Post Card String Property (KB, BulleT, UART, RS-232)
Property ID: 0x1F
Property Type: String
Length: 0 – 7 bytes
Get Property: Yes
Set Property: Yes
Default Value: No string with a length of zero.
Description: The value is an ASCII string that represents the reader’s post card string. This
string can be 0 – 7 bytes long. This string is sent after all other card data.
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.
