Easy Integration

Multiple Signatures

SignaKit groups together many complex functionalities. However, its integration in your app requires just minutes. With only a class and a protocol, you can import SignaKit to your source code with a minimum ammount of code.

SignaKit can handle multiple handwritten signatures per document. In this way, more than one user can sign the same PDF file. This feature is very useful when a contract or an agreement requires the signatures of multiple parties.

Original Document

Original Signature Verification*

You provide SignaKit with the PDF document to be signed. This original document will not be modified by SignaKit. Instead, the framework returns a new document containing the new signatures.

Add a higher security level to your business with biometric signature verification. SignaKit provides a verification engine to perform one-to-one matching using top-notch pattern recognition algorithms.

* This is an add-on feature provided only upon request.
