Background Verification
Is there a gap between the education and address details submitted by your employee or one of your business partners? Are you about to give a loan to someone but you want to double-check whether the qualifications and the address details submitted by the person taking your money can be confirmed or not? This sort of verification is to find small details that can cascade into a bigger problem.
For example, a person has claimed that he stayed at a particular address for six months whereas; he has stayed there only for a couple of weeks. Whether this matters or not, depends on what sort of partnership you are getting into with that person.
