Is the code I paste sent to any server?

No. Decoding and image reading happen in your browser. The code, the image and the Pix key are not sent anywhere, and no request is made to the URL of a dynamic QR.

Does this tool pay or generate a Pix?

No. It only reads and checks the code. To pay, use your bank app, and to generate a code, use your PSP's API or SDK.

Why does the CRC show as invalid?

The CRC is calculated over all the text before it. If a character changed after the code was generated, or if the generator calculated the CRC over a different text, it stops matching. The tool shows the expected value so you can compare it with what the generator returned.

Can I paste a code with line breaks?

Yes. Codes copied from a PDF, an e-mail or WhatsApp often arrive split across lines. The tool removes the line breaks and the spaces at the ends before decoding. Spaces in the middle stay, because the merchant name can have them.

How do I tell whether a QR is static or dynamic?

Look at the Pix account template (field 26). If it has the key in sub-field 01, it is static. If it has a URL in sub-field 25, it is dynamic. The page summary already shows it.

Why can't I see the amount of a dynamic QR?

Because the amount, due date and the other data sit in the payload that the receiver's PSP serves at the URL in field 25. The code only carries the address. This page does not open that URL.

Which key types does the tool recognize?

CPF and CNPJ (alphanumeric CNPJ included) with a check digit test, e-mail, phone in the +55 format with area code, and the random key, which is a UUID. The random key in the Central Bank example is a version 1 UUID, so the version is not enforced.

Why did the name or the city get a length error?

The manual limits the merchant name to 25 characters and the city to 15. Some generators cut the text without adjusting the declared length, or count accented letters as more than one character. The error position shows where the limit was passed.

Why is image reading missing in my browser?

It needs the BarcodeDetector API, which exists in Chrome and browsers based on it but not yet in Safari or Firefox. In those, paste the code as text.

What are fields 80 to 99?

They are free-use fields that each payment arrangement defines as it wishes. The tool shows their content and does not treat them as errors.

Pix Copia e Cola Reader and Decoder

Paste a Pix Copia e Cola code, or upload the QR Code image, to see every BR Code field and check the structure and the CRC. Use it to debug a Pix integration or to see what a third-party QR is asking for.

The code is read in your browser only. Nothing is sent to any server, the URL of a dynamic QR is never opened, and the content is gone when you close the page.

How to use the Pix Copia e Cola Reader?

Paste the code

Copy the Pix Copia e Cola from your bank app, a PDF or a chat. Line breaks are fine and are removed automatically.

Or upload the QR Code

In Chrome and browsers based on it, drag the QR Code image here. The text it contains goes into the field.

Read the summary and the fields

See the receiver, key, amount and txid, then open the table to check each field with its ID, length and value.

Fix what the error points to

Each error carries a character position. If the CRC does not match, the tool shows the value it should have.

What is the Pix BR Code?

BR Code is the Central Bank of Brazil's standard for payment QR Codes. It adapts EMV QRCPS-MPM, used by wallets and card terminals worldwide, and Pix Copia e Cola is the same text that sits inside the QR Code, made for copying instead of scanning.

How the code is built

The text is a sequence of TLV fields: a 2-digit ID, a 2-digit length for the value, then the value. Some fields are templates, and their value is another sequence of fields in the same format.

5913Fulano de Tal

59: ID of the merchant name
13: the value has 13 characters
Fulano de Tal: the value

Fields you will find

00: payload format indicator, always 01.
01: initiation method, 11 for a reusable QR and 12 for single use.
26: Pix account. It holds the GUI br.gov.bcb.pix (00), the key (01), an additional note (02) and, in a dynamic QR, the payload URL (25).
52: merchant category code (MCC), 0000 when not set.
53: currency, 986 for the Brazilian real.
54: amount, with a dot and two decimals. It may be absent.
58: country, BR.
59: merchant name, up to 25 characters.
60: merchant city, up to 15 characters.
62: additional data. Sub-field 05 is the txid, and *** means there is none.
63: CRC16, always the last field.

Static and dynamic QR Codes

Static

It carries the Pix key inside the code, in field 26 sub-field 01. The amount is optional. It suits simple, repeated charges, and the receiver only finds out about a payment from the statement or from the txid, when there is one.

Dynamic

It carries a URL (field 26 sub-field 25) in place of the key, pointing to the payload on the receiver's PSP. Amount, due date, interest and the charge identifier live there, and the payer's app queries the URL when it reads the code. That is why a dynamic QR is usually single use (field 01 equal to 12).

This page only reads what is inside the code. For a dynamic QR it shows the URL and does not open it.

How the CRC is calculated

The CRC16 guards the code against typing and copying mistakes. The algorithm is CRC16-CCITT-FALSE: polynomial 0x1021 and initial value 0xFFFF, applied to every character of the code up to and including 6304, so without the 4 characters of the CRC itself. The result is written as 4 uppercase hexadecimal characters.

Because the calculation depends on the order and content of each character, changing one letter of the name or one digit of the amount already changes the expected CRC. It catches accidental changes and is no security measure: someone who edits the code can recalculate the CRC.

For the Central Bank manual example, the CRC of the characters up to 6304 is 1D3D.

What stays in the browser

Decoding is a function that runs on the page itself, and QR reading from an image uses the browser's barcode detection API. The code, the image and the Pix key do not go through our servers or anyone else's, and usage events carry none of them. A real Pix Copia e Cola still holds a person's name and key, so prefer test codes when you share your screen.
