the age range of 18-45 and with no history of cardiac disease. The participant would be required to sit still for 5 ~ 10 minutes while we collect the signal from the fingertip with a light sensor.
For each session, the compensation is $10 dollar gift card (Tim Hortons or Starbucks). Each person could participate in up to 2 sessions with 2 weeks difference in between ($20 in total).
We have had over 100 participants already, but we are constantly looking for more : > Bring your friends if they are interested. Please email to schedule a meeting.70163288_431633950779506_1374369739215732736_n-1
