When was your first ever POAP?

AUDM @Macropod_AU retail payment went live in a Sydney café this week. Scan, pay, merchant has bankable AUD almost instantly.
The rail underneath isn't the token. @OpenPasskey settles stablecoin in 1 second on Base, 0% protocol fee, no card network in the path.
Same rail a person taps, an agent pays over x402/MPP. One settlement layer for human and machine money.

AUD stablecoin payments, settling on Base 🇦🇺
What does Australia's first retail payment in AUD stablecoin look like? A Sunday lunch at a Sydney Malaysian takeaway.
Card tap, phone tap, or QR from any wallet. Customer pays @AUDD_digital, merchant keeps it or cashes out to AUD.
No Visa. Settled on @base in seconds.

The QR, explained.
It's a plain ERC-681 URL (Not reinventing the wheel). ethereum:<token>@<chain>/transfer with the amount and a receiving address. Every major wallet already reads this format, so any wallet scans and pays.
Nothing custom to install.
The receiving address is single-use. The terminal derives a fresh one per invoice with CREATE2, so no two payments share
an address and nothing is reused. The customer's wallet sends straight to it, then the funds sweep to the merchant vault.
No new app, no new account, no new card. Just a scan.

The phone tap, explained.
On Android we use Host Card Emulation. The phone presents the same EMV card over NFC, no card needed in hand.
On iPhone the secure NFC path (NFC SE) needs an Apple entitlement. We've applied. Not expecting it soon, Apple moves slowly here.
We've also applied to Apple Pay and Google Pay. Same story, long queue. We're not waiting on either. The QR and card
paths already work on every phone today.

I know celo since 2019 while we were building @AlphaWallet I remember we are also one of the Celo Alliance members. To do local retail payments, we need to work with locally regulated local currency stablecoins which holds local licenses and provide easy minting and redeeming for locals. Different requirements compared to dex trading.

8/8 So: do stablecoin rails win, or does the 10 years acquirer moat hold?
Asking seriously. One of us is right.

1/ Jack’s diagnosis is exactly right. POS is the last payment surface that hasn’t been rethought at infrastructure level. Card rails are still domestic-first with international bolt-ons.
His solution keeps Visa.

Card tap. Phone tap. QR scan. One terminal. Zero middlemen.
Stablecoin payments settling on-chain in seconds, using the same EMV standard every terminal already reads.
Built on @base.

First integration call with a major payment processor.
Their engineers said "adding a new card network requires new development."
Actual work: 3 config entries (AID, CA public key, BIN route) and a URL.
Acquirers hear "new card network" and think Visa-scale onboarding. Your job @OpenPasskey is to prove it's not.
Three ways to pay. No Visa. No banks.
Card tap. Phone tap. QR scan. All settling on-chain in seconds through the same pipeline.
Same EMV standard every terminal already reads. Our own IIN from ISO. P-256 cryptography. Fully decentralized. Non-custodial. No middlemen.

This is not a Visa card. It’s not a Mastercard.
It’s our own card, with our own IIN from ISO, running on the same EMV contactless standard. P-256 cryptography. Settles on-chain in seconds.
No banks. No card networks. No interchange.
Same tap. Different rails.
The RBA just banned surcharges. We removed the fees entirely.
Built on @base
Banning surcharges doesn't cut costs. It just moves them. Merchants will raise base prices to cover card fees. Banks and Visa keep earning the same money. The only difference: now cash users subsidise card users, and merchants take the blame for price increases instead of the networks that charge the fees. The government went after the party with the least voice instead of the ones collecting the rent.

It takes payment via x402 and MPP as well 👊
physical + digital, human + agent
We built a stablecoin POS terminal that settles directly on-chain @base . No payment processor. No server in the critical path.
Two ways to pay:
📱 Scan: ERC-681 QR, any EVM wallet
💳 Tap: EMV contactless HCE today, NFC SE and EMV cards coming (6690 8200 xxxx xxxx), P-256 verified on-chain
Same vault. Same settlement. Whichever arrives first wins. Same-day AUD to merchant bank account.
Launching first in Australia with AUDM from @Macropod_AU , real AUD-backed stablecoins, real merchants, real receipts.

The x402 ecosystem is growing fast. @CoinbaseDev @stripe @base all building the rails. Builders shipping live services. httpay.xyz is one of the first — ~100 pay-per-call APIs for AI agents. What are you building with x402?

We started OpenPasskey because we saw this gap firsthand.
Walked into 100+ cafes in Sydney. Every owner had a drawer of dead loyalty cards and a POS terminal they barely understood. None of them wanted another app. All of them wanted repeat customers.
One NFC tap. No card. No app. Loyalty earned onchain. That's the whole product.
The Nilson Report is projecting 32B+ cards by 2030. We're betting the next card scheme looks nothing like a card.
1/The Nilson Report just projected 32.62 billion payment cards in circulation by 2030.
But buried in the same issue: Ingenico now supports stablecoin checkout at POS. Worldline is building AI agent payment rails. Visa and Apple are provisioning credentials directly to phone wallets.
The card is dying. The card count isn't.
