Men who have sex with other men are the primary research participants for this study. Participants’ selection is done by the snowball sampling method. Once selected, a participant is asked to provide references of 3 to 5 other men (recruits). A coupon is provided for this purpose to his recruits. When a recruit comes to the center for testing, the participant earns financial incentives.
After arriving at the test center, participants are asked different questions. After passing the screening test, they take an HIV test and have the option to receive test results.
Hence, it is important to ensure that the data collected is not duplicated. Since there are financial incentives attached, a fingerprint-based identification system was required to ensure that incentives are given to eligible participants only. A proper identification system was necessary to secure participants’ information. As there were multiple test centers, it was necessary that the system was centralized and uniform across all centers.
