The Swop chip

Tap
anything.

A chip smaller than a fingernail turns a card, a hoodie, a table or a jar into your storefront. One tap and people pay you, collect a stamp, leave a review or land on your page.

Route every tap

Any chip. Any job. You decide where each tap goes.

Put a chip in anything, then point it at whatever you need: a payment, a reward stamp, a review, your booking calendar, your store or your contact card. Change the route any time in the Swop app. The chip itself never changes.

Before you buy

The practical questions.

Does the person tapping need the Swop app?

No. NFC reading is built into iOS and Android, and your page opens in their browser. The app is only for you, to edit what the card opens.

Which phones can read it?

iPhone 7 and newer read it from the lock screen with no setup. Most Android phones from 2017 on read it the same way.

Can I change where it points after I get it?

Yes, as often as you like. The card never changes: edit your Swop page and the card opens the new version.

How do I pay?

By card through Stripe, or with USDC from any Solana wallet, right on this page. AI agents can pay in USDC on Base over x402.

What about shipping and returns?

Shipping is shown on the product and added in your cart before you pay. For delivery questions or a return, email support@swopme.co with your order reference.

One tap. Your whole business.

Order a card, pair it once, and edit it forever.
