VNPAY Signer by VNPAY

What is VNPAY Signer?
VNPAY Signer is a browser extension for digital signing, designed for customers using VNPAY services. Whenever you need to sign a transaction on a VNPAY website, this extension securely connects the website to the signing software already installed on your computer.
What you can do:
- Sign transactions securely — Sign online transactions quickly and easily, no complicated steps required
- View your certificates — See all your digital certificates at a glance: which ones are active, expiring soon, or already expired
- Check connection status — A simple status icon shows whether the signing software on your computer is ready to go
- Control access — You're in charge: approve or deny which websites can use your digital
signature
In simple terms:
Think of this extension as a smart bridge. When a VNPAY website needs your signature, the extension will:
1. Check if the website is trustworthy
2. Pass the request to the signing software on your computer
3. Send the signed result back to the website

The whole process happens automatically — you don't need to do a thing. Most importantly: your digital signature and private keys stay safely on your computer and are never sent over the internet.

What you'll need:
To use this extension, the VNPAY Signer software must be installed on your computer. Please contact your system administrator or VNPAY technical support for installation help.
