YRP Ubiquitous Networking Labs Unveils Small Active RFID Tags
Today, YRP Ubiquitous Networking Labs unveiled small Active RFID Tags. They are called "Dice" and the size is about 15mm x 15mm x 15mm. Communication range: about 10m.
- They claim that "Dice" are the smallest active RFID tags in the world
- "Dice" uses the 315MHz frequency band
- If "Dice" communicate every 5 minutes, its battery will last for about 2 years and 3 months.
- "Dice" supports DES encryption
- About 1000 "Dice" tags can be read at once
- "Dice" can be integrated with sensors (for example, an integrated sensor can detect if a baggage is opened
- A pilot test using "Dice" may be done this year (they want to commercialize it soon)
- if manufactured in volume, the price of a "Dice" tag will likely be "lower end of several dollars"
