Frank Trotter has a dream: that a newfangled form of electronic money,  known as Ecash, will become the dominant payment mechanism for the   Internet. If the dream comes true, his relatively obscure Midwestern bank   could go down in history as the institution that launched Ecash, Digicash   Corp.'s entry in the Internet payments sweepstakes, to national and perhaps   global prominence.   Long as the odds may seem, "I have lately become a missionary for Ecash,"   said Mr. Trotter, 41, a vice president at Mark Twain Bancshares of St.   Louis.   Mark Twain announced its Ecash program last October, giving the system a   coveted foothold in the United States though with a bank far smaller than   the ones Amsterdam-based Digicash had expended most of its efforts   soliciting.   The Missouri-based bank says it has legitimate business reasons for   making a wager on Ecash. It has an active international department that   sells deposits in multiple currencies. Ecash, the bank reasons, can add a   new dimension to its service and lift Mark Twain into the same league as   other potential issuers and processors of Internet currency.   But at $2.8 billion of assets, Mark Twain clearly lacks the power and   heft of megabanks like Wells Fargo & Co. and First Union Corp., which have   staked out strong positions on the Internet frontier in alliances with   Cybercash Inc., a Digicash competitor.   Among other cyberspace payment mechanisms jockeying for position and for   alliances with banks are: Mondex, the smart card and electronic cash system   backed by National Westminster Bank of London; and First Virtual Holdings,   which has designed a clearing system using electronic mail rather than the   Internet because it doesn't yet trust the security of the latter.   Mark Twain's motivation is simple: "To gain new customers," said Frank   Szofran, head of Mark Twain's capital markets group and supervisor of Mr.   Trotter. "Payments and exchange over the Internet and through electronic   media certainly seem to be the way the world is headed, and we would like   to be a part of it."   While many bankers believe that credit cards and electronic checks will   emerge as the preferred payment choices on the Internet, Mr. Trotter found   himself drawn to Ecash.   He said he shares a "philosophical belief" with the creators of Ecash   that the remitters of on-line payments should be as anonymous and   untraceable as people who choose to use paper currency and coins.   When a Mark Twain depositor purchases Ecash, the amount is transferred   from a regular account to the customer's computer drive. The electronic   money appears on the screen in the form of cyber coins.   An icon on the computer screen continuously indicates how much money the   account contains. When a customer buys a product offered by an on-line   merchant who accepts Ecash, the icon registers the deduction.   Critics of the Ecash technology, championed by Digicash's computer-   scientist chief executive officer David Chaum, say it is too difficult to   use and too expensive to attract a popular following.   "People don't like to have to 'buy' cash," said David E. Weisman, an   analyst at Forrester Research, Cambridge, Mass., who has studied the Ecash   trial.   Nonetheless, Mark Twain's announcement caused a big stir on the   Internet's World Wide Web (address: www.marktwain.com) and interest has   been so strong that the bank hired two people exclusively to field   inquiries.   "About 1,000 people actually have accounts now and we expect 10,000 by   April or May, when we'll have more merchants signed up," Mr. Trotter said.   For Mark Twain, a 30-year-old bank with community and small-business roots,   the link with Digicash was one of many steps it has taken to shed the old   homespun image. It has offices in three states, a stellar lending record,   and streams of fee income from brokerage, commercial finance, and trust   activities.   The payoff can be seen in such fourth-quarter performance indicators as a   1.75% return on assets, 18.36% return on equity, efficiency ratio of 53%,   and 4.85% net interest margin.   "Nothing surprises me with Mark Twain they're always trying to push   things," said Joseph A. Stieven, an analyst at Stifel, Nicolaus. The   company's president, John P. Dubinsky, "really encourages that."   Mr. Trotter, a 15-year veteran of Mark Twain, has spearheaded the bank's   drive to offer innovative niche products, including FDIC-insured savings   accounts and certificates of deposit in foreign *currencies. His interest   in serving international customers and his belief that electronic   transactions should be kept private led him on the trail to Digicash   founder David Chaum.   Mr. Chaum, an authority in the field of cryptography, is as famous for   advocating privacy rights as for the technologies he has developed. His   sales calls on many major banks elicited tepid responses.   Mr. Chaum and Digicash were at first wary of joining forces with a less   prestigious regional like Mark Twain.   "We called Digicash, and it took a little while for them to take us   seriously," Mr. Trotter said.   Mr. Dubinsky, the bank's president and chief executive, said its   reputation as a developer of computer and foreign currency products helped   Digicash take it seriously.   In addition, Mr. Dubinsky said, "being a medium-sized bank, we have a much   quicker decision-making process than a lot of the larger banks" and were   able to give Digicash a quick green light.   Now, for an $11 setup fee and $1 a month surcharge, Mark Twain customers   can buy Ecash in dollars and store it on their computers.   Promoters of Ecash say the system is particularly useful for buying items   that cost $1 and under, for which a credit card charge would be cumbersome.   But there is, as yet, very little to buy with Ecash.   Mark Twain officials say they are busy signing up merchants including   national retailers to correct what they concede has been a shortage of   available products. By late January, only 25 merchants accepted Ecash and   more than 125 were "in the process of bringing up their sites," Mr. Trotter   said.   Among the first merchants to sign up was Maryland Public Television.   "Right now all we're selling on our site is some poetry and songs as a   test," said David Levine, president of Husky Labs, which is coordinating   the experiment for Maryland Public Television. "We make a few pennies a   day."   The station will soon begin accepting Ecash for more popular products,   including transcripts of Wall Street Week and copies of Louis Rukeyser's   stock market predictions.   Mr. Levine said another Husky client, Los Angeles-based Pentagon CDs,   will join the system soon, offering 150,000 compact disks and cassette   tapes for Ecash.   Right now the system is a "closed" one. Customer and merchant both must   have accounts at Mark Twain, and the Ecash transaction amounts to a simple   transfer of funds. Mr. Trotter believes the day will come when buyers and   sellers will be able to do business in Ecash no matter where they bank.   Mr. Dubinsky said he "couldn't be more pleased" with how the experiment is   going.   Mr. Szofran added, "This opens up a whole world of international   customers to a small Midwest bank."   But at Digicash, Mr. Chaum took a more modest view.   "The Mark Twain thing is being pursued more as a marketing experiment   than as a rollout," he said. "I don't want to be uncharitable, but I don't   think you should see Mark Twain as indicative of our strategy."   The Mark Twain trial marks the first time that Ecash has gone truly live,   representing "real money." Sweden Post, which operates Sweden's post office   banking and payment system, is scheduled to begin a similar service later   this year.
