Signature pad signatures are a blending of electronic signatures and handwritten signatures. You write your signature on a digital pad which captures your handwriting and converts it into an electronic format. This signature is then added to the form, along with a graphic that shows the handwriting. Thus, Signature Pad signatures provide a familiar feel for the signing process.
Most Signature Pad solutions also offer biometric analysis of the signature. This means that the software will examine the signature and compare it to a sample signature that is on file. It will also study specific details of the signature, including how hard the pen is pressed, the angle of the pen against the surface, the writing speed, and so on. If the two signatures match, then the identity of the signer is safely established.
® Forms does not directly support biometric analysis (the comparison of a signature to a stored copy to detect differences between them) of signatures, but the program used by the signature pad may do this comparison.
These signatures use a Signature Pad that plugs into your computer. The signature pad allows the user to create a handwritten signature that is applied to the form. Before you can use these signatures, you must have the following:
- A signature pad
- Software that enables the signature pad.
Signature pads and their supporting software are available from a variety of vendors. IBM
Forms Viewer supports the signature pads from Interlink, Topaz, and any WinTab compliant signature pad company.
Signature pad signatures require you to install both hardware and software on the end user's computer. In addition, there is usually a server-side component that stores the sample signatures and compares all new signatures to the samples.
When to use Signature Pad signatures
Signature Pad signatures are more useful than digital signatures; however, they require a certain level of overhead to create and maintain.
In general, large organizations that require legal signatures from their customers, such as banks, are good candidates for Signature Pad signatures.
