The number of times a loan needs to be photographed with a banker may vary depending on the bank or loan type. Generally speaking, when applying for a loan, you need to have an on-site interview and sign relevant documents, which usually requires at least one photo. If you need to make additional loan applications or changes during the loan period, you may need to take another photo to verify your identity and authorization. Some loans may require you to provide additional documents or evidential materials, which may also require your bank personnel to take multiple sets of photos.
