Colour LCD Signature Pad Omega
Purpose of using digitized signature is the same as traditional signatures. They are both used to authenticate documents and the only difference is that digital signature authenticates digital document including word, PDF, or email among others. To sign a digital document one would require a digital ID that can be obtained from certification authorities like VeriSign, Adobe and such others. Once obtained, it can be used with compatible programs like the Adobe Acrobat and Microsoft Outlook using the "sign" feature of the program to digitally sign the electronic documents. In brief, the digitized signature is a small data block that is attached to the document and is usually generated from the digital ID of the signer.
