A fingerprinting device checker identifies the characteristics of someone’s hardware and software when they access a website. It can help stop fraudsters and offer detailed insights into anyone who comes onto your site.

The information used to build a fingerprint includes: IP address, browser brand and version, HTTP request headers, the user_agent string, operating system (OS), list of installed browser fonts, client time zone and screen resolution. It also collects data from the device about its software and identifies the device maker, such as Apple for iOS devices and Microsoft for Windows devices.

Using these attributes, companies can create a unique fingerprint for each device that comes to their website and affiliate it with the users of those devices. This enables them to monitor suspicious activity and intervene sooner in the case of fraud or account takeovers.

Checking Device Fingerprints: Fingerprinting Device Checker

For e-commerce sites, fingerprinting can be used to identify potentially fraudulent orders. This is done by analyzing the fingerprint and comparing it to known patterns of fraudulent behavior or blacklisted attributes. If the fingerprint matches one of these, the merchant can flag the order and ask for further authentication from the customer.

The quality of the fingerprints can be improved by ensuring that the scanner and devices are well maintained. This includes avoiding rough usage and cleaning the glass of the scanner with a sanitizer to remove dirt and dust. The fingerprints can be recorded either by using ink to record them on standard cards or electronically with a live scan.
