快速指南与实用说明

Bank boleto and collection slip validation

The tool detects standard Brazilian bank boleto and collection/utilities slips, recalculates field check digits, and validates the general DAC when applicable.

The result shows barcode, formatted line, bank, amount, due factor, and free field to speed up payment integration debugging.

Convert line and barcode formats

When you paste a digitable line, the page builds the equivalent barcode. When you paste a barcode, it builds the corresponding digitable line.

Processing happens in the browser whenever possible. Files and inputs do not need to be uploaded to the site server for the main workflow.

  • Modulo 10 field checks
  • Modulo 11 general DAC
  • JSON diagnostic export

Operational limits

Mathematical validation does not confirm payment, beneficiary identity, fraud status, or bank registration. Use it as a technical aid and confirm sensitive data through official channels.

常见问题

Does it query a bank?

No. It validates structure, digits, and fields locally without a bank lookup.

Does it support utility collection slips?

Yes. 48-digit collection lines and barcodes starting with 8 are handled separately.

Can it show the due date?

Yes for bank boletos with a due factor. When needed, candidate cycles are shown.

Yes. The diagnostic can be copied or downloaded as JSON.
