automatic identification and data capture (AIDC) - correct answer - family of technologies that
provide direct entry of data into a computer or other microprocessor
reasons for using AIDC - correct answer - data accuracy
- timeliness
- labor reduction
AIDC applications - correct answer - retail sales and inventory control
- material handling
- factory operations
alternatives to AIDC: manual methods - correct answer - problems with manual collection and data
entry:
1) human errors (when data entered manually)
2) time factor (manual = time consuming, time delay)
3) labor cost (cost of full-time attention of human worker)
components of AIDC - correct answer - data encoding (alphanumeric characters translated into
machine-readable form)
- machine reading or scanning (scanner reads encoded data and converts it to alternative form)
- data decoding (electrical signal transformed into digital data and finally back into original alphanumeric
characters)
measures of AIDC reading accuracy - correct answer - first read rate (FRR)
- substitution error rate (SER)
first read rate (FRR) - correct answer - probability of a successful (correct) reading by the scanner in
its initial attempt
substitution error rate (SER) - correct answer - probability of scanner incorrectly reading the encoded
character as some other character
- in a given set of encoded data containing n characters, the expected number of errors = S E R
multiplied by n
bar codes are of two basic types: - correct answer - linear (1D)
- two-dimensional (2D)
linear (1D) - correct answer - encoded data are read using a linear sweep of the scanner
two-dimensional (2D) - correct answer - encoded data must be read in both directions
two forms of linear bar codes - correct answer - width-modulated
- height-modulated
width-modulated - correct answer - symbol consists of bars and spaces of varying width
- mostly widely used (i.e. universal product code)
