EAS Function
The LSB of Byte 1 in Block -2 holds the EAS bit (Electronic Article Surveillance
mode active – the label responds to an EAS command)
Table 8 - EAS
EAS: e = 1 (EAS enabled) e = 0 (EAS disabled)
Application Family Identifier
The ICODE system offers the feature to use an Application Family Identifier
(AFI) at the inventory command and the two custom commands inventory read
and fast inventory read (this allows for example the creation of label families).
This 8-bit value is located at Byte 2 in Block -2 as shown in the following figure
and is only evaluated if the AFI flag is set in the reader command.
Table 9 - AFI
Data Storage Format Identifier
The Data Storage Format Identifier (DSFID) is located at Byte 3 in Block -2.
