You will not be asked to physically send any documentation; this can easily be done online. Applying for a loan online is a quick process. Most lenders will request proof of identification, address or income before proceeding with your application. For example, if you have recently moved to a new address, then you are more likely to be asked for this information. You will be asked to sign a digital contract to confirm you agree with the Terms and Conditions of the loan repayments.
