Provante — Pix Receipt Screening Right on Your Cell Phone
Received a Pix receipt and wondering: is it genuine? Provante quickly analyzes the image or PDF of the receipt and shows signs of possible tampering — all on your own device, without sending anything to the internet.
Ideal for sellers, freelancers, and small merchants who receive Pix payments all day and want a simple way to suspect "photoshopped" receipts before delivering the product or releasing the service.
HOW IT WORKS
- Select or photograph the receipt (PNG, JPG, or PDF).
- Provante analyzes the file structure, the transaction identifier (E2E), the bank's ISPB, the dates, and the consistency of the fields.
- You receive a suspicion score (Low, Medium, or High) with the detected signs, clearly explained.
TRUE PRIVACY
- 100% offline: the receipt never leaves your phone.
- We do not collect, store, or share any data.
- No registration, no login, no ads, and no trackers.
- Works without an internet connection.
WHAT PROVANTE ANALYZES
- Structural fingerprint of PNG images (traces of editing).
- Format origin (suspicious screenshot or recompression).
- Validation of the Pix E2E code (format, bank, and embedded date).
- ISPB verification with the official list of Pix institutions.
- PDF structure (generator, creation and modification dates, signs of re-editing).
- Consistency between the receipt fields.
SUPPORTED BANKS
Coverage grows with each update. Provante already recognizes the layout of receipts from popular banks such as Nubank, Caixa, Bradesco, Inter, and PicPay, and continues to learn new formats.
IMPORTANT — READ CAREFULLY
Provante is a SCREENING tool. It points out possible signs of manipulation in the image of the receipt, but it does NOT confirm that the payment was received. No app can guarantee, based solely on the image, that a Pix payment has actually been credited to the account. To be sure, always check the amount in your bank's app statement. The Provante result is an indication of suspicion, not a verdict.
WHY TRUST IT?
- 100% on-device processing: your receipts are yours.
- Explainable result: you see which signs led to the score.
- Made following the LGPD (Brazilian General Data Protection Law), with privacy from the start.
FREE
Provante is completely free, with no in-app purchases and no ads.
