barcoder

Turn any payment request into a code you can scan.

Paste the school notice, upload the bill, or check the QR on an invoice. Barcoder reads it, you confirm every detail, and your banking app scans the PayNow code. Nothing is ever paid for you.

3 cases without an account. Then 10 a month, free.

How Barcoder turns a payment request into a code

  1. Any payment request
  2. Barcoder reads it
  3. A PayNow QR any bank app scans

A school notice, a condo management email, a message from your landlord. Barcoder finds the payee, PayNow ID, amount and bill number.

Reading a message uses one case.

The message is read and then dropped: Barcoder keeps the details it found as text, never the message.

Trial cases on this device, no account needed.

Each case’s report, payee details included, is kept as text for 90 days, then deleted. Documents and images are never stored.

Three kinds of payment request, one code at the end.

  1. 01

    Paste a message

    The one parents use most.

    Paste a message
    You give
    A school-trip email, a club fee on WhatsApp, a text from the landlord.
    You get
    A code with every payment detail the message holds. You fill in the rest, or leave the amount to type in your banking app.

    Upload a bill without a code

    No more typing a UEN into your phone.

    Upload a bill
    You give
    A bill or invoice as a PDF, scan or photo, with no QR or barcode on it.
    You get
    The code the bill should have had: a PayNow QR that every Singapore banking app scans.
  3. 03

    Check a code against its invoice

    A swapped QR pays someone the invoice never mentions.

    Check a code
    You give
    An invoice with a QR or barcode you're about to pay from.
    You get
    Whether the code pays who the invoice names, and the amount it states, before any money moves.

AI reads. You confirm.

Reading a message or a document is one case, however many calls it takes. Making a code from details you confirmed, decoding a clean code and looking up a standard stay free.

  1. Read

    Finds the payee, PayNow ID, amount and bill number in whatever asked you to pay.

    Emails and chat messages pasted in; bills and invoices as PDFs, scans or photos; every code already on the page.

    1 case
  2. Confirm

    Shows each value it found and asks you to check the ones it's unsure of, and for what's missing.

    Nothing is filled in that the source doesn't say. Text that tries to instruct the reader is flagged before you go on.

    In the case
  3. Generate

    Writes the code your banking app scans, from the details you confirmed.

    A PayNow QR for the payee’s UEN, with the bill number. A detail the source doesn’t give stays empty: we never guess it.

    Free
  4. Check

    Compares a code already on an invoice with the invoice itself.

    PayNow ID format, EMVCo CRC, payee and amount consistency.

    In the case

Built for the agent that pays the bill.
