Although I stongly share your overall beliefs in the superiority of digital bearer certificates (DBC), I am much less certain about the intrinsic financial cost differentials. Let's first consider credit cards (CCs). Consumers using CCs, if they choose their bank/agent carefully and settle their monthly statements in full and promptly, pay nothing (directly) for the priviledge of using the cards. One can argue that merchants build the cost of their CC transaction clearance costs into their price structure and therefore every patron, whether using cash or CC, pay for the costs of CC usage (few merchants offer cash discounts). Most walk-in retail merchants, in good standing, pay about 2% in discount (fees). On-line and mail order merchants pay about 3% as do those with a higher rate of chargebacks and/or in grey businesses (e.g., on-line gaming and adult entertainment). These fees represent the costs of operating the CC clearing system (MC, VISA, AMEX, etc.) the bank's overhead and profit. Now let's look at Automatic Clearing House (ACH). ACH is a Federal Reserve service offered by 18,000 financial institutions to 40,000 corporations and generating 2.5 billion transaction per year. It is used by business to pay employees (automatic payroll deposit), automatic debt of consumer checking accounts (periodic payments) and business-to-business transactions (a primitive EDI). Costs of the service are born entirely by the business and rates vary considerably, depending upon volume and depth of business relationship with the bank or service company (e.g., ADP) and how much of the ACH pre-process work is automated or performed by the business. Charges are generally below $0.25 per transaction. The amount of back office processing required for ACH is not inherently different than for CCs. However, there is a significant difference in amount of marketing and distribution costs. It is not unusual for a bank to pay $50-60 to acquire a new CC customer. Compared to the massive CC consumer branding campaigns, there's not much marketing overhead in ACH. Whereas ACH is highly automated and all report generation is already included in the checking account fees (both business and consumer), CCs are often an additional and costly overhead. This is one reason the larger banks have been moving to integrate their consumer relationships into a single monthly statement (e.g., Citibank's "CitiOne"). When clients are convinced that electronic statements over the Net are acceptable this overhead will shrink considerably for both services, but will not be anywhere near zero. Will DBC systems will have lower marketing costs than CC or ACH serving similar customer bases and applications? I think not. Indeed, the case could be made that in order for DBC to gain widespread acceptance over ACH or CC marketing expeditures might need to be consideable. It is not clear that the back office costs of running a mint are any cheaper than a book-entry system (e.g., control and auditing requirements to meet Generally Accepted Accounting Principles and establish/maintain trust) and you still need the book-entry system to occassionally transfer value; to the extent that digital bearer certificates become accepted as legal tender costs should decline, but the regulatory issues increase. However, the ACH and CC system's prices reflect the substantial Fed and CC backbone cost and profit to run their private networks, and it is here that costs for on-line digital bearer certificate systems will have and edge for some time. When one combines the transactional economic advantages of DBC: no customer accounts, statement generation, little or no need for dispute resolution and the economies of using the Net for settlement, with the still considerable marketing costs, the likely differential between DBC and CC/ACH is closer to one order of magnitude at best. This is still considerable, however, and if properly branded and marketed could significantly displace current competition, for lower value transactions. The overhead of CC discounts is keenly watched by merchants. If a trusted DBC issuer/agent offered 1.0% fees (especially to on-line merchants) it would get noticed quickly. --Steve PGP mail preferred Fingerprint: FE 90 1A 95 9D EA 8D 61 81 2E CC A9 A4 4A FB A9 Key available on BAL server, http://www-swiss.ai.mit.edu/~bal/pks-toplev.html --------------------------------------------------------------------- Steve Schear | tel: (702) 658-2654 CEO | fax: (702) 658-2673 First ECache Corporation | 7075 West Gowan Road | Suite 2148 | Las Vegas, NV 89129 | Internet: azur@netcom.com --------------------------------------------------------------------- "I know not what instruments others may use, but as for me, give me Ecache or give me debt."
