**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. ## Table - Sample ISO/ABA Track Data, Clear Text / Decrypted
