Answer
iAM Smart is the HKSAR Government's digital identity platform, tied to your Hong Kong Identity Card. When a sender requires identity verification, you can use iAM Smart to confirm your identity. If this is your first time using iAM Smart with Foxit eSign, you will need to complete a one-time registration with the Tradelink Document Management and Signing Service (DMSS).
What You Need- A Hong Kong Identity Card (HKID)
- The iAM Smart app installed on your smartphone (App Store or Google Play)
- An active, registered iAM Smart account
- The signing link from the envelope invitation email
Don't have iAM Smart yet? You can register for iAM Smart at iam.gov.hk or search "iAM Smart+" in the App Store / Google Play. Registration requires your HKID and takes a few minutes. Return here once your account is active.
Part 1: First-Time Registration with Tradelink DMSS
The first time you sign a Foxit eSign document using iAM Smart, you will be redirected to the Tradelink DMSS to link your iAM Smart identity. This is a one-time process — subsequent signings skip directly to the signing step.
1. Open the signing link and select iAM Smart
Click the signing link in your envelope invitation email. On the identity picker, click "Continue with iAM Smart →". You will be redirected to the Tradelink DMSS page.
2. Click "Continue with iAM Smart" on the Tradelink page
The Tradelink DMSS page will show: "To sign a document with iAM Smart, you need to login to Tradelink Document Management & Signing Service (DMSS) using your iAM Smart account." Click Continue with iAM Smart.
3. Scan the QR code with the iAM Smart app
A QR code will appear on screen. Open the iAM Smart app on your phone, tap the Scan button at the bottom of the app, and scan the QR code displayed on the Tradelink page.
4. Confirm the login in the iAM Smart app
The app will show a confirmation: "Successfully logged in to Tradelink Document Management & Signing Service (DMSS)." Tap Back on the app, then click Continue on the Tradelink page in your browser.
5. Review the registration request
A welcome page will appear: "Welcome to register Tradelink Document Management and Signing Service (DMSS) through iAM Smart." The system requests your English Name and Email Address from your iAM Smart profile. Click Continue with iAM Smart.
6. Authorise profile sharing in the iAM Smart app
The iAM Smart app will show a "Provide profile information" prompt listing your English name and email address. Tap "Agree to use" to share this data with Tradelink DMSS.
7. Complete the registration form
Your name and email will be pre-filled on the Tradelink Registration page — the data is sourced directly from your iAM Smart account. Check the box to agree to the Terms and Conditions, then click Register.
8. Registration complete
A confirmation page will appear: "Your registration is completed. You can continue your signing with iAM Smart." Click Continue to proceed to signing.
Registration is instant — there is no approval wait time. Once registered, you can sign immediately in the same session.
Part 2: Signing Your Document
After registration (or on subsequent visits when you are already registered), the signing screen will appear:
1. Review the document details
The Tradelink DMSS page will show the Service Name, Document Name, and a unique Identification Code. Note the identification code — you will need to verify it in the app.
2. Open the iAM Smart app on your phone
Switch to the iAM Smart app. A signing notification will appear showing the document awaiting your signature and a countdown timer. Tap "To Sign".
3. Verify the identification code
Confirm that the Identification Code shown in the iAM Smart app matches the one displayed on the Tradelink signing page in your browser. This step protects against unauthorised signing requests.
4. Confirm signing
Tap "To Sign" (or "Confirm Signing") in the iAM Smart app. The app will confirm: "Document successfully signed." Return to Foxit eSign in your browser to complete the envelope.
If your envelope contains multiple documents, you will need to tap "Confirm Signing" for each document individually. The Document Name and Identification Code on the signing page will update automatically after each successful signing.
Frequently Asked Questions
Q: Do I need to register with Tradelink DMSS every time I sign?
No — registration is a one-time process. Once registered, you will go directly to the signing step on future envelopes.
Q: Can I use any iAM Smart account, or does it need to match my HKID?
iAM Smart is one account per person and is bound to your HKID. The identity you register with is the identity tied to your signatures.
Q: What if the QR code expires before I can scan it?
QR codes expire after a short period. If it has expired, refresh the page or click Retry to generate a new one.
Q: What if my iAM Smart app does not show a signing notification?
Ensure your iAM Smart app is up to date and your phone has an active internet connection. Force-close the app, reopen it, and check the notification again. The signing request has a countdown timer — if it expires, return to the browser and restart the signing flow.
Q: Is my signature legally binding?
Yes. Signatures verified with iAM Smart comply with Hong Kong's Electronic Transactions Ordinance (ETO) and use HKSAR Government-grade digital identity recognised by the SFC and other regulatory bodies.
Q: What if I don't have an HKID? Can I still use iAM Smart?
No — iAM Smart requires a Hong Kong Identity Card. If you do not hold an HKID, please use iD-One instead. See the "How to Apply for an iD-One Account" guide.
