Does Guardality work if I keep it in my back pocket?

Pressure hasn’t been an issue for mine.

Mine actually stopped scanning reliably after a couple weeks in my back pocket. Not the card itself, my phone just couldn’t read my transit card through it anymore. Front pocket has been fine since.

Mine lives in my back pocket with my wallet and it’s been working for about a year. No bending issues either. The card’s thin enough that I forget it’s there.

Body heat isn’t really a factor since it’s passive, no electronics to fry or anything. The bigger thing with back pockets is that it only blocks what’s actually next to it. If your wallet has a bunch of cards stacked on one side and the Guardality card is on the other, the cards in between might not get covered as well. I tried mine in my back pocket for a while and it worked, just depends how your wallet is set up. Front pocket is easier to keep it close to the cards you care about.

I keep mine in my back pocket too and the thing I noticed is it’s less about heat or pressure and more about what’s between the card and whatever you’re trying to protect. When I first got mine I just tossed it in loose with my cards and it was kind of hit or miss, but once I actually sandwiched it right against the stack in the wallet it started working way more consistently. Sitting on it hasn’t really done anything to mine, it’s still flat after probably four or five months of daily use. My only real complaint is my wallet got noticeably thicker with it in there, which sounds dumb but it’s true. Still keeping it back there though since it hasn’t caused any actual problems.

Back pocket has worked fine for me, same as the front. I’ve been carrying mine in my wallet back there for a few months and it still does its job. Heat and pressure haven’t been an issue at all.

Back pocket seems like a bad spot for anything card shaped, the sitting pressure alone would bug me. I’d personally keep it in the front if that’s already working for you.

I’d be less worried about heat and more about how you sit. The card itself is passive, so it’s not like body warmth is frying anything. But if it’s jammed between your cards and your butt for hours, it’s going to take pressure. That’s the real issue. I’ve seen thin cards and cards get slightly warped from back pocket carry. Once they bend, they can still work, but the blocking part might not be as consistent depending on how it sits against the reader. If it’s working in your front pocket and you don’t want to deal with any of that, just leave it there. Back pocket isn’t some guaranteed failure, but it’s not the ideal spot either.
