Revolutionary Technology

Tap to Phone Payments

Leveraging the latest advancements in NFC (Near Field Communication) and softPOS technology, OnePOS turns any Android smartphone into a fully compliant payment terminal.

Queue Busting: Process payments anywhere on the sales floor during peak periods
Pop-up Ready: Perfect for events and temporary locations without heavy hardware
Integrated Experience: No separate terminal—the associate never re-enters the amount
PCI Compliant: Meets all payment security standards

This effectively eliminates the concept of a fixed checkout counter. Your staff can close sales wherever the customer is.

Payment Accepted

No terminal. No cables. Just tap.

100% Browser-Based

This architectural choice is transformative. A new register can be deployed in the time it takes to log in to a website.

Zero Installation

No .exe files to manage. No driver conflicts. No IT support tickets for "the POS won't start." Just open a browser and log in.

Instant Updates

New features and security patches deploy automatically via our CI/CD pipeline. Every store is always on the latest version, instantly.

            Payment Flow
          

// OnePOS to Adyen Terminal
const payment = await adyen.createPayment({
  amount: cart.total,
  currency: 'SEK',
  reference: transaction.id,
  terminal: 'S1F2-000158211234567'
});

// Terminal shows amount automatically
// No manual entry required

if (payment.status === 'AUTHORISED') {
  await transaction.complete();
  await inventory.deduct(cart.items);
  await receipt.send(customer.email);
}
          

Integrated Payments

Zero "Fat Finger" Errors

OnePOS talks directly to the payment terminal via local network or cloud API. The associate never types the amount into the terminal—eliminating costly errors like typing 100 instead of 10.00.

Swish

Vipps

  // Fetch original transaction

    returnRequest.receiptId
  );

  // Verify item was in original purchase
  const originalItem = original.items.find(
    i => i.sku === returnRequest.sku
  );

  if (!originalItem) {
    throw new Error('Item not in receipt');
  }

  // Check return quantity vs purchased
  const alreadyReturned = await getReturnedQty(
    original.id,
    returnRequest.sku
  );

  if (alreadyReturned + returnRequest.qty
      > originalItem.qty) {
