Via Weblogky. Sounds important for its potential.

“The QR Code is a the next-generation bar code, already popping up here and there. Says Rob Walker in his NY Times Consumed column,
The traditional bar code is most familiar as the Universal Product Code on practically every packaged good we buy. The series of stripes corresponds to a numeric code containing data like an item’s weight and manufacturer. The new generation of code [QR Code; QR=”quick response”] can handle more information because it is arranged in a dot-matrix style that communicates with a scanner both horizontally and vertically — as opposed to the one-dimensional, linear manner of regular bar codes.
Because anyone can generate a QR code for pretty much any data that fits, and because many mobile phones can have readers that interpret the codes, they’re sure to pop up anywhere and everywhere, not just as product inventory codes.”
QR codes are an ok, but give me RFID tags first.
Hi James, could you elaborate?
Actually, both are fine, i’ve just been submerged in RFID recently so perhaps my first answer was not wholly accurate. Most RFID tags do not have a large memory, they are simply a unique id which then will be related to more information on an object via a software application. RFID tags are starting to get memory. The difference is the read speed. RFID tags, depending on type are fast to read and not dependent on getting a correct optical angle for reading.
