3.10. Plessey
This was the first bar code symbology invented in the UK during the early 70's to control
the loan of library books.
The character set is numeric and its encoding system is very simple (thin bar = 0, large bar
= 1). It can be only read with two check digits as last characters.
3.11. Telepen
Mainly used in UK, this symbology has two separated sets of characters; one is numeric
and the other is alphanumeric. Use the codes below to activate the set desired.
3.12. Code 93
The 128 ASCII characters can be encoded using this symbology which is more dense than
Code 39. Two check digits are always encoded as the last characters and are verified by
the decoder but not transmitted.
Its Multiread function permits the concatenation of codes in the decoder for those that start
with a space character. These will be transmitted upon the reading of a code having no
leading space character.
