Description
aSignatureOffice is the Android app of the xSignatureOffice product family and enables legally compliant signing of PDF/A documents – directly on your Android smartphone or tablet, both online and offline. The app connects to a webSignatureOffice server and can be fully integrated into any web-based solution. It is ideal for mobile use cases where electronic signatures must be captured securely and efficiently – such as in field service, on-site appointments, or digital form processing. aSignatureOffice captures not only the visual representation of the signature, but also biometric data such as timing and stroke dynamics – in the highest possible quality. This ensures compliance with the EU regulation for advanced electronic signatures. No third-party software is required (e.g., no Adobe Acrobat). For developers and system integrators, the app is also available as a component for integration into custom Android applications. Note: A valid user account on a webSignatureOffice server is required to use the app. Learn more: www.webSignatureOffice.com
