Anywhere you go in Tokyo, Seoul or Singapore, the proliferation of personal technology is hard to miss.

And now convicts in these countries won't feel left out. NEC has signed a letter of intent to resell RFID identification and tracking system for prisons from Alanco in Asia. The agreement is non-exclusive in Japan but exclusive in other, unidentified, Asian markets. A definitive agreement, worth several million, will be signed in the next thirty days, said Alanco.

With the Alanco system, prisoners, or "uncooperative users" in Alanco parlance, wear RFID bracelets surrounded by a multitude of readers. As a result, their movements can be tracked. In U.S. prisons where it's been installed, Alanco TSI Prism system has reduced inmate violence. What Yakuza member could object?

"Inmates know they are being monitored and know they will get caught. The word spreads very quickly," said Alanco exec Greg Oester last year.
