<i>&quot;A church will upload a database of photos of its members, and they usually use security cameras they already have in place to match the video with existing photos. Churches could use it to track regular attendance or see who’s missing.&quot;</i><p>What church is this?  Our Lady of the Panopticon?<p>Why anyone would want to attend service at an Orwellian institution is beyond me.  For centuries, churches have been able to not only track headcount but missing members (in the sense that an elderly attendee perhaps is unwell) without resorting to such Big Brother nonsense.<p>Disgusting.
