  • Patent number: 5178415
    Abstract: A fingerprint card holder assembly to be used with fingerprint cards having a layer of transparent adhesive material on their front surface where a person's individual fingerprints are received and recorded. The fingerprint card holder assembly has a base mounted on a support platform. A fingerprint card guide is mounted on the top surface of the base for aligning the fingerprint card. A fingerprint card locking unit is pivotally mounted on the base and it pivots from an upright position to a horizontal position that locks a fingerprint card against the top surface of the base. There is structure on the bottom surface of the fingerprint card guide and also on the rear surface of the fingerprint card locking unit to prevent the adhesive on the top surface of the fingerprint card from sticking to either of these respective members when the fingerprint card holder assembly is being used.

  • Patent number: 5013071
    Abstract: The improved fingerprinting system utilizes a conventional fingerprint card having a fingerprint portion on its top surface. A multi-layered sheet having dimensions approximating that of the fingerprint portion has a layer of adhesive material sandwiched between a front liner sheet and a rear liner sheet. The rear liner sheet is removed thereby allowing the layer of adhesive material to be pressed into contact with the fingerprint portion of the fingerprint card. The front liner sheet is transversely scored to form a plurality of strips. One strip at a time is removed to allow fingerprint impressions to be pressed into the respective frames of the particular row of the fingerprint portion. After all of the rows have received their fingerprint impressions, a transparent sheet of plastic material is applied to the top surface of the layer of adhesive material.
