Cyno01: i like the circular thing, that actually makes a lot of sense since a scan just takes basically a 1 dimensional cross section, but i guess now for most things instead of having to rotate the barcode we have the lasers at a bunch of crazy angles or rotating or something
KickahaOta: Cyno01: i like the circular thing, that actually makes a lot of sense since a scan just takes basically a 1 dimensional cross section, but i guess now for most things instead of having to rotate the barcode we have the lasers at a bunch of crazy angles or rotating or somethingActually, the circular thing sounds like a bad idea. One of the advantages of the current rectangular barcode is that it's surprisingly tolerant of damage/stains/smudging/etc.; as long as there's some horizontal path across the barcode that isn't damaged, a decent reader can still read it. In contrast, if the code had been circular, at least a few of the bars would probably be very small, meaning that a small amount of damage could make the code unreadable. Or, in order to make sure the lines had sufficient size to be damage-resistant, the whole code would have to be impractically large -- the sort of thing you could put on a shipping carton, but not on a milk carton.Of course, now we're getting "3D barcodes" (don't get me started on the name), which have small pixels that seem like they should be vulnerable to damage for the same reason. But now barcode readers have gotten sophisticated enough to work around this problem; the 3D barcodes just contain error correction pixels spread out across the code, so that as long as a relatively small area of the code is damaged, the data from the missing area can be reconstructed by the barcode reader based on the rest of the code. You couldn't have done that in 1970.
