If you are already using paper or polyester labels and would not like to switch over to the costlier tamper evident labels, you may opt for a holographic strip on paper / polyester labels, as show in the sample, below. A hologram has a unique 3 dimensional feature & cannot be copied, scanned or re-printed. It cannot be re-used as it is tamper proof. Additional security features like invisible ink printing can also be incorporated in these labels.
