Amazon can and will charge any card it has on file for you if the card you designate as a payment method falls through.

an Amazon Prime member's unexpected experience.
This policy sure makes me want to review right away which credit cards I have ever used for Amazon purchases and remove any extra ones from my account. Apparently Amazon has added “using any credit card we have on record for you
” language in the Terms and Conditions for the following:
Prime Membership autorenewal (updated Aug. 10, 2016)
Amazon Music (updated Apr. 12, 2016)
Kindle Unlimited (updated Jan. 15, 2016)
Audible (updated June 7, 2016)
Subscribe & Save (no date given)
Amazon Cloud Drive (updated Jan. 18, 2016)
Device purchase monthly payments (no date given)
For now, there doesn't seem to be any way to set certain cards as opted out or “do not charge.” So the only alternative is to remove them, if you want to prevent any unauthorized use.
Fees and Renewal
UNLESS YOU NOTIFY US BEFORE A CHARGE THAT YOU WANT TO CANCEL OR DO NOT WANT TO AUTO RENEW, YOU UNDERSTAND YOUR PRIME MEMBERSHIP WILL AUTOMATICALLY CONTINUE AND YOU AUTHORIZE US (WITHOUT NOTICE TO YOU, UNLESS REQUIRED BY APPLICABLE LAW) TO COLLECT THE THEN-APPLICABLE MEMBERSHIP FEE AND ANY TAXES, USING ANY ELIGIBLE PAYMENT METHOD WE HAVE ON RECORD FOR YOU.
