SMART : BackgroundThe Bank of Thailand (BOT) developed inter-bank retail fund transfer system called 'Media Clearing' which started operation on 16 January 1997, to eliminate the limitaion of inter-bank funds transfer in the past that a payer and a payee had to open deposit accounts at the same bank. Media Clearing is designed for an off-line system using electronic media such as magnetic tapes and diskettes.Later, the BOT enhanced the system to transfer data via on-line by using web technology and changed the name from 'Media Clearing' to 'SMART' (System for Managing Automated Retail Funds Transfer).SMART operates on both on-line and offline basis to accommodate services with large volume, advanced agreement and regular payment interval.The Electronic Clearing House (ECH) acts as the center for receiving, sorting retail funds transfer data and calculating net balance for interbank settlement.

1. Credit Transfer is a funds transfer from customer's account at one bank to another account at different bank. these services are such as;
Salary paymentDividend payment,Tax refund payment,Interest payment, etc.

Media Clearing operation procedureMedia clearing operates on an off-line basis of which transaction information is stored on electronic media such as magnetic tape or diskette. Companies have to contact the commercial bank for a detailed regulation and a contact. The bank will stored the information of customer’s debit/credit funds transfer on the media and submit to the Electronic Clearing House (ECH) 2 to 7 days before the value date(effective date). The ECH will process the information with reports one day before the value date for settlement among the member banks and also for the destination bank to prepare debit/credit information to post to the accounts on the value date. The fund will then be available to the customer.Media clearing enables credit and preauthorized debit transfer from the customers or companies. Credit transfer is a fund transfer order from one account to another account at different bank, while preauthorized debit transfer is a fund transfer order from one account to another which requires prior payment agreement.

Why do we need Media Clearing?
1. A company wishes to make a ”One to many”point of payment, such as salaries and dividends.
2. “Many to one”point of payment, such as utility payment.
3. As an alternative way for cheque, which concerns a long processing time and is not an efficient mean for interbank payment.

SWIFT infrastructureThe operating centers consist of 3 types of processing
components; 1. REGINAL PROCESSORS are the outer layer of processing.
They control the traffic flow to and from the access points, they forward messages into the inner layer of co-called slice processors.
2. SLICE PROCESSOR make up the core store-and-forward infrastructure. They also create copies of messages (for audit purpose) and generate confirmations of message reception to the sender.
3. SYSTEM CONTROL PROCESSORS manage the entire system: they monitor the performance, administer the network, and support maintenance tasks.

THE SECURITY OF SWIFT NETWORK1. PRIVATE NETWORK: SWIFT is a private network not the public
Internet.2. MESSAGE VALIDATION: message are checked for compliance with
the syntactical rules and message formats.3. MESSAGE SEQUENCE CHECKING: all SWIFT messages are
assigned unique sequence numbers when entering and exiting the system. These numbers are verified during sending and reception and those that do not follow the expected sequence are rejected.
4. MESSAGE INTEGRITY : when a message is input to the SWIFT network, a Message Authentication Code is created, based on the message content.
5. STRONG LOG-IN AUTHENTICATION: this is based on smart cards and the exchange of electronic authentication keys
6. DATA ENCRYTION: data is encrypted through the network from access point to access point, and to user’s interface device.

Media clearing is the interbank funds transfer system for pre-authorized retail debit/credit transfer having large volume and a regular recurring period. The system uses electronic means such as magnetic tapes and diskettes. The fund processed through this system is available to customers as soon as the paying bank and the receiving bank have settled their payment on the due date.
