The requirement [0] is “Must reject entry to anyone using a fake or duplicate ID.” I gather that the bars have determined that the easiest way to detect duplicate IDs is to outsource to these services that capture IDs and can be queried at time of entry. I have no idea how long they keep them, but it seems safe to assume they would value the data forever.
