Capture signatures, for just about anything... Wouldn’t it be nice to be able to validate almost any transaction with an easy signature capture? Commonly used to validate and/or reconcile: - Personal Training and Gym Sessions - Massage and Tutoring Sessions - Service Visits - Deliveries, Surveys and more! Well, we have the solution for you! XignOff facilitates the capture and archival of electronic signatures with the touch of a finger on your iPhone, iPad, and iPod Touch. These signatures and their identity are permanently saved (while your account is in good standing) in our cloud together with metadata specific to each signature: time, date and location. The metadata stamped on the captured signature certifies the time, date and place it was captured (providing that the device’s time and date settings are set accurately and its positioning service is enabled) and, at the same time, ensures that the signature is unique and hasn’t been used anywhere else (e.g. copy/paste). XignOff makes it easy to not only capture and store signatures, but it allows for indexing them in ways that make sense to you, since you directly create your own unique indexing structure. As part of your monthly access fee, XignOff provides a fixed number of XOs that you assign, manage and use in any way that you want. You can add as many Tags as you’d like, assign them to Categories which you may chose to create and allocate XOs to them according to your needs. In other words, you have total control on the way you use this service. Because the signatures are stored in our cloud, an Internet connection is mandatory for XignOff usage (Wi-Fi connections are preferred to ensure speed and maximum reliability).
