Windows 10/11 · TWAIN & WIA

Add document
scanning to
your web app

Q: Can we build before we have a domain?

Yes. Every key we issue covers localhost alongside the production domain you name. Additional live domains, staging included, are arranged with us.

Q: How does the 14-day trial work?

Request a 14-day trial and we issue a key bound to your domain. The trial unlocks every Enterprise feature and shows a visible evaluation banner. No payment is required.

Q: Does the end user have to activate anything?

No. You set license-key once in your page. The service activates that machine silently at the first scan.

Let Windows users scan from TWAIN and WIA devices directly into the record they are working on. Use the ready-made interface or the local API, then receive the PDF or image in your own code.

The workflow

From paper to
the right record.

Your user opens a customer, claim, shipment or case, scans the paper and saves. Your handler receives the Blob and stores it where your application already expects it. ScanBridge provides the missing connection between the browser and the Windows scanner.

Scan inside
the workflow.

Keep the user in the customer, claim, shipment or case they already opened. No scan-to-folder step and no browsing for the file afterwards.

or local API.

Ship the scan dialog as it is, customise it with Enterprise, or call the six local endpoints from your own interface.

Save a PDF, PNG or JPG through the same handler you use today. Professional combines up to 100 scanned pages into one document in the browser.

One tag.
One event.

The web component is a custom element. Drop it in the page, listen for one event, and you have the file. Everything else is optional.

what you write

import '@scanner/web'

<scanner-widget
  license-key="SB-…"   // issued by us, bound to your domain
  file-type="pdf"
  lang="en">
</scanner-widget>

const scanner = document.querySelector('scanner-widget')

scanner.addEventListener('saved', e => {
  upload(e.detail.blob)
})

scanner.addEventListener('closed', onClosed)

scanner.show()

what you get back

// event.detail, for file-type="pdf"
{
  "fileType": "pdf",
  "blob": Blob   // application/pdf
}

// for png or jpg, one entry per page
{
  "fileType": "png",
  "pages": [ {
    id,

  } ]
}

The port finds itselfThe client walks 18625 to 18688, takes the one the service answers on, and remembers it. You never configure it.

The browser pairs onceThe site asks, Windows opens the service, and the browser gets a token for that origin. Every call after that carries it. Only /status answers without one.

The component is optionalIt is one caller. Anything else running in that browser can call the same endpoints.

Rollout

If the service
is not there yet.

Two ways it gets onto the machine, and the widget handles both. Neither of them ends with a support ticket.

scanner-widget

The install dialog the widget shows when the service is missing

path one

The user installs it

The widget notices the service is not answering and offers the installer itself. Download, install, then Verify. No link to send, nothing to explain.

1.5 MB installer2.5 MB on diskno admin rights required

path two

The administrator pushes it

One MSI, pushed to your users the usual way. Those users never see the dialog on the left at all.

the download always resolves to the current build

Security

The scan stays
on the machine.

Nothing is uploaded to make scanning work. What your application does with the file afterwards is your decision, not ours.

The page

Pages arrive as blobs and the PDF is merged here

Wherever you send it

Your handler, your server, your rules

Steps 1 to 3 never leave the machine.
~~Step 4 is your code.~~

The user never types a key

You set the licence key once, in your own bundle. The helper activates it quietly on the first scan.

license-key, set by you

Bound to your domains

The licence carries an allow-list of origins. A key copied out of your bundle does not work on somebody else's host.

origin allow-list

Fail closed

Without a valid verdict the scan flow does not open. There is no client-side switch that lets it through anyway.

no scan without a verdict

Offline, but not forever

An activated machine keeps working without a connection until the licence really expires. A revocation on the server always beats the cached answer.

revocation wins

Limits

Windows only.
Said up front.

The browser is not the limit. The operating system is. Better you find that out here than three meetings into a purchase order.

Operating system

Windows 10 and 11~~x86 and x64. Windows 10 needs .NET Framework 4.8, which every build since the May 2019 update already carries.~~

Browsers

Any modern browser on that machine~~Chrome, Edge and Firefox tested. Nothing in the client is Chromium specific.~~

Drivers

TWAIN or WIA~~A device that exposes neither is invisible to us. We do not talk to hardware directly.~~

Not supported

Internet Explorer, and anything that is not Windows~~macOS, Linux and mobile have no service to talk to. No date we are willing to promise.~~

Built for document workflows

The scanner belongs
inside the application.

ScanBridge fits products where a Windows user already has a record open and the next action is to attach paper to it. The scan returns to your code, so your storage, permissions and workflow stay in charge.

DMS & archives

File to the open record

Capture a document while its folder, case or metadata is already selected.

ERP & CRM

Remove the upload detour

Attach signed forms, invoices and customer documents without scan-to-folder first.

Claims & intake

Keep a packet together

Use Professional to scan, review and save up to 100 pages as one browser-built PDF.

Logistics & back office

Use the scanners already there

Connect the web workflow to TWAIN or WIA devices on existing Windows workstations.

Developer resources

Start with the
question you have.

Pricing

Per application.
Not per seat.

One licence covers one production application, with no charge per internal user or workstation. Every key also covers localhost for development. Yearly pricing includes two months compared with paying monthly. Prices in USD.

Questions

Asked before
every purchase.

These come up before the paperwork starts, every time. If yours is not here, the address is at the bottom of this page.

Can we build before we have a domain?

Yes. Every key we issue covers localhost alongside the production domain you name. Additional live domains, staging included, are arranged with us.

Does it work with our framework?

Yes. The widget is a plain custom element, so anything that renders HTML can mount it: React, Angular, Vue, or a server rendered page. Ready made snippets for each are in the install docs.

How does the 14-day trial work?

Request a key for your domain and we issue it without payment. For 14 days you can use every Enterprise feature, including all eight languages and interface customisation. A visible evaluation banner remains in the widget during the trial.

On how many machines can we install it?

As many as you need. The licence covers one application, not a count of machines or users, so the installer goes on every workstation that has a scanner, for each user who scans there.

Does the installer need administrator rights?

No. A standard user can run it, because it installs for that user rather than for the whole machine. Who runs it is your policy, not our requirement.

Does the end user have to activate anything?

No. You set license-key once in your page. The service activates that machine silently at the first scan.

Does it work over remote desktop?

ScanBridge is not currently certified for RDP, Citrix or multi-user terminal server deployments. The supported setup keeps the browser and helper in the same Windows user session with access to the scanner. Test your exact setup during the trial and talk to us before purchase.

Contact

Try every feature.

Tell us the domain and what you are building. We will issue a 14-day Enterprise trial with every feature unlocked and no payment required.
