The new Gimme Key Pro is a purpose-built wireless DEX (Data EXchange) device for wirelessly monitoring vending machine inventory and generating invoices for grocery store deliveries. It is cast from an A838 anodized aluminum unibody frame with combat polymer faces, and the processor is upgraded to an ARM Cortex-M4F, making it up to 46 percent faster at accomplishing tasks and going back into a low power sleep state. The new rugged design with these power management enhancements extends the lifespan over two times the legacy Gimme Key. Software development kit and new coding sandboxes are included to simplify integration into enterprise applications.
