Please note: this article is only intended for the HiPay Enterprise Direct POST integration.
The device fingerprint identifies devices through information collected by a client run on an end user’s computer.
This client generates a black box that contains all the available device information.
Web applications obtain device information by sourcing dynamically generated JavaScript from HiPay Enterprise. The JavaScript determines what information is available and generates a black box from all available sources.
Black box content
A black box will typically:
- Range up to 4,000 bytes (the average length being just under 1,000
bytes) - Contain alphanumeric values and the following special characters: + / ; =
- Begin with 0200, 0400, 0500 or 0600
Generating black box content
To integrate the client, you must specify a hidden field that the JavaScript will populate.
This adds the black box as another field to be submitted along with the other details in the form.
What TO DO |
What NOT TO DO |
1. You MUST INCLUDE a hidden form field with an “ioBB” ID that will be populated with the value.

Example of black box generation
<form name="test"> <!-- hidden field to store black box --> <input type="text" name="device_fingerprint" id="ioBB"> </form> <!-- Include JavaScript fingerprint library --> <script language="javascript" src="https://secure-gateway.hipay-tpp.com/gateway/toolbox/fingerprint"> </script> |
