Unlike traditional RFID and bar codes, the batteryless Memory Spot allows reading, writing, and appending of megabytes of digital content at an on-air data rate of 10 Mbps. Besides providing physical objects with locally stored digital content, Memory Spot can contain links to Web-based content in the same way as RFID. Enabling applications synthesized from local and remote data components provides both compelling utility and an excellent user experience. In addition, having a significant amount of locally accessible content significantly reduces the possibility of service degradations arising from latencies and inaccessibility of the wireless access network and back-end servers. The article addresses the technology's underpinnings; discusses the innovations in its antenna, modem design, processor, and security engine; and describes some applications.
