Signder is a web service that allows users to acquire handwritten signatures for forms or applications, saving the signer’s information such as timestamp and IP address. The process involves filling out a form, requesting a signature, and then capturing it using various devices before locking it for security. The service also provides examples and resources for implementing the signing functionality into applications.

2. What is Signder ?

3. Signder, the service
• A web service that allows you to acquire handwritten signatures.
• These signatures can be used by forms or client applications.
• Signder can save the image, date, time and IP address of the signer
if needed.

4. How does Signder work ?

5. Filling out the Form
Step 1
• Your web or Windows application allows
a user to fill out information on a form
and to add a signature.
• This signature is attached with the help
of Signder.

6. Requesting a Signature
Step 2
• When a user wants to sign a document
or a form, they click the « Sign » button.
• Your form will then authenticate and
send a reference number unique to the
specific signature request.

7. What’s Happening Behind the Scenes
Step 3
• Our service returns a unique number (a
token) from the signer to the requesting
system.
• Using this reference number, a
signature pad is activated and
presented to the signer.

8. The Signature
Step 4
• Depending on their device, the signer can
sign using a mouse, finger or a pen.
• The signer can redo the signature as
needed before saving.

9. Locking the Signature
Step 5
• The requesting system receives the
signature and places it in the desired
space.
• Once the document or form is
completed and signed, the requesting
system informs our service that the
request is closed. Therefore, the unique
number (the token) used is processed
and the signature is unique and locked.

10. Security
• For security, the signature service
only saves the signature (if
desired).The source system can
recover the signature at anytime
using the unique number associated
with the specific request.
• Along with the signature and
reference number, our system can
save the signer’s IP address as well
as the date and hour of the signing.

11. What’s included to help you take advantage of our
signature service
• A JS, web-mvc or C# example of running a signature service request
from a website, as well as the creation of a report with the signature.
• Scss and Css folders to stylize the signature pad.
