9.9 Property 0x08 - AAMVA Track Mask (MSR Only)
Property ID:
0x08
Property Type: String
Length: 6 bytes
Get Property: Yes
Set Property:
Yes
Default Value:
“04040Y”
This property specifies the factors for masking data on AAMVA type cards. Each byte in the property
has the following meaning:
Offset Description
0..1
These bytes are an ASCII representation of a decimal value that specifies how many of the
leading characters of the Driver’s License/ID Number (DL/ID#) the device sends unmasked.
The range is from “00” to “99”.
2..3
These bytes are an ASCII representation of a decimal value that specifies how many of the
trailing characters of the DL/ID# sends unmasked. The range is from “00” to “99”.
4
Masking Character. This byte specifies which character the device uses for masking. If this
byte contains the uppercase letter ‘V’, the following rules apply:

The device masks the PAN according to the rules of this property ( Property 0x34 - Send
AAMVA Card Data is ignored)

The device uses ‘0’ for masking the PAN

The device sends all data after the PAN without masking
5
This byte specifies whether the device applies Mod 10 Correction to the DL/ID#. “Y” means
Yes, “N” means No. This option is only effective if the masking character specified in this
command is “0”.
This property is stored in non-volatile memory, so it persists when the device is power cycled. When this
property is changed, the device must be reset (see
Command 0x02 - Reset Device ) or powered off for at
least 30 seconds, then powered on, before the changes will take effect.
