ST5500 Transition RFID Reader

Track inventory location and direction

Whether you are a retailer, distributor or manufacturer, you need to know more than the presence of tagged items to harness the power of inventory visibility; you also need to know which direction items are traveling. While standard RFID readers detect presence only, Zebra’s pre-configured, ST5500 transition RFID reader tracks items on the move, providing presence and enabling direction.

A New Layer of Business Intelligence

Zebra’s ST5500 transition RFID reader tracks direction to give you an additional layer of business intelligence, so you can better manage inventory and prevent lost sales, stockouts, theft, and unplanned downtime on the manufacturing plant floor. Plus, with the data over time, you can identify process gaps and improve inventory workflows. The ST5500 provides you with which way a tag is moving through the portal so you can automatically remove it from stock when it goes from the stock room to the sales floor.

Designed for Challenging Areas

Zebra’s ST5500 transition RFID reader works in virtually any area in your facility—from your main building entry and exit areas, including the receiving and loading docks, to interior transition points such as the warehouse and plant floor in a manufacturing plant, it is designed to meet specific needs in challenging areas, such as backrooms and aisles where metal, fluorescent lights and more can create interference. This product is also at home in aisles and will-call areas that require very tight read ranges.

Ready-to-Use, Easy Deployment

Everything you need is already pre-configured and ready to go. Simply suspend from the ceiling or mount on a wall for fast and easy deployment. There’s no need to add any additional components since this transition reader includes both the reader and antennas into one housing. Take your competitive advantage to the next level and gain a greater level of inventory intelligence with Zebra’s ST5500 transition RFID reader.
