Automatic Identification and Data
Capture (AIDC)

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)



AIDC Technologies - correct answer - optical (bar codes, optical character recognition, machine vision)

- electromagnetic (radio frequency identification (RFID))

- magnetic (data encoded magnetically, similar to magnetic tape)

, AIDC Technologies (continued) - correct answer - smart card (small plastic cards imbedded with
microchips)

- touch techniques (touch screens)

- biometric (voice recognition, fingerprint analysis, retinal eye scans)



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)
