As of July 9th, 2012, foreigners in Japan are getting new ID cards. These cards are perfectly wonderful and will make everything so much easier for us we’ll wonder how we ever survived without them. Or at least that’s what websites with cartoony graphics tell me.
What caught my attention is that these new cards are embedded with a small microchip that broadcasts your personal data to anyone with a reader. These are IC chips, which use RFID technology. It’s the same thing in your SUICA train pass, except that you don’t have to hold it up to the reader. Some RFID chips can be read as far away as 30 feet.
