Our two-part carbonless sign-in forms perform two jobs in one step. The white first part contains a "blockout" pattern on all names to protect the confidentiality of those signing in. The yellow second part provides an automatic duplicate record that lets only you see the names that are "blocked out" on the white first part. The right side of the set is glued together as an additional confidentiality measure, protecting against peeking inside. Need visitor badges?
