What percent of the industry still submits/processes hand-written applications (bank/processing) by email PDF or FAX?

Why have we not fully embraced the digital age? This industry has supposedly found ways to leverage technology to make it economically feasible to market to, underwrite, and finance small dollar deals ($10K-$150K). Seems like as a whole there is still much work to be done on the technology side.

Where's the disconnect? [Merchant - Agent], [Agent - Funder]?

Are merchants not savvy (or trustful) enough fill out a complete digital or online application and sign electronically?

Do those funders who have all the technology on their end find agents and merchants who are willing to do the data entry in order to get a fast response?
