b – QR Code
Description QR Code is a matrix symbology, defi ned in AIM International
ITS/97-001.
Basic characteristics for QR Code:
QR Code can be encoded as
two models; Model 1 Model 2
Model Version original enhanced
Symbol size in cell, (increment
of 4 cells) 21*21 to 73*73 21*21 to
177*177
1. Numeric data mode: Digits
0-9;
Max: 1167 char Max: 7089 char
2. Alphanumeric data mode:
Digits 0-9; upper case letters
A-Z; nine other characters
Max: 707 char Max: 4296 char
3. 8-bit byte data mode : JIS
8-bit character set (Latin and
Kana) in accordance with
JIS X 0201
Max: 486 char Max: 2953 char
4. Kanji data mode :
Shift JIS X 0208
Max: 299 char Max: 1817 char
5. Mixing mode: Mix of mode
1-4 above
NA Applicable
Note: Th e maximum data length in
ESim is approximately
780 bytes.
Error correction:
Four levels of Reed-Solomon error correction allowing recovery
of:
L 7%
M 15%
Q 25%
H 30%
Masking (intrinsic):
Th is enables the ratio of dark to light modules in the symbol
to be approximated to 1:1 whilst minimizing the occurrence of
arrangements of close modules which would prevent effi
cient
decoding.
