Rainbow inkless fingerprint is a clean, modern method of taking a fingerprint. With this type of individual identification, the messy inkpads of the past are no longer necessary. A special inkless fingerprint pad is used to take impressions, rather than a traditional inkpad. Sometimes, special paper is also used to record prints.

Employers frequently opt for inkless fingerprint systems, which can assist them in performing background checks on potential and current employees. By eliminating the mess of traditional fingerprints, inkless systems can be more convenient and easy to use in a variety of settings.
