Ren turns any phone into a till for digital dollars. Your customer taps or scans, and the money settles on Tempo in about a second, straight to your own wallet. No card machine, no card fees, no waiting days to get paid.

Ren Terminal, for shops

Your phone is the card machine

  • Pair any phone with a one-time code. Staff phones get a key that can only take payments.
  • Every payment lands live on your dashboard, with the on-chain proof one click away.
  • Money settles to your own address. Ren never holds it, so there’s nothing to withdraw.

Ren Pay, for people

Pay a shop in Singapore with dollars from London

  • Tap to pay at the counter, confirmed with Face ID. Your key never leaves your phone.
  • Send money to anyone, anywhere, in seconds, for a fraction of a cent.
  • See every amount in your own currency: dollars, euros or pounds.

One price, read in everyone’s own money

$12.50 €11.50 £9.88
At Ren’s published reference rates. Payments always settle in dollars (USDC).

Ren Private, on a Tempo Zone

Pay people without the whole chain watching

Keep dollars in a private balance that Tempo’s explorer can’t see, and send them to anyone privately. Move them back to your balance whenever you like.

  • Only you see your private balance, once your passkey says it’s you.
  • Tempo sees dollars going in, not who they’re for.
  • Back in your balance in seconds, for under a cent.

For developers

One POST to charge. A signed webhook when it’s paid.

Take Ren payments on your own site or till software. Create a charge, show its code, and hear about it the moment it settles. Retries are safe with an Idempotency-Key, and every payment is matched on-chain, so there’s nothing to reconcile by hand.

Ren never holds your money

Settles to you, directly

Payments move from your customer’s wallet to yours. There’s no Ren balance in between, and nothing to freeze.

Keys stay on phones

A Ren Pay wallet key lives in the phone’s secure chip behind Face ID. It never touches a server.

Checked on-chain

Every payment carries a memo tying it to its charge, and Ren verifies it on Tempo before anything says Paid.

Your counter is ready when you are

Open a shop in a minute. Pair your phone. Take your first payment before your coffee goes cold.
