Covert Tagging - Once a bat is deemed genuine, the item is marked with invisible ink which contains a synthetic DNA sequence/combination specific to PSA/DNA.
The DNA-laced taggant can only be detected in a scientific lab or with a proprietary infrared laser. In fact, by using the laser, the invisible DNA-ink will glow "GREEN." More importantly, the chances of replicating this exact sequence is 1 in 33 trillion!
Overt Tagging - A label bearing an alphanumeric serial number is applied on the item in a discrete location or on the Letter of Authenticity. The choice is yours. Interestingly enough, this label was specifically designed to checkerboard when tampered with and can be completely removed! In addition, the label is non-destructive and does not harm your valuable item.
