Bar codes are line-of-sight technology, which means people usually have to orient the bar code towards a scanner for it to be read. Radio frequency identification, by contrast, doesn’t require line of sight .
RFID tags can be read as long as they are within range of a reader.
Bar codes have other shortcomings as well. If a label is ripped, soiled or falls off, there is no way to scan the item.
Standard bar codes identify only the manufacturer and product, not the unique item. The bar code on one cylinder is the same as every other, making it impossible to identify which one might pass the inspection.
Assuming the input is a series of 1 followed by 0, the modulated signal amplitude will alternate between 5V and 1V. So we can model this case by applying an input signal of lower frequency to give the envelope detector enough time to discharge.
