Works with styluses to accurate capture signatures
While styluses are rarely used with most iOS devices, there are situations where they can provide fine drawing abilities beyond what is normally possible with a finger. In particular, styluses are useful where electronic signatures need to be collected, such as for shipping delivery, medical or photographic release forms among other examples. Ten One Design, who make capacitive touch-screen styluses, have developed the Autograph iOS Library for creating and capturing digital signatures that works with XCode and can be incorporated into enterprise or iOS applications.
Licensing the the Autograph iOS library makes it easy to incorporate the company's iOS code into iPhone, iPod Touch or iPad application, integrating easily with UIView or with a built-in modal view depending on how the application wants to use it. Users can customize color, width and size of the stroke, and the software automatic stroke smoothing for more accurate signatures. The stroke is also velocity sensitive, which allows for biometric verification of known signatures.
Developers can also incorporate messages in the signature field to show users exactly what they are signing for, or to verify the name and date. Users can use a three-finger swipe to undo or red strokes, and the library features an optional hash watermark for each signature for security or tracking purposes.
Ten One Design's Autograph iOS library can be licensed on a single-license for one-time use for $99, or a full site license for unlimited use for $499. Demo versions of the library are available for trial use prior to purchase.
