The Accu-Cab consists of a heavy duty, double walled cabinet internally equipped with four RFID Antennae and an electromagnetic door lock. When a user walks up to the Accu-Cab, he or she must identify themselves prior to the door being unlocked. They can do this by using a touch screen monitor mounted on the door or with a bar-code or proximity badge scan. Once the door is unlocked, the user opens the door to find inventory (that is tagged using Passive Gen2 Tags) on adjustable shelving. The user removes the inventory and shuts the door. The inventory is automatically adjusted and the inventory is properly accounted. The same procedure takes place when returning an item. The user identifies who they are to the system and then clicks 'open' to unlock the door. The user places the item back on the shelving in any location. The CribMaster software that drives the Accu-Cab provides all the functionality needed to manage any type of indirect material. From tooling, spare parts inventory, PPE, MRO, etc., CribMaster is a robust and flexible inventory management application that was built by supporting the processes associated with this type of inventory. CribMaster currently has over 1400 customers in 13 countries and is the clear leader in providing technology to assist customers in reducing usage, tracking inventory movement and processes and developing more effective replenishment.
