    MONEY

    Smart Banknotes

    A proposal for bank notes that bridge the gap between physical and

    electronic money.

    By Ignacio Mas

    text:

    Cash imposes large costs on society, yet it is hard to envision

    moving to an entirely cashless society. If we cannot get rid of cash,

    then we need to change it in a way that makes it less costly for all to

    handle.

    A new kind of smart banknote could be created that can be

    activated or deactivated electronically; you would transfer value

    between a banknote and your bank account, right from your mobile

    handset. Deactivated cash could be transported cheaply; stores could

    make their accumulated cash balances vanish at will by simply

    deactivating it; and bank customers would be able to convert their bank

    account into cash or vice versa anywhere, anytime.

    With these new smart banknotes, mobile banking could flourish in

    developing countries without requiring complex and costly cash agent

    networks. In this fashion, the mobile handset can truly integrate the

    capabilities of an Internet banking terminal and an ATM.

    A large portion of the population depends on cash as a form of

    saving and as a means of exchange, but there are three big problems

    with it:

    Cash is not easily used for remote payments, such as sending

    money to your college kid in another state.

    It is difficult for people to hang on to small cash balances

    beyond pure pocket money. As a store of value, physical cash creates

    problems of self-discipline and security.

    It is unsafe to transport and travel with cash.

    Cash handling also imposes a large cost on banks, and this high

    cost critically constrains the ability of banks to increase the

    capillarity of their distribution networks (through branches or ATMs).

    Banks transfer the cost onto customers by requiring them to travel to

    more distant cash aggregation centers. This may not be much of a

    problem in developed countries where banks have deployed a dense

    network of branches and ATMs to cater to their customers cash needs,

    but this infrastructure is largely lacking in slums and rural areas in

    developing countries.

    Despite these problems, cash has benefits that electronic money

    cannot deliver: It is universally accepted. Transactions are quick. The

    bills are of fixed denomination (unlike payment cards, which are linked

    to variable account values), making them very useful for limiting the

    amount of money you risk spending (or losing) when you take a trip to

    the casino, for instance, or out on a late-night jog. And of course

    cash can be used anonymously, while electronic payments always leave a

    trail.

    The advantages of electronic money are virtually the flip side of

    the advantages of cash: E-money consists of storable and readable

    information, and its transactions are transparent and traceable. While

    electronic money will inexorably displace cash, electronic money and

    cash will need to coexist at least into the medium term. Thats

    particularly true in developing countries, where there is a tiny

    installed base of acceptance devices.

    If we cant get rid of cash, then we need to change it in a way

    that makes it less costly for all. It is figuring out the interface

    between these two forms of moneycashing into and cashing out of

    electronic moneythat will be the key.

    Bridging the Gap between Cash and Cashless Systems

    Imagine a new generation of bills embedded with a radio-enabled

    chip that could communicate at close range with a mobile phone or a

    point-of-sale (POS) device. The chip could essentially turn the bill

    on or off, and that bills state would somehow be visible to the

    user (e.g., its color might disappear when the bill is off and

    reappear in full splendor when it is on).

    Cash could then be transported at low cost in its deactivated

    form. In order to be used, bills wouldneed to be activated by

    electronically transferring value to them from a bank account. Users

    could do that by passing their bills over their radio-equipped mobile

    phone or at an enabled POS terminal, and agreeing to a transfer of

    value from their bank account to the bill. Like any debit transaction,

    this would be authorized and recorded in real time by the users bank.

    The process could also be reversed: Bills could be deactivated by

    having their value transferred back (i.e., credited) to their bank

    account. There would be a security protocol ensuring that, when one

    source of value is credited (e.g., activating my cash bill), another

    one must be debited (e.g., my bank account).

    In this fashion, the mobile phone truly becomes an ATM. People

    would be able to instantly deposit money into their accounts and create

    immediate liquidity from their bank accounts, without requiring any

    banking infrastructure in their neighborhood. Bills would be like

    prepaid cards that have value loaded and expended, but unlike prepaid

    cards they would remain of a fixed denomination. In their active state,

    they would be tradable without requiring a card reader. In their

    deactivated state, they could be distributed very cheaply, and stacks

    of deactivated bills could be purchased for pennies at the supermarket.

    With these smart banknotes, monetary authorities could reduce

    the security costs of producing and distributing cash because it could

    be handled in its deactivated form through normal distribution

    channels. The chip would offer a higher level of security on the bills,

    as it would be able to hold an encrypted unique serial number. The

    validity of bills could be established unequivocally in real time.

    Implementing this scheme would require central banks to issue

    these new smart banknotes. There is a long tradition of embedding new

    technology into bills, such as anti-counterfeiting holograms, so this

    scheme would fit in the natural evolution of physical currency. The

    issuance of new bills can also be gradual; new and old bills could

    coexist.

    Security standards will be needed to ensure that activation or

    deactivation of the smart banknotes would be through authorized devices

    and authorized accounts. In addition, the scheme would require a

    deployed base of cash-activating devices (mobile phones or POS

    terminals), with real-time connectivity to banks for banking

    transactions, RFID capabilities to interact with cash bills, and loaded

    with the bill management application.

    So far, all attempts to eradicate cash by replacing it with

    electronic forms of money have failed. People dont want to entirely

    let go of the physicality of cash. Moving toward the much-vaunted

    cashless societyis often invoked as a social-engineering task. While

    technology can be an instrument to change society, it seems

    unreasonable to change society so that we can adopt technology. So

    lets change our banknotes instead.

    In fact, this scheme is in the historical tradition of issuing

    pieces of metal as coins by the act of stamping a wedge (Latin:cuneus,

    from which the word coin is derived) on them. The wedge activated

    them in the sense of certifying their value.

    The author would like to thank Paul Makin and Andrew Whitcombe of

    Consult Hyperion for their work in assessing the technical feasibility

    of the smart banknotes described here. They in fact came up with the

    term smart banknote.
