You don't have to carry around credit cards or cash. Instead you can "pay with your palm."
You can link your biometric data (e.g., palm print) to your payment information (e.g., your credit/debit card). It increases user privacy and security in that you don't have to walk around with vulnerable "tap to pay" cards in your pockets.
- endgame 3y agoWhat increases my privacy more is paying with cash.
- drivers99 3y agoI use the pay with palm thing at Whole Foods (owned by Amazon) every day. That also puts in your Prime membership which discounts some things. But that's completely the opposite of privacy. I use the self check-outs which are really fast and efficient there. They don't don't take cash at those though; they have them taped over! When I was on a cash/privacy kick a while back, I noticed paying the self-checkouts with cash (like at Target) was even faster than using a card.
- brevitea 3y ago> "But that's completely the opposite of privacy." Agreed. Privacy is my RFID credit cards not being scanned. Amazon would then hold my user data and sell it to whoever... Which they would also do via my credit card.
- hobobaggins 3y ago"increases user privacy and security" You really think that? Tap to pay cards are easily replaced (revoked) and at no cost to me at all. The only way to revoke my palm is too awful to contemplate!
- brevitea 3y agoUnless 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.

- boppo1 3y agoI struggle to understand how someone with enough tech awareness to be on HN doesn't feel appalled by palm scanners.
- culopatin 3y agoSame
- culopatin 3y agoYou lost me at “increases privacy”. You don’t carry your phone with you?
