Wallet loses card info after ios update

Smart Phones neither have the intelligence nor has the hostility. Hence we need to look at our device settings and the way we synchronise our smart phones with Mac/PC/iCloud and also how careful are we in sharing our sensitive and valuable informations with friends and family members.

Be careful when sharing the device's sensitive and valuable informations with friends and family members.

Thumb Rules:

1. Don't share Apple IDs
2. Don't Jail Break
3. Don't share sensitive informations pertaining to your device and payment methods

To make purchases from the App Store, iTunes Store, or Apple Books, or buy iCloud storage, you need an Apple ID and a valid payment method.

You can typically use these methods with your Apple ID:

• Apple Pay (where available)
• Most credit and debit cards
• Store credit, from redeeming gift cards or from adding funds to your Apple ID
• Country-specific or region-specific additional methods

If you can't make purchases or update apps, including free apps, you need to update your payment method or add a new one. If you already verified that a payment method is available in your country or region and you're still having trouble, learn more.
