"Verification Required" prompt in App Store on iPhone

free apps also ask for a payment method but no funds will be taken.

You can delete the card details once the first free app is installed. You can trust the App store if your phone is not jailbroken.

for folk moving from Android - most good Apple store apps cost a small amount. In return you get good security and no ads. Just my opinion

edit: as above there may be ways round it but eventually you will want decent apps.

Credit Card not required for App Downloads

You can check what the outstanding bill or App Store purchase is that has an outstanding balance by doing the following:

1. Open the “Settings” app in iOS, then go to ‘iTunes & App Store’ and then select your Apple ID
2. Choose “View Apple ID” to access the Account Settings page
3. In the Account Settings section, go to “Purchase History” and scroll through the list to find any item with an outstanding balance – this is what must be paid before you can change your payment information
4. Update your payment information as detailed below to stop the “Verification Required” error message on the iPhone or iPad
5. In the Account Settings section, tap on “Payment Information”
6. Under ‘Payment Method’, choose “None” – or, alternatively, update the payment method *
7. Tap on “Done” when finished adjusting your settings
8. Exit Settings, and return to the App Store of iOS where you are now able to freely download, install, and update apps without seeing any “Verification Required” message
