If you are still in the habit of yanking out important documents (birth certificates, driving license, marriage certificate, income tax statements, education certificate etc) from your drawer and make photocopies each time it is required, consider digitize them for some convenience.
Most of the time, original document is not required when you apply for a job, credit card or a bank loan. If you have digital copies, you can simply print out the relevant documents instead of photocopying, and easily email the documents as attachments when required.
We recommend you to scan the documents at 600dpi resolution and save them in PDF format. This high resolution is good enough for print out copies. Keep a version of the documents at a lower 150 dpi resolution, use this smaller-size version when you need to email the documents to save some bandwidth.
