Ever tried punching a site with your best cards and setups but that shit just wont budge? Or maybe your cards are burned to a crisp - payment processors have flagged and blacklisted your ass. Frustrating as fuck, right?
Well there's a sneaky little backdoor that most of you overlook: in-app purchases. These mobile money makers operate on different payment rails than regular web transactions, opening up a whole new world of possibilities. This guide will show you how to leverage in-app purchases to breathe new life into those "dead" cards and bypass the usual processor cockblocks.
Reminder: this is extremely specific and only works on platforms that have in-app purchases, but once you get it going can be extremely powerful.
Security Imbalance
Lets talk about security imbalance - when a company's web transactions are locked down tight but their in-app purchases are about as secure as a dollar store padlock.
Take ChatGPT for example. Their web payments run through Stripe, which has gotten aggressive as fuck lately with their fraud detection. Stripe Radar has been going absolutely apeshit these past few months blocking legitimate transactions and treating every card like its radioactive. For carders working with cheap garbage cards, getting a payment through is about as likely as finding a unicorn in your backyard.

Or look at Roblox - they use either XSolla or Stripe for web payments. XSolla demands card enrollment and verification charges. But here's where it gets interesting: these same companies also have mobile apps where you can buy the exact same stuff.

See most companies pour resources into securing their main website payments, treating them like their firstborn child. But their in-app purchase security? That shits completely outsourced to Google and Apple's app stores. Once you figure out the quirks of Play Store and App Store payments youve basically got a master key to card anything these companies sell through their apps. It's like finding a secret tunnel that bypasses all their fancy website security.
Now dont get me wrong - app stores aren't exactly wide open. Both Apple and Google have their own security measures that can be a pain in the ass. But when youre banging your head against the wall trying to card some Roblox credits with your $2 resold cards and getting nowhere on the main site, even a slightly easier target through in-app purchases looks like a fucking oasis in the desert.
This security imbalance creates opportunities. While everyone else is ramming their head against brick wall you will be sliding through the side door of in-app purchases.
iPhone vs Android
Not all stores are created equal, and these two fuckers differ largely in terms of security.
Apple App Store
Apple's security is device-focused - they track and flag suspicious patterns on individual phones. Push too many purchases through a single device especially large ones right off the bat, and Apple will cockblock you. Resetting your device can help dodge some flags but its not a magic bullet. The good news? Unless you're being a greedy fuck running $10k+ daily through one phone, you probably wont get permanently blacklisted. Apple can't completely ban devices from making purchases - imagine the shitstorm if legitimate customers buying used iPhones cant purchase on the App Store.

That said if you're moving serious volume and need more devices, hit up the secondhand market. Some crafty fuckers in China even run card ops out of phone repair shops using devices before flipping them. Smart hustle, and extremely profitable. But this is just for the big boys if youre not planning to move volume this is hardly anything you should concern yourself with.
Google Play Store

Google's a whole different animal. They dont give two shits about devices since Android hardware IDs are extremely unreliable - one click with the right tools and boom, fresh device identity. So instead of focusing on the device they implement the security on the account itself.
Their payment security comes in two flavors: 3D Secure verification or mini-charge verification. If you're planning to hit big, enroll cards that have access to transaction history (or Visa Alerts cards although these cards have low amounts of balances) and verify them properly with Google. Once youre "trusted", they'll let you max those fuckers out before the security algorithms wake up and start asking questions. Just dont get cocky - even trusted accounts have limits before Google brings down the hammer.

Personally I stick with Apple's ecosystem. Why? Because that shit just works. The barrier to entry is way lower - grab a fresh iPhone, format that bitch create a new Apple ID, and youre ready to roll on a purchasing spree. As long as your card is live and kicking it'll work without jumping through a million hoops.
No need to verify mini-charges or deal with Googles trust bullshit. No account aging requirements or complex device spoofing needed. Just a clean phone, fresh account and a working card. Simple, effective and reliable as fuck. Sure, you might need to switch devices more often for high volume but that's a small price to pay for consistent success rates.
Subscriptions and Chargebacks
Another powerful force in the in-app carding game is subscriptions. These are fucking gold for both personal use and resale. Why? Because most streaming platforms and subscription services are too lazy to properly implement Apple and Googles chargeback protocols.

See, when a chargeback hits an in-app purchase Apple and Google have systems to notify the merchant. They provide APIs that let companies automatically revoke access when subscriptions get charged back. But companies like HBO, Hulu Disney+ and others? They half-ass this shit. This is especially true if the chargeback is via App Store, since Apple doesn't really provide a convenient way for companies to know which account chargedback only which transaction. Their systems are so poorly integrated that even if you card an annual subscription and it gets charged back a week later, your access often stays active for the full year.
This sloppy implementation is exactly why you see so many "cheap premium accounts" being sold. Those sellers arent magic - they're just carding subscriptions both through the site and via in-app purchases and flipping them quick. Even if the cards get charged back the accounts keep working.
Conclusion
In-app purchases are your secret weapon when traditional carding hits a wall. While everyone else bangs their head against fortified web payment systems, you can slip through app store backdoors like a digital ninja. The game isnt about brute force - it's about finding and exploiting these security imbalances.
Whether youre reviving "dead" cards or dodging processor blacklists in-app purchases open up possibilities that web transactions can't touch. Master this shit and youll have a reliable revenue stream long after others have given up and gone home.
Just remember: greed kills. Keep your volumes reasonable, your devices clean and your OpSec tight. The smart money isn't made in one massive hit - it's built through consistent, sustainable exploitation of these overlooked vulnerabilities.
Now get out there and make that app store money. D0ctrine out.
