Why dont we put a barcode on EVERYTHING manufactured?
I like the idea of taking some random "part" to the hardware store and instantly finding it in a database. Of course, thisis
only the tip of the iceberg of applications.
Some limitations of current barcodes would have to be
overcome to make
this feasible. For starters the directionality
and large size are problematic. To this end, I propose that
future barcodes be microfiber-based (like the little filaments
in dollar bills). The fibers contain metallic segments. When
struck with an intense RF pulse, the fiber reradiates a
spectrum of RF waves that are decoded into a string of
digits.

Given that it apparently cheaper to throw most items away (and buy a new one) than get them repaired, that's why. |

You might want to do a quick search for 'barcode' here at the HalfBakery. 'RFID' would be another good term to search on. My last request is that you search for the proper category before posting. |
