Tuhund's e-sign system is a powerful feature designed to bring document authentication and fraud prevention to the forefront of ERP workflows. By embedding a verifiable digital signature into every business-critical document, Tuhund ensures that invoices, bills, quotations and reports remain completely tamper-proof.
At the core of the system is a secure e-signature represented as a QR code, uniquely tied to each document. It acts as the key to verifying authenticity, with all validation handled directly by the Tuhund backend server. Once generated, the signature cannot be modified. Even users with full administrator access cannot alter the signed data. This strict immutability ensures reliable fraud prevention across all levels of access. Verification takes only seconds and is completely automated.
The signature also works in both printed and digital formats. Anyone receiving a document can scan the QR code to check its authenticity, whether they are looking at a PDF or a hard copy. This allows for dual verification and eliminates the need for separate confirmation processes.
In physical or digital form, the e-sign generally contains:
-
A QR code that links to the verification page
-
Signature metadata including server, ID, timestamp, date, user ID and user name.
When the QR code is scanned, the user is directed to the Tuhund Signature Verification Page. This page connects directly to the Tuhund Backend server and displays the actual data recorded at the time of signing. There is no manual entry or uploading involved. The server itself verifies the signature and confirms the identity of the user who signed it, the document details, and the timestamp. A note on the page instructs users to validate the domain name in the address bar, reinforcing secure digital habits.
Unlike conventional PDF digital signatures that rely on specific software or certificate tools, Tuhund’s e-sign can be verified instantly by anyone through a simple mobile QR scan. As long as the link leads to tuhund.com, and the data on the page matches the document in hand, the signature is valid. This makes the system more accessible, transparent and tamper-proof than standard PDF-based approaches.
In conclusion, Tuhund’s e-sign system brings together transparency, traceability and security. It makes forgery impossible, ensures that no document can be modified once signed, and builds trust in every transaction. Whether it is an invoice, a quotation or a delivery note, Tuhund guarantees that the document is genuine, verified and protected.
