CRC Flag Property (KB and Serial Models)
Property ID: 0x19
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 0x01
Description: This property is defined as follows:
0 0 0 0 0 0 E S
E 0 – The Encrypted CRC will NOT be sent
1 – The Encrypted CRC will be sent
S 0 – The Clear Text CRC will NOT be sent
1 – The Clear Text CRC will be sent.
This property is used to designate whether or not the Encrypted and/or the Clear Text
CRC will be sent as part of a card swipe message. In the default state of this property,
the device will send only the Clear Text CRC. When these fields are omitted, the
Programmable Field Separator that precedes each of these fields will be sent anyhow.
This property is stored in non-volatile memory, so it will persist when the unit is power
cycled. When this property is changed, the unit must be reset (see Command Number 2)
or power cycled to have these changes take effect.
