Benefit of auto id
Provide visibility
Less waste
Reducing resources
Better customer service
Just in time manufacturing
Different types of aidc technologies-list them
Barcodes
Biometrics
Card technologies
Optical technologies
Radio frequency identification
Evaluate transit tickets- what technology is best (rfid, tokens, smart cards)
Aidc technologies are complementary or not?
Linear barcodes
What is a linear barcode?
A linear barcode encodes data on the x axis (bottom) so it doesn’t matter where on the y axis the bar code is scanned, the data will always be the same
-describe an element
An element is either a bar or a space
Narrowest element is a module
-x dimension
The width of a module is called an X dimension
vertical redundancy
Linear barcode encodes data in the x axis. Therefore the data is the same regardless of where on the y axis the data is scanned. This is called vertical redundancy.
understand relationship between modulus elements and x dimension
The width of a module is called an X dimension… Measured in mils…
3X is wide…. X is narrow
Width of a module is an x dimension
understand the inter character gap
Intercharacter spacing is between the characters IIIiI (gap) IiiI (gap) iIiIi
inter character gap serves as a break between the characters of a discrete encoded bar code… The width of the gaps should not be more than 4x dimensions
understand the relationship of barcode and bar code data density and … continuous, discrete barcodes.. One has something that the other doesn’t
Discrete barcode for example (code 39) has a very limited data density which is a drawback.. Continuous has greater data density
-determination bar. What type of symbology has one of these?
UPC?
is there a relationship between discrete, width, delta continuous encoding?? Which symbology is that?
Continuous 4 widths
