Reviewers are very satisfied with RightSignature software from Citrix Systems. A cloud-based signature tool with iOS app, RightSignature will save time in every department of your small, medium of large enterprise. You can even add your company’s own branding. There’s no need to worry about security, either, as all data is encrypted and there’s an option for biometric authentification. All signed documents can be saved and shared or even embedded. Great extras are the one-click document prep tool, handwritten signatures and use over all devices. Premium plans include payment collection options, developer API and KBA.
