A credit score is a numerical expression based on a statistical analysis of a person\'s credit files, to represent the creditworthiness of that person. A credit score is primarily based on credit report information, typically sourced from credit bureaus.
Lenders, such as banks and credit card companies, use credit scores to evaluate the potential risk posed by lending money to consumers and to mitigate losses due to bad debt. Lenders use credit scores to determine who qualifies for a loan, at what interest rate, and what credit limits. The use of credit or identity scoring prior to authorizing access or granting credit is an implementation of a trusted system.
Credit scoring is not limited to banks. Other organizations, such as mobile phone companies, insurance companies, employers, and government departments employ the same techniques. Credit scoring also has a lot of overlap with data mining, which uses many similar techniques.
