It was found that hardly 2 percent of the people who shop use One Palm. Not worth maintaining and upgrading technologies that are not actively being used.

> Amazon One palm authentication services will be discontinued at retail businesses on June 3, 2026. Amazon One user data, including palm data, will be deleted after this date. For more information, click here.

That’s too bad. It’s the one thing I really enjoyed from shopping Whole Foods, they are taking away. The checkout experience with simply scanning palm to apply discounts, pay and just walk away has been very seamless, especially compared to the super slow Safeway self checkout.

Aw ... it was really nice at Whole Paycheck, I'm going to miss it.

Any guesses as to why? Unlike Google Maps Timeline data being subpoenaed, I can't see what LE could use with this (since they have other ways to determine you were at a store), so that can't(?) be the reason why.

Oh wait- was this available in the EU?

This is actually a much bigger signal than it looks like on the surface. Amazon One wasn’t a gimmick. It was one of the most advanced, real-world deployments of biometric identity + payments + authentication ever rolled out at consumer scale. Palm vein recognition is materially harder to spoof than facial recognition, fingerprints, or PIN/phone-based auth. It tied identity, payment, and presence into a single frictionless interaction. You walk in, you exist, you pay, you leave. No phone. No card. No wallet. No password. No MFA prompt. That’s not a novelty — that’s the direction modern authentication has been trying to go for 20 years. And the fact that Amazon is now pulling this back from retail is not because the tech failed. The tech worked extremely well. It’s because of something deeper: regulatory pressure, privacy perception, and liability at scale. When a system becomes too good at identifying a human being, it stops being a retail convenience and starts becoming a governance problem. Amazon One proved something uncomfortable: A company can know exactly who you are, without you presenting anything, and charge you money without you presenting anything. That is an authentication holy grail from a systems engineering perspective — and a political nightmare from a privacy and regulatory perspective. Whole Foods was the proof-of-concept. Airports, stadiums, corporate buildings, and payment rails were the next logical step. The trajectory was obvious: this was going to replace cards and phones eventually. The fact that it didn’t tells you the non-technical constraints beat the technical ones. This is the same reason you don’t see widespread government-grade biometric payments in the West yet. Not because it’s hard. Because it’s too powerful. What Amazon One quietly demonstrated: • Identity can be passive • Authentication can be invisible • Payments can be presence-based • MFA can be eliminated • Fraud becomes nearly impossible • Account takeover becomes nearly impossible • The human body becomes the credential From a systems design perspective, this is extraordinary. From a legal perspective, this is radioactive. Once a palm scan becomes a payment method, it is no longer “cool retail tech.” It becomes: • Biometric financial identity • Cross-store tracking potential • Irrevocable credential (you can change a password, not your palm veins) • Long-term data custody liability And now you’re not in “retail tech” anymore — you’re in “biometric financial infrastructure,” which is a completely different regulatory universe. That’s what this move signals. Amazon is not saying the tech isn’t valuable. They’re saying: “This is not worth the legal surface area for retail.” That’s very different. Because the places where this does make sense are not grocery stores. It’s: • Airports • High-security buildings • Institutional access control • Financial trading floors • Data centers • Government facilities • Enterprise identity verification In other words: places where identity certainty matters more than convenience. Which is exactly why this is interesting. Amazon One showed that passive biometric authentication for payments and access is already technically solved. What stopped it is social acceptance and legal framing, not engineering. And that means the tech will quietly migrate to places where the tradeoff is acceptable. You don’t want palm auth to buy bananas. You absolutely want palm auth to enter a trading floor, a data center, or a secure facility. That’s the real story here. This is the same pattern we’ve seen before: Facial recognition → pulled from public use → adopted in security and law enforcement End-to-end encryption → controversial for consumers → mandatory for enterprises RFID tracking → scary in retail → standard in logistics and asset tracking Amazon One is following the same path. It’s not dying. It’s being repositioned. And the fact they say they will delete palm data automatically is also telling. That’s a signal that the compliance and liability of holding biometric data for millions of retail users is not something they want on their balance sheet. Because biometric data isn’t like email addresses or passwords. If that leaks, there is no recovery. Ever. This entire story is a case study in: When engineering gets ahead of policy. Technically, this is where authentication is going. Socially and legally, we’re not ready for it at consumer scale. But we are ready for it in controlled environments. And that’s where you’ll see this reappear. Quietly. Without marketing. In places where identity certainty is worth more than convenience optics. The irony is that Amazon One proved something incredibly valuable: The future of authentication is not “what you have” (phone/card) and not “what you know” (password/PIN) It’s what you are. We just learned that society is still uncomfortable with that reality when money is involved in public settings. But in institutional and high-trust environments? This tech is gold. So this isn’t a failure. It’s a migration from retail novelty to serious infrastructure.

It was nice when i was on a walk and wanted a snack but had no wallet on me. But i imagine thats a pretty poor use case.

I'm sad but i'm more psyched that Whole Foods got rid of their paper receipts. Need this everywhere.
