Flashlight test at bar - update

The edges are sealed properly now. Used to be a weak point

Yeah so I figured I'd follow up on that flashlight test I did the other night at a bar. Quick context - was out with some people and one of them pulled out a UV light keychain, which got me thinking I should actually give mine a proper once-over rather than just the usual visual glance. So I pulled out my phone's light and hit the edges and the back where the laminate meets the card body.

For anyone who hasn't done this before - the flashlight test is really just about checking for delamination. You're basically looking to see if light bleeds through between the layers, especially around the edges and near the hologram overlay. That's where a lot of budget builds fail because the adhesive between the PVC layers doesn't bond evenly, or they've skimped on the lamination process. If you see bright spots or air pockets when you shine a light through the side, that's a bad sign. Mine held up fine across the whole card - no separation at the seams, no light leaking around the hologram borders where I've seen others start to peel after a few weeks in a wallet.

I'll break down a bit more what I looked at while I had the light on it. The hologram overlay construction on this one is layered in properly - you can tell because the light passes through evenly without creating weird refraction spots that would indicate air gaps between the holo foil and the substrate. Some cheaper IDs just slap a sticker-style overlay on top, and those will show immediate delam under a bright light. The ghost image is also worth checking while you've got light on it - you want a subtle, semi-transparent shift that aligns cleanly with the main photo, not something that looks like a separate cutout pasted on. Mine had good clarity there, the usual slight offset you'd expect from a properly applied secondary exposure.

I also ran the light over the perforation pattern while I was at it. Perf quality ties into delamination too because if the holes are punched cleanly without burrs or ragged edges, it means the card stock was handled right during production. Sloppy perforations can create weak points where delamination starts. The pattern on mine was crisp under the light - uniform spacing, no signs of the holes closing up or warping from bad heat sealing on the lam. UV detail accuracy is another thing - I hit it with the keychain UV over the front and back, and the reactive elements came through clearly without bleeding into the surrounding areas. No weird glow where there shouldn't be, which tells me the UV ink was applied in a separate pass rather than being a rushed afterthought.

As for scanner tests - didn't have a proper scanner on me at the bar, but I've run mine through a few different readers since I've had it, and both the barcode and mag stripe parse without errors. The data encoding matches the printed info consistently, which is the bare minimum for passing any real-world scan. Honestly, if the flashlight test shows good construction integrity, it usually correlates with the rest of the build being solid too - you don't get one without the other on a well-made piece.
