Biometric registration may improve services associated with HIV research. A cross-sectional, observational survey was used to evaluate biometric fingerprint scanning for identification (ID) verification in the setting of an HIV prevention study. Survey outcomes were dichotomized (discouraged or not discouraged) by biometric scanning and statistical analyses were used to determine if participation decreased by greater than 10% overall and after stratifying by demographic variables and risk behaviors. 206 participants were recruited from a community-based HIV and sexual health research screening program. Participants completed a quantitative survey to assess their perceptions of biometric scanning for ID verification. The majority of participants (n = 160; 77.7%) indicated no deterrence from testing due to biometric scanning, yet a significant number (n = 45; 23.3%, P < .001) reported at least partial deterrence. Research using biometric scanning for ID verification may significantly limit access to HIV prevention services and may risk reducing meaningful participation among marginalized populations.

生物特征登记可以改善与 HIV 研究相关的服务。一项横断面观察调查用于评估生物特征指纹扫描在 HIV 预防研究中的身份验证 (ID) 验证。通过生物特征扫描对调查结果进行二分法（不鼓励或不鼓励），并使用统计分析来确定参与度是否总体下降超过 10%，并在按人口变量和风险行为分层后。206 名参与者是从以社区为基础的 HIV 和性健康研究筛查项目中招募的。参与者完成了一项定量调查，以评估他们对用于身份验证的生物识别扫描的看法。大多数参与者 (n = 160; 77.7%) 表示不会因为生物特征扫描而对测试产生威慑，然而，相当数量（n = 45；23.3%，P < .001）报告至少部分威慑。使用生物识别扫描进行身份验证的研究可能会极大地限制获得艾滋病毒预防服务的机会，并可能降低边缘化人群的有意义参与。
