Florida polycarbonate edge delamination test
Yeah, I ran into the same thing with a few Fl poly batches lately. The delamination feels like a crapshoot — if the 365nm UV light shows sloppy UV bleeds, you know the whole thing's gonna fall apart fast. I've got one that actually passes scan okay somehow, but the tactile laser engraving is barely there. If the lazy holograms are already peeling after a week, that batch is a pass from me honestly. Not worth the hassle.
I’ve been testing a couple Florida polycarbonate IDs lately, and the edge delamination seems hit or miss. The worst one had obvious lazy holograms and barely held together after a week. On a good copy, I check with a 365nm UV light to see if the UV bleeds are sharp — that really separates the decent batches from the duds. The tactile laser engraving should feel slightly raised too. If it passes scan on a PDF417 scanner without issues, it’s usually solid otherwise. YMMV though.
Florida is one of the states where vendors use polycarbonate card construction most consistently, which makes it a good test case for evaluating poly quality. I ran edge delamination tests on three Florida cards from different vendors to see if they pass a strict scan test.
What the edge delamination test checks
Polycarbonate cards are constructed from multiple fused layers. The bond between layers should be seamless at the card edges — you should not be able to feel any edge separation on a scannable id, see any color or texture difference along the edge, or detect any deformation when gentle pressure is applied to the card face. An edge that shows any of these characteristics suggests the layers were not fully fused during production of the fake driver's license.
Testing method
I examined all four edges of each card under a lighted magnifier, then pressed gently on the card face near each edge while watching for any flex or separation. On genuine polycarbonate cards, there is no visible layer boundary at the edge and the card does not flex differently near the edges than in the center.
Results across three vendors
Vendor A produced a card with completely uniform edges under magnification and no detectable flex difference. This matched what I see on genuine Florida licenses.
Vendor B showed a slight color variation at one edge — not a separation, but a visible boundary between layers where the fusion was slightly incomplete. Under magnification you could see the layer boundary as a thin line about 0.5mm from the edge. Not obvious to the unaided eye but present.
Vendor C had a card where one corner showed a slight upward curl of the outer layer, indicating incomplete fusion at that corner during production of the fake driver's license. This was noticeable when handling the card and would likely be caught in a manual feel check.
Why this matters
Incomplete edge fusion is a manufacturing defect that typically worsens over time as the card is used. A card that shows slight delamination at purchase often shows more significant delamination after a year of daily use. For any novelty id, it is worth checking on delivery rather than discovering six months later.
