Sweden could be pointing the way to a (nearly) cash-free economy.

There are many, many things to dislike about analog money. Cash and coins are unwieldy. They're heavy. They're dirty. They leave no automatic record of the financial transactions that are made with them.

Here in the U.S., despite Square and PayPal and other services that would seem to herald the end of cash, bills and coins still represent 7 percent of our total economy. In Sweden, however -- which ranked first in this year's Global Information Technology Report from the World Economic Forum -- cash is scarcer. And it's becoming, the AP reports, scarcer still. While Sweden was the first European country to introduce bank notes in 1661, it's now come farther than any other country in the attempt to eradicate them. In most Swedish cities, the AP notes,

public buses don't accept cash; tickets are prepaid or purchased with a cell phone text message. A small but growing number of businesses only take cards, and some bank offices -- which make money on electronic transactions -- have stopped handling cash altogether.

Even houses of worship are becoming increasingly friendly to cash-free transactions: At the Carl Gustaf Church in Karlshamn, southern Sweden, Vicar Johan Tyrberg recently installed a card reader to allow worshipers to tithe in digital form.

This isn't, right now, the end of cash -- in Sweden or anywhere else. As Lars Nyberg, the deputy governor of Sweden's central bank, put it last year: Cash will survive "like the crocodile, even though it may be forced to see its habitat gradually cut back." But it may be the beginning of the end. Sweden's innovations suggest a future in which cash is increasingly rare.
