| 1. A method for capturing an electronic signature of a user in a java based environment on a personal digital assistant (PDA)
for verifying delivery of a package, comprising:
capturing an instance of the electronic signature by a canvas application;
encoding by the canvas the instance of the electronic signature in a file, wherein the canvas application has exclusive access
to captured electronic signatures on the PDA;
encoding an identification number of a second application loaded on the PDA for the delivery of the package to generate an
encoded identifier;
combining the encoded signature with the encoded identifier to generate a signature/identifier pair;
encoding the signature/identifier pair;
transferring the encoded signature/identifier pair to a remote CRM application; and
responsive to receiving a verification from the remote CRM application, if the signature/identifier pair is verified then
authorizing the delivery of the package, otherwise not authorizing the delivery of the package.
