Scope of the telecommunications services This Recommendation specifies the general, operational and qualitie
9、s-of-service requirements of Electronic Funds Transfer telecommunications services, associated teleservices and supplementary services. The scope of the service is confined to those telecommunications requirements needed to assist the nancial institutions to carry out transactions remotely to their
10、processing centres. It is assumed throughout this Recommenda- tion that the parties involved in Electronic Funds Transfer transactions have agreed to respect the procedures for the service concept, in accordance with the security policy of the financial institutions. The service is described in term
11、s of a range of teleservices, a range of supplementary services to enhance the security and functionality of Electronic Funds Transfer, and a grouping of the supplementary services within the phases of a transaction, see Figures 1 (T/SF 57) to 3 (T/SF 57). Additional Recommendations will eventually
12、address the detailed definitions of the different sub-sets of the service. Neither the main- tenance of the accounts nor the actual transfer of funds between accounts (inter-bank clearing) are part of the scope of this service or its definition. 1.2. Definition of terms For the purposes of this Reco
13、mmendation, terms have the following special meaning: Any establishment either directly or indirectly undertaking banking, e.g. : the management and issuance of cash or negotiable entities and instruments, and the maintenance of financial accounts. Primary users of an Electronic Funds Transfer servi
14、ce other than the financial institutions. Account-holders who are issued with machine-readabIe physical tokens and secret information (Personal Identification Information) with which to execute transactions via an Electronic Funds Transfer service. A typical range of physical tokens is shown in Figu

Relationship with the banking function The Electronic Funds Transfer telecommunications services consist of a family of national or international teleservices and associated bearer and supplementary services provided by Administrations, enab
18、ling users consisting of financial institutions, their agents and account-holders to send and receive messages that convey instructions to transfer funds between accounts, see Figure 5 (T/SF 57), and to provide additional information complementary to, and which assists banking functions. Technical r
19、equirements Some of the technical requirements and protocols that may be used in this service are already defined in the context of other data and telematic services. However, for many of the Electronic Funds Transfer teleservices and supplementary services the technical recommendations do not yet e
20、xist and should therefore be the subject of future harmonisation studies. The EFT terminal The functionality required of the terminal will depend on the capabilities for information processing and storage provided at the terminal. Throughout this Recommendation the functionality of the terminal is d
21、eemed to be the aggregate of the capabilities of the terminal and of the Token. Statutory implications Harmonisation of the Electronic Funds Transfer telecommunications services will permit public interna- tional operation, depending on the degree of international standardisation achieved. Cognisanc
22、e should be taken of any implications inherent in the extension of Funds Transfer services across national frontiers. The currency in which transactions are transmitted It is assumed that the selection of the currency for each international transaction will be a matter for agreement amongst the user
23、s of the service. While the telecommunications service would be expected to convey details about the currency selected for each international transaction, it would not be involved in any way with the exchange from one currency to another, and there should be no interference with the message content.
24、 The implications of the effects of currency control may need to be taken into account in the operation of the service. Any statutory restrictions Restrictions or requirements pertaining to Electronic Funds Transfer in the country of each national Administration need to be known so that the internat
25、ional telecommunications services supporting Elec- tronic Funds Transfer do not infringe national statutory requirements, regardless of whether it is the duty of the financial institutions or the providers of telecommunications services to respect such regulations. The parties to be connected The sc
26、ope of the Recommendation for Electronic Funds Transfer telecommunications services includes connection, transfer of messages and disconnection amongst all, or some of the following: - the account-holder whose account is being debited, - the account-holder whose account is being credited, - the fina
27、ncial institution maintaining the account being credited, - an organisation acting on behalf of, and in relation to the financial institution maintaining the account - the financial institution maintaining the account being debited, - an organisation acting on behalf of, and in relation to the finan
28、cial institution maintaining the account being credited, being debited. Edition of January 15, 1988 CEPT T/SF*57*E 87 2326414 0009461 3 T/SF 57 E Page 4 2. 3. 3.1. 3.1.1. 3.1.2. 3.2. 3.3. 3.4. TELECOMMUNICATIONS SERVICES DEFINITION Electronic Funds Transfer is a telecommunications and payments servi
29、ce in which the data communication and allied processing necessary to carry out financial transactions between accounts held at financial institutions, and any incidental supportive services, are dependent wholly or to an appreciable extent on the general network. The telecommunications services for
30、 Electronic Funds Transfer may rely on combination of public and private networks. Optionally it may also depend on other facilities provided by the Administration such as terminals and network management services. It may also rely on secure communication protocols between the terminals, intermediat
31、e network nodes and the processing centre of the financial institutions or organisations acting on their behalf, and on identification procedures involving machine-readable physical tokens and secret information. TELESERVICE DEFINITIONS The Electronic Funds Transfer teleservices are illustrated in F
32、igure 1 (T/SF 57), along with an indication of the category of users expected to be involved in the transactions. Electronic Funds Transfer at point of sale service (EFTPOS) An EFTPOS transaction is an Electronic Funds Transfer and Payments teleservice in which the transaction takes place at the ven
33、dor?s terminal. It will usually involve the real-time verification that the purchaser is entitled and is able to undertake the transaction. Two cases may occur: Supervised EFTPOS transactions Supervised EFTPOS is the option in which the vendor (or the agent of the vendor) and the purchaser meet toge
34、ther at the terminal to effect a transaction. Unsupervised EFTPOS (Automatic vending machines) Unsupervised EFTPOS is the option in which the purchaser attends at an unsupervised tesminal to effect a transaction. Electronic Funds Transfer for remote vendor service An Electronic Funds Transfer for Re
35、mote Vendor service transaction is a teleservice in which the transac- tion is agreed between the vendor and the purchaser, who are using terminals in different locations, by means of communication via the telecommunications service. Security depends on the certification and secure communication of
36、information via an Electronic Funds Transfer telecommunications service between the purchaser?s terminal and the vendor?s terminal (or processing centre). The security requirements for communication at the terminals will in general be the same as that for EFTPOS. Home banking service Home banking is
37、 an Electronic Funds Transfer and Payments teleservice in which account-holders may transfer funds from their accounts to other accounts by means of the Electronic Funds Transfer telecom- munications service. Security will depend on certification and secure communication of information input at the
38、terminal used by the account-holder and transmitted to the financial institutions, or organisations acting on their behalf who maintain the payee?s account. Automatic Teller Machine Service Automatic Teller Machine service is an Electronic Funds Transfer and Payments teleservice, offered at public b
39、anking terminals, by means of which remote banking services may be provided to itinerant account-holders. I 3.5. Electronic payments for services provided by the telecommunications Administrations The service is an Electronic Funds Transfer and Payments point-of-sale teleservice in which the vendor
40、is the Administration, and the terminal is a telecommunications terminal (see 3.1.2.). Edition of January 15, 1988 CEPT T/SF*57UE 87 H 2326434 00094b2 5 H T/SF 57 E Page 5 3.6. Other Electronic Funds Transfer services Other teleservices exist that are closely related to, or are relatively similar to
41、 the Teleservices described in 3.1. to 3.5. Examples include the non-repudiable purchase of public stock or bonds. 4. PHASES OF ELECTRONIC FUNDS TRANSFER TRANSACTIONS Most Electronic Funds Transfer transactions involve up to three distinct sets of events which are described as the phases of the tran
42、saction: Enquiry, Verication and Execution. The functionality of each phase is described in terms of a range of supplementary services, which are defined in 5. and illustrated in Figure 3 (T/SF 57). 4.1. Enquiry Phase The Enquiry phase is the sequence of events which can take place at any time, in w
43、hich an account-holder can solicit information or non-payment banking services from the financial institutions maintaining the account. Typically, the supplementary services employed in this phase would be: - Token Authentication - Proof of Token-holders authority - Financial institution authenticat
44、ion - Information Request - Electronic Funds Transfer Message Integrity - Audit 4.2. Verification Phase The Verification phase is the sequence of events in which the machine-readable token is authenticated; authority to use the token, terminal and to participate in the transaction is proven; and an
45、indication is delivered of the ability of the account-holder and/or the financial institution maintaining that account to effect a debit of the funds. Typically, the supplementary services employed in this phase would be: - Token Authentication - Proof of Token-holders authority - Financial institut
46、ion authentication - Proof of nancial institution authority - Authorisation Delivery - Electronic Funds Transfer Message Integrity - Audit 4.3. Execution Phase The Execution phase consists of either Payments or Cancellation. It is the sequence of events following the Verification phase in which, if
47、the transaction is possible, details of the transaction are notified to the appropriate financial institutions, and any necessary legal documentation is produced. Otherwise the transaction is cancelled. Typically, the supplementary services employed in the Payments option would be: - Authenticated R
48、ecord of Transaction - Electronic Funds Transfer Message Integrity - Audit Typically, the supplementary services employed in the cancellation option would be: - Cancellation - Electronic Funds Transfer Message Integrity - Audit O Edition of January 15, 1988 CEPT T/SF*57*E 87 m 2326434 O009463 7 m Tf
