Property 0x03 - Device Serial Number

0x03
Property ID:
Property Type: String
Length: 0 - 15 bytes
Get Property: Yes
Set Property: Yes (Once)
Default Value: Null string / ASCII device serial number set when the device is configured.
The property contains the device serial number, and is 0 to 15 bytes long. The device sends the value of
this property (if any) to the host in ARQC Messages (EMV Only), ARPC Response from Online
Processing (EMV Only), and Transaction Result Messages (EMV Only). This property may be Set
only once; attempts to Set the property again fail with RC = 0x07 (Sequence Error). Note this value does
not necessarily have the same value as Property 0x01 - USB Serial Number (HID Only | KB Only),
which is used mostly for differentiating identical devices after USB enumeration.
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.
