Companies are increasingly challenged to strengthen the tracking and monitoring of their goods and assets. Whether to ensure the level of quality of fresh fruits and vegetables when it arrives at the grocery store, the effectiveness of a vaccine administered to a patient, maintain the security of a patient or employee, enrich customer care, or examine the movements of a vehicle at a isolated worksite, the ability to gain information on-demand for real- time decision making has been a intimidating task. And, for many industrial sectors, government laws are mandating the capability to follow and monitor the flow of goods in the case of recalls. For many markets, old fashioned RFID solutions have been unable to effectively manage many of these dilemmas. In these applications, RFID has been a technology on the edge, but the trade off between performance and cost restrictions associated with conventional RFID solutions slowed adoption. While passive and active RFID offer some of the essential features and benefits, neither system alone properly resolved these markets’ demands: •Passive RFID Systems: Passive tags are well appropriate for certain applications where retaining details on the tag or reading at long ranges or RF-unfriendly environments is not a challenge. However, while economical, passive systems have very limited range and lack on-board memory to support quite a few real-world applications. As a result, deploying passive RFID solutions usually required redesigns in workflow processes, thus restraining adoption as companies are made to change the way they do business. •Active RFID Systems: While active tag systems provide noticeably better range and performance when compared to passive systems, they come at a very high cost of up to ten times that of passive systems - generally too great to rationalize deployments. Active RFID systems derive from proprietary technologies which prevents wide adoption across a supply chain with different trading associates. Considering the choices of “low price, limited performance” and “high price, high performance”, many businesses either confined their deployments or endured reduced capabilities. •Semi-Passive RFID Systems: A third, new answer is Semi-Passive tag systems. With the launch of the ISO/IEC 18000-6:2010 standard, battery-assisted passive (BAP) tags are redefining RFID technologies. BAP-based Class 3 RFID solutions deliver the range, reliability, and a great deal of the functionality observed on active tags but at a portion of the price, finally making real-world RFID applications cost-effective and justifiable for applications previously not well served - offering the best of both worlds.
