Unless you are using an RFID-blocking wallet, I can walk around with a RFID reader and steal your data from your card(s) without you ever knowing. RFID readers are also installed at gas station pumps, and can grab the data from your card. I'm not advocating for Amazon to have my palm print. I'm simply describing why it is better than current RFID credit cards. Palm print is also better than eye scan or fingerprint scan, as fingerprints are not as unique as once thought (i.e., collisions can happen) and fingerprints have been successfully replicated using AI.
