A credit report is a report which contains the detailed credit history and reults of an individual or company. A credit report will show any and all loans applied for as well as successful applications. It reflects also the payment status of how all your accounts are being paid. This is then used to set up your credit profile and will be used as reference by future companies with whom you apply for a loan or finance etc.
With the credit report they work on a merit or point system which will show the lender how you are currently paying your debt, in other words, are you a risk to loan to or not.
The more loans applied for, the more it affects your scoring in a negative way. This is the reason why some banks or finance institutions will request you to re-apply within a few months, this is so that your scoring can get a chance to recover and pick up.
