GSL Solutions Inc’s technologies are founded by the marriage of the minds of an engineer and a pharmacist. Both understood from the very beginning that prescriptions are physical products and needed to be tracked physically. Further, they added the requirement that the technology they developed needed to track automatically, without repetitive scanning. These requirements led them to use RFID in their will call storage (IntelliCab™), controlled substance (IntelliVault™), and stock storage (IntelliStock) systems.
