Abstract
A tamper-evident label that includes a substrate. On the substrate is deposited more than one adhesive. Each adhesive is sensitive to a different condition. The adhesives are deposited throughout the substrate in user-definable patterns. A release layer is placed on the adhesives for ease of transport and application, but is removed prior to affixation of the tamper-evident label.
