This property specifies whether and how the device returns a SHA-x Hash code with swipe data. See
section 6.18 SHA-1 Hashed Track 2 Data (HID | TLV | GATT | SLIP, SHA-1 Only).
The possible options are:
Value
0x00 Device sends a SHA-1 Hash code of all Track 2 data
0x01 Device sends a SHA-1 Hash code of the Track 2 PAN
0x02 Device sends a Salted SHA-1 Hash code of all Track 2 data
0x03 Device sends a Salted SHA-1 Hash code of the Track 2 PAN
0xFF Device does not send any Hash code
Some devices are configured to only allow the manufacturer to modify this property.
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.
