AiRISTA Flow offers three types of RFID tags: passive, active, and semi-passive (also known as battery assisted passive or BAP.) AiRISTA Flow gives customers the option of RFID, Bluetooth Low Energy (BLE), GPS, or IR technology. An active RFID tag uses an internal power source (battery) within the tag to continuously power the tag and its RF communication circuitry, whereas a passive RFID tag has no internal power supply and relies on RF energy transferred from the reader to the tag. AiRISTA Flow recognized the need for creation of a single platform that combines the application of each technology. The result is the ability for organizations to deploy not only a single type of tag within their environment, but rather, any combination of the three types of tags.
This platform has opened up the door to a plateau of new types of applications for facilities and hospitals that might be tracking large and expensive assets with active RFID tags, but smaller, less-expensive, or disposable inventory items with passive or semi-passive tag technologies. RFID, RTLS, and GPS solutions belong to a family of solutions referred to as location-based services (LBS.) Only Real-Time Location Systems can use active RFID tags to locate high-value assets and people on virtual maps as they move in real-time. Active RFID technology is enterprise-grade, not to be confused with passive RFID technology, which works only in proximity to specialized RFID readers and provides ‘point-in-time’ location.
AiRISTA Flow’s passive RFID tags rely entirely on the reader as their power source. These tags may read up to 30 feet away depending on the type of material to which they are attached and have lower production costs. Accordingly, they can be attached to assets and inventories that are less costly or exist in high volume. These tags may be manufactured to be disposable, along with the items on which they are placed. A recent breed of passive tags have incorporated electronic elements to store and save the energy received from the reader in a fashion similar to the workings of rechargeable batteries. Tags may then use the power from this source to transmit data in longer ranges of up to 50 feet. AiRISTA Flow offers passive tags that range in various sizes, materials, and colors suited for different applications and assets.
