Submitting Card-Present (SWIPE) Transactions

Payflow Pro supports card-present transactions (face-to-face purchases).

Follow these guidelines to take advantage of the lower card-present transaction rate:

z Contact your merchant account provider to ensure that they support card-present

transactions.

z Contact PayPal Customer Service to request having your account set up properly for

accepting and passing swipe data.

z If you plan to process card-present as well as card-not-present transactions, set up two

separate Payflow Pro accounts. Request that one account be set up for card-present

transactions, and use it solely for that purpose. Use the other for card-not-present

transactions. Using the wrong account may result in downgrades.

z A Sale is the preferred method to use for card-present transactions. Consult

with your acquiring bank for recommendations on other methods.

Supported Processing Platforms

Card-present Transaction Syntax

Use the SWIPE parameter to pass the Track 1 or Track 2 data (the card’s magnetic stripe

information). Include either Track 1 or Track 2 data—not both (up to 80 alphanumeric

characters). If Track 1 is physically damaged, the POS application can send Track 2 data

instead.

The track data includes the disallowed = (equal sign) character. To enable you to use the data,

the SWIPE parameter must include a length tag specifying the number of characters in the

track data. For this reason, in addition to passing the track data, the POS application must

count the characters in the track data and pass that number. Length tags are described in

“Using Special Characters in Values” on page 19. The length tag in the following example is

[40].

Do not include the ACCT or EXPDATE parameters in card-present transactions, as this data is

included in the SWIPE value.

Example Card-present Transaction Parameter String

This is an example card-present transaction parameter string:

1 2 ... 31 32 33 34 35 36 37 38 39 40 41 ... 73 74
