Batch-sign PDFs — invoices, GeM bids, tenders, GST documents — using your own USB DSC token. Your private key never leaves the hardware token.
Filing a GeM bid, a tender, or a batch of e-invoices usually means signing each PDF one at a time through your DSC software — slow, repetitive, and easy to get wrong under deadline pressure.
The DSC Tool automates this: point it at a folder of PDFs, confirm your signing placement, and it signs the entire batch using your connected USB DSC token — the same token you already use today.
Sign an entire folder of PDFs in one run instead of one at a time.
Control exactly where the signature appears on each document.
A record of what was signed, when, and with which token — for your own audit trail.
Signing happens through your Class 2/3 USB DSC token — the private key never leaves the hardware.
Check that a signed PDF's signature is valid and intact before you submit it.
No command line, no scripts — a guided Windows interface from start to finish.
All cryptographic signing is performed by your physical USB DSC token — the tool only orchestrates which PDFs get signed and where. The private key material never leaves the token, and no document content is uploaded anywhere during signing.

No — this uses your own government-recognised DSC token for legally valid digital signatures, not a third-party e-signature service.
The token requires its PIN to be entered for signing, so a person needs to be present to authorise each signing session — this is a security requirement of the DSC token itself.
