Spark is an ordering app for smartphone and works as a companion to the incredibly robust Verge Ignite iPad app.
Ordering can be done without accessories using the built-in camera, as well as from order history and templates. A power user can slap on a scanner sled or power on an inexpensive bluetooth scanner for larger orders.
Spark works with your existing Ignite interface. Deploy Ignite iPad app to sales reps for better marketing, to store owners to help them manage their stores and then - with the same interface - deploy Spark in stores as the primary order building tool.
Because Spark can be "bring your own device" (BYOD), you can deploy this to retailers on their own hardware, getting you out of the hardware renting business. What's more, replace your weekly hardware rental fees with a smaller software support fee; they save money, and you pay for the program ... Win-Win!
