Retail checkout, reimagined

Tap. Pay.
Walk out.

A paper-thin NFC sticker turns every price tag into its own checkout. Shoppers tap it with their phone, approve with Apple Pay, and walk out verified. A store goes live in one morning.

The hardware

A checkout the size of a price tag.

TAG — tap to pay
Ø 32 mm · 0.4 mm thin · reads under 4 cm · confirms in under a second
01

Passive. Battery-free.

Every TAG-enabled product carries an NFC chip next to its price label. Invisible until the moment someone decides to buy.

02

Every tap, signed.

An antenna coil and a secure element cryptographically sign each purchase — every item carries a verifiable paid record.

Item-level paid status
03

Engineered to disappear.

Tamper-evident — peel it off and the chip goes dead. One tag, one sale.

The checkout

One bag. One payment.

Buying more than one thing? The first tap starts a bag — every tap after drops into the same one. Add, remove, keep shopping, then pay for everything in a single Apple Pay sheet. No app, no account, no five separate confirmations.

1Tap the first item — a checkout opens, branded to the store.
2Tap more, or remove any — the bag and total update live.
3Pay once — one sheet, one Face ID, every item verified paid. Walk out.
The worst lines in retail are gameday pro shops and museum stores — that's TAG country.

How it works

Three steps. No new infrastructure.

Every product on the floor gets a TAG — a secure NFC tag placed alongside the existing price label. The shopper does the rest.

1
Step 01
Pick it up
Every TAG-enabled item has a small NFC chip embedded next to the price label. Passive, battery-free, invisible to the shopper until they're ready to buy.
2
Step 02
Tap to pay
Hold an iPhone or Android near the tag. Apple Pay or Google Pay opens, Face ID confirms, payment completes — all with the wallet already on their phone.
3
Step 03
Walk out
Grab a bag on the way out — the closed bag is the visible sign of a done deal. Staff can verify any item’s paid status with a tap; the store’s security stays exactly as it is.
For retailers

Runs on the team you already have.

TAG is a software layer that connects NFC payment events to the POS and inventory system you already run — nothing gets ripped out and nothing new needs maintaining.

Tags ship to your door. The subscription is monthly. Cancel a pilot at the end of 60 days, no questions asked.

Be the first to pilot TAG.

We're selecting a handful of New York and Miami locations for our first pilots. If you run one — or know the person who does — we'd love to hear from you. Shoppers welcome too: tell us the store you wish had TAG, and we'll go knock on their door.
