Description	The device uses this property to determine what character it should use when sending masked ISO/ABA track data. If the Property 1.1.2.2.1.5 PAN MOD 10 Check Digit Correction is enabled, the masked portions of the track will always be masked with ‘0’. For more information about masking, see the information at the bottom of this section.

When the device sends masked track data, it replaces some characters in the track data with a specified mask character. The specific characters the device masks depends on the card encode type. The device only selectively masks data that came from ISO/ABA cards (Financial Cards with ISO/IEC 7813 Format code B); it sends data from all other card types entirely unmasked.

The device masks all fields from ISO/ABA cards except a number of configurable leading and trailing characters of the PAN. See Property 1.1.2.2.1.3 PAN Number of Leading Unmasked Characters and Property 1.1.2.2.1.4 PAN Number of Trailing Unmasked Characters.

For chip card transactions, masked track 2 data is contained in TLV data object DFDF4D. For magnetic stripe transactions, masked track 1, 2 and 3 data is contained in TLV data objects DFDF31, DFDF33 and DFDF35, respectively.

Table 513 below provides an example of data from tracks 1, 2, and 3 of an ISO/ABA card after it has been decrypted or if the device has sent it in the clear. Table 514 shows the same data as it might appear with a specific set of masking rules applied.
