The holy grail remains a tag that can perform authenticated cryptography, sense its environment, and log data—all powered solely by harvested ambient RF, thermal, or kinetic energy. Advances in ferroelectric memory and ultra-low-power RISC-V cores bring this closer.
Research has shifted from simply "tracking boxes" to making tags smarter and more sustainable. RFID Systems- Research Trends and Challenges
However, as global adoption accelerates and new applications emerge—from smart healthcare to autonomous logistics—the limitations of traditional RFID architectures are becoming apparent. Researchers today are grappling with a paradox: while RFID is mature and cost-effective, the demands of next-generation connectivity (high speed, extreme security, energy harvesting, and integration with Artificial Intelligence) are pushing the technology to its limits. The holy grail remains a tag that can
Instead of fighting collisions, future readers will use AI-powered SDRs (Software Defined Radios) to decode overlapping tag signals simultaneously, treating collisions as a MIMO (Multiple Input Multiple Output) advantage rather than an error. However, as global adoption accelerates and new applications
