5.2 Card data usage A magnetic stripe card (credit or debit) may be identified by either Track 2 (bit 35) or Track 1 (bit 45). The developers of this part of X9.1 04 concurred that Track 2 is in more prevalent use and is therefore used in the examples. Track 1 may be used either with Track 2 or in place of Track 2; the choice is subject to bilateral agreement. Data from a RFID device or ICC is contained in ICC system related data (bit 55).
5.3 Transaction specific data ISO 8583 provides the data element Transaction specific data (bit 1 04) for data related to the non-financial aspects of a transaction. It also defines specific dataset identifiers for specific industries. Dataset identifier 1 04- 78 is defined for Fleet card data, see 5.3.3. In this part of X9.1 04, dataset identifier 1 04-C1 Bill payment data is defined for national use to exchange data related to bill payment transactions, see 5.3.6.
5.3.1 Product data (bit 63) Product data is the detailed information on the products purchased or selected by the customer. One of two data elements may be used to provide this information. Product data (bit 63) is a private use data element that is defined for those implementations that do not support the secondary bit map, see 5.3.1 . It may be used instead of Fleet card data (bit 1 04-78). See X9.1 04 Part 1 for the mapping of Fleet card data to Product data. In the Product data data element each product is represented by five sub-elements; product code, unit of measure, quantity, unit price and amount. The variable length fields and the succeeding entry are separated by a back slash (\).
The maximum number of products is implementation specific. The product code also identifies whether or not the sale amount is negative. Negative items such as coupon or split-tender are items that reduce the total amount of the transaction. All values are entered as positive numbers: quantity, price or amount.
The product code identifies which values are negative. The sum of the amounts in the product data must equal the transaction amount. The values of the Quantity (68-5) and Unit price (68-6) may have a value that includes both integer and fractional values. The format of these fields consists of a single digit, which specifies the number of fractional digits following the integer, followed by the numeric value. The value must be numeric. The Amount data element may have fractional digits. The number of fractional digits is specified by the currency code. The default value is two fractional digits for U.S. dollars, currency code 840 or USD. Table 1 shows the format of Product data.
