Libelium sensor platform for Internet of Things NFC applications
Libelium announces the launch of the new RFID/NFC module for the Waspmote sensor platform. The new RFID/NFC module completes the active tag technology driven by ZigBee with passive tag identification enabling the creation of complex location based services with just one device. The new radio module extends Waspmote features allowing the sensor data to be used in Location Based Services (LBS), such as asset tracking, supply chain monitoring, intelligent shopping or access management.
By using RFID/NFC along with ZigBee , asset tracking can be more accurate along the whole supply chain process. Product management softwares, like ERPs, will access in real time to information related to remaining stock, storage and transportation conditions like temperature and humidity levels, vibrations, light exposure, etc. Security applications, including access control, can also be covered with this technology as the RFID standard -Mifare- uses a 6 bytes key to ensure maximum privacy and authentication requirements, a major concern in this technology.
The information given by the passive tags (cards, keyrings, stickers, etc) is read by the RFID/NFC interface and then transmitted using the ZigBee radio to an Internet Gateway which will finally upload it to a Cloud server making it accessible everywhere. The identification data can also be sent to the Cloud directly using the Wifi radio which performs secure connections with the web servers (HTTPS).
This RFID/NFC radio expands Waspmote connectivity, which already covers ZigBee, Wifi, Bluetooth and 3G/GPRS. "The new module is available in both 125KHz and 13.56MHz bands to ensure compatibility with previous RFID deployments" says Libelium CTO, David Gascón.
