Extended Code 93 can be used in all the applications where Code 93 is used. It can be used in manufacturing, military, and health applications.
Code 93 Full ASCII can use upper and lower case letters and digits giving itself more data to encode.
Requires specialized scanners, not all handheld scanners support Code 93 Full ASCII.
Code 93 Extended is based on Code 93 and can encode all 128 ASCII characters. The characters represented by Code 93 are represented in Extended Code 93 as single barcode characters, but all other characters are represented by a control character plus another character.
In Code 39, four of the characters ($, %, /, and +) are used to optionally encode all 128 characters-but there is no way to know whether those characters are being used as shift characters in Full ASCII mode or whether they are being used to represent $, %, /, and +. In Code 93 this problem is solved by reserving these four special characters exclusively to "shift" into Full ASCII mode.
One can use Label Flow™ barcode software for printing Code 93 labels or use Asset Track (inventory software) for managing inventory.
