+# Cardinal
+Change the images on the cards in your Apple Wallet on iOS 15.0-16.5 (and 16.6b1).
+Tested on an iPhone 13 Pro (iOS 15.3.1, TrollStore & MDC) and an iPhone 12 Pro (iOS 16.6b1, KFD).
+
+## Exploit (per version):
+- iOS 15.0-15.4.1:  TrollStore or MacDirtyCow
+- iOS 15.5-16.1.2:  MacDirtyCow
+- iOS 16.2-16.5:    KFD
+
+## How To Install
+You can use any method you want, such as AltStore, Sideloadly, TrollStore (for iOS 15.4.1 and below only), etc. The ipa file will be in the releases tab.
+
+## Warning for iOS 16.2+
+The kfd exploit likes to corrupt the id after using it multiple times. If this happens, you will have to re-add it. It seemed pretty likely from when I was testing. You might have to delete the app's data after using it once.
+You may also kernel panic after using the app. Your device will be fine, it will only reboot once and then continue working as normal.
+Some offsets may also not be correct for some version and device combos.
+You can ignore this if you are on versions prior to iOS 16.2, as this will not be an issue.
