### Property 0x6E - Mask Service Code (Set Mask Service Code Only) <a href="#toc183604169" id="toc183604169"></a>

| Property ID:   | 0x6E   |
| -------------- | ------ |
| Property Type: | Byte   |
| Length:        | 1 byte |
| Get Property:  | Yes    |
| Set Property:  | Yes    |
| Default Value: | 0x01   |

This property controls the masking of the service code on ISO card tracks 1 and 2. If this property is set to 1, the device masks the service code.  If this property is set to 0, the device does not mask the service code.

The host can use this property to enable Selectable Card Data Encryption. Any of the bits in this property enables the SCDE with the corresponding data field included in the encrypted SCDE.

The M002 message is transmitted to the host instead of the M001 message when the following four conditions are met when a financial card is swiped.

* Any of the defined property 0x78 bits are set to 1 (enabled)
* Card Encode Type of the swiped card is ISO
* Initial SCDE DUKPT Key was injected into the device
* SCDE DUKPT future keys are available (not exhausted)

### Property 0x87 – Key map status

| Property ID:    | 0x87                                 |
| --------------- | ------------------------------------ |
| Property Type:  | Binary                               |
| Length:         | 8 bytes                              |
| Get Property:   | Yes                                  |
| Set Property:   | No – values come from key injection. |
| Starting Value: | 0 – if no keys loaded                |

If a key has been loaded into the device, then it’s bit indicator should be set to 1.

### Property 0x88 - USB Packet Delay <a href="#ref166659560" id="ref166659560"></a>

| Property ID:    | 0x88        |
| --------------- | ----------- |
| Property Type:  | Binary      |
| Length:         | 1 byte      |
| Get Property:   | Yes         |
| Set Property:   | Yes         |
| Starting Value: | 0x00 (0 ms) |

The host can use this property to adjust the device’s USB packet delay.  The property can be set to 0 to have no delay, or it can be set to a specific value in the range of 1 to 255 ms.

* Adjusting this value does not require security when the device is fully configured.
* Adjusting this value does not affect the USB HOST POLL TIMEOUT, PROPERTY 0x52. In fact, it is mostly independent from the polling interval.

MagTek recommends the following values for various platforms:

* Windows = 0x00 (0 ms)
* Android = 0x19 (25 ms)
* Linux = 0x32 (50 ms)
