2.1.    E-Commerce
E-Commerce is a type of industry where buying and selling of products or services is conducted over electronic system such as the internet and other computer networks.
 On the Transaction, E-Commerce have a Many More  Implementation. An e-commerce payment system facilitates the acceptance of electronic payment for online transactions, is not different with E-Commerce.

2.2.    E-Payment
E-Payment is a subset of an e-commerce transaction to include electronic payment for buying and selling goods or services offered through the Internet. Generally think of electronic payments as referring to online transactions on the internet, there are actually many forms of electronic payments.
As technology developing, the range of devices and processes to transact electronically continues to increase while the percentage of cash and check transactions continues to decrease. Based on Survey American.Edu, In the US, for example, checks have declined from 85% of non-cash payments in 1979 to 59% in 2002, and electronic payments have grown to 41%. The Internet has the potential to become the most active trade intermediary within a decade.
 Also, Internet shopping may revolutionize retailing by allowing consumers to sit in their homes and buy an enormous variety of products and services from all over the worlds. Many businesses and consumers are still wary of conducting extensive business electronically. However, almost everyone will use the form of E-Commerce in near future.  

2.2.1   E-Payment System
Based on Wikipedia, The payment system is an operational network-governed by laws, rules and standards - that links bank accounts and provides the functionality for monetary exchange using bank deposits.The payment system is the infrastructure (consisting of institutions, instruments, rules, procedures, standards,and technical means) established to effect the transfer of monetary value between parties discharging mutual obligations. Its technical efficiency determines the efficiency with which transaction money is used in the economy, and risk associated with its use.[1]
E-Payment System Can make sure to user with E-Payment System Security. This is Scheme Protection Who Work on Online payment System.   E-Payment System Security
E-payment System Have a many type to secure Online Payment On the Internet. This is Security Sockets Layer or may be can be called “SSL”, Transaction Layer Security protocol or maybe can be called “TLS”, Secure Electronic Transaction or may be  can be Called “SET”.  Secure Sockets Layer (SSL)
Secure Sockets Layer, more commonly known as SSL, is a protocol that is used to maintain client and server authentication. A site is easily identified as using SSL if it has the small yellow padlock at the bottom of the browser.
In SSL, communication between the server and the client is encrypted using their certificates. This encryption creates virtual information that is not hackable by others.  The steps of how SSL works is shown in the following diagram:

The purpose of SSL is to provide a means to allow secure communication between two parties. However, one party must have a certificate trusted by the other in order to help prevent man in the middle attacks. SSL also supports authentication, encryption and key exchange.
SSL uses a handshake protocol. Suppose a client wants to make a purchase from a website server, but this server does not know anything about the client.
The first step is for the client to send a message to the server. After the server receives the message, it acknowledges it by sending the client a message in return. The server also sends the client its certificate and asks for the client’s certificate. The client sends its certificate, a client key exchange message, and a certificate verification message. Both the client and server send change cipher spec messages and then send finished messages to end the handshake  Transaction Layer Security (TSL)
The Transaction Layer Security protocol, commonly known as TLS, is based on SSL and will soon become its successor. TLS has some changes in its MAC, has clearer and more precise specifications, cleaner handling because of not having a client certificate, and more flexibility.  Secure Electronic Transaction (SET)
Secure Electronic Transaction, SET, provides a way for the client’s credit card number to be sent to authorizing banks. However, there was not enough market acceptance of SET to make it commonplace.

2.2.2   Type Of E-Payment
E-Payment have more types, it’s so make online payment so easily. Customer can choose one way to transaction on online payment. Customer can transaction with Card, Internet, Mobile Payment,  Financial Service Kiosks, Television Set-Top Boxes and Satellite Receiver, Biometric Payments, Electronic Payments Networks, Person-to-Person (P2P) Payments.       Cards

Credit cards, debit cards and prepaid cards currently represent the most common form of electronic payments. For all 3 types of cards the consumer or the business most often uses a plastic card, commonly with a magnetic stripe. The cardholder gives his or her card or card number to a merchant who swipes the card through a terminal or enters the data to a PC. The terminal transmits data to his or her bank, the acquirer. The acquirer transmits the data through a card association to the card issuer who makes a decision on the transaction and relays it back to the merchant, who gives goods or services to the cardholder. Funds flow later for settlement with credit cards and are debited immediately for debit or pre-paid cards.
Along with magnetic stripe cards, smart cards are and will increasingly be used for payments. Smart cards are at present overwhelmingly plastic credit cards with an embedded computer chip. Until recently, many smart cards operated using proprietary rather than common standards. A standard set of specifications, EMV, has been developed and is being used increasingly so that the chips on smart cards are interoperable. Korea and Japan are among the most advanced countries in Asia for smart card payments, with Malaysia catching up fast due to government mandates for banks to issue smart cards. Most credit and debit cards are expected to be issued or reissued as smart cards by 2008 or earlier.
Over time, the chip for payment can be expected to move onto other devices. A “smart card” might then become the computer chip in a phone, PDA or other device that can perform the same function as chip in a plastic card, eliminating the need for the actual plastic card. Smart cards could thus evolve into “smart phones”, “smart PDAs” or other “smart” devices.       Internet
Online payments involve the customer transferring money or making a purchase online via the internet. Consumers and businesses can transfer money to third parties from the bank or other account, and hey can also use credit, debit and prepaid cards to make purchases online.
Current estimates are that over 80% of payments for online purchases are made using a credit card or debit card. At present, most online transactions involve payment with a credit card. While other forms of payment such as direct debits to accounts or pre-paid accounts and cards are increasing, they currently represent a less developed transaction methodology.       Mobile Payments
Mobile phones are currently used for a limited number of electronic transactions. However, the percentage seems likely to increase as mobile phone manufacturers enable the chip and software in the phone for easier electronic commerce. 
Consumers can use their mobile phone to pay for transactions in several ways. Consumers may send an SMS message, transmit a PIN number, use WAP to make online payments, or perform other segments of their transaction with the phone. As phones develop further, consumers are likely to be able to use infrared, Bluetooth and other means more frequently to transmit full account data in order to make payments securely and easily from their phone.
 Additionally, merchants can obtain an authorization for a credit or debit card transaction by attaching a device to their mobile phone. A consortium in the US also recently announced PowerSwipe, for example, which physically connects to a Nextel phone, weighs 3.1 ounces, and incorporates a magnetic stripe reader, infrared printing port, and pass-through connector for charging the handset battery.       Financial Service Kiosks
Companies and service providers in several countries, including Singapore and the US, have set up kiosks to enable financial and non-financial transactions. These kiosks are fixed stations with phone connections where the customer usually uses a keyboard and television-like screen to transaction or to access information.
At AXS stations in Singapore, for example, consumers can make electronic bill payments, send email or SMS message and make phone calls. Kiosks in the United States enable the customer to send money via wire transfers, cash checks, make purchases using cash, and make phone calls.
Located at convenient public locations such as bus or subway stations, convenience stores or shopping malls, these kiosks enable electronic payments by individuals who may not have regular access to the internet or mobile phones.       Television Set-Top Boxes and Satellite Receiver
Specialized boxes attached to a television can also be used for payments in some locations. The set-top box attaches to the television and a keyboard or other device, and customers can make purchases by viewing items on the television. Payment is made electronically using a credit card or other account. While usage is presently low, it could grow substantially in countries with a strong cable or satellite television network.       Biometric Payments
Electronic payments using biometrics are still largely in their infancy. Trials are underway in the United States, Australia and a limited number of other countries.Most biometric payments involve using fingerprints as the identification and access tool, though companies like Visa International are piloting voice recognition technology and retina scans are also under consideration. Essentially, a biometric identifier such as a fingerprint or voice could replace the plastic card and more securely identifies the person undertaking the transaction. The electronic payment is still charged to a credit card or other account, with the biometric identifier replacing the card, check or other transaction mechanism.       Electronic Payments Networks
Various countries have electronic payments networks that consumer can use to make payments electronically. ACH (Automated Clearing House) in the US, domestic EFTPOS networks in Australia and Singapore, and other networks enable electronic payments between businesses and between individuals. The consumer can go online, to a financial service kiosk or use other front-end devices to access their account and make payments to businesses or other individuals.       Person-to-Person (P2P) Payments
P2P payments enable one individual to pay another using an account, a prepaid card or another mechanism that stores value. PayPal in the US, which was recently purchased by Ebay, is one of the most frequently used P2P mechanisms. The Tower Group estimates that the volume of P2P payments will grow from 105 million transactions in 2002 to 1.4 billion transactions by 2005. P2P payments can be made through a variety of means, including services like PayPal, transfers using card readers, or other. In the future other devices, such as mobile phones or PDAs, could also be used to enable P2P electronic payments.


3.1       Definition PayPal
PayPal is a Web-based application for the secure transfer of funds between member accounts. It doesn't cost the user anything to join PayPal or to send money through the service, but there is a fee structure in place for those members who wish to receive money.

With multiple guarantees in place, buyers and sellers entrust paypal with their credit card and bank information. Paypal keeps their private customer information secret. Then while "blinded" from the other party's confidential information, strangers safely send money to each other through paypal and email.
Escrow is a service that provides a means of security in the handling of important property, funds, and documents. An escrow holder works with the Buyers, Sellers, Lenders and Borrowers ("the principals") involved in a transaction to assure funds and documents change hands at the appropriate point in time, after preset conditions have been met.

3.9  Problem With Paypal
Though paypal does have millions of seemingly satisfied customers, not all users have had such a pleasant experience. In fact, so many people have felt slighted by paypal that entire Web sites exist to discuss problems about paypal and mock its business practices. The most prominent is paypal Sucks. The biggest criticism of paypal is that it acts like a bank, but it isn't regulated like one.
This means that paypal offers none of the protection that real banks offer, and it isn't required to maintain any of the security, customer service or dispute resolution services that banks provide. At the same time, paypal holds large amounts of their customers money, makes millions of financial transactions and even offers credit and debit cards. So why isn't it considered a bank? In 2002, the Federal Deposit Insurance Corporation (FDIC) declared that because paypal didn't meet the federal definition of an entity accepting deposits as a bank, hold any physical money or have a bank charter, it was not a bank. In other words, paypal isn't a bank because it doesn't call itself a bank.
As a result, most states license paypal as a "money service." One of the most common problems encountered by paypal users is the sudden and inexplicable freezing of their accounts. If your paypal account is frozen, you can't add or withdraw any funds from your account, and you're required to go through a long, complicated process to verify your identity. Some users claim that paypal has simply seized their funds and never returned them. Other complaints against paypal include rude customer service representatives, a long and confusing User Agreement and loose hiring practices that may have led to account fraud.
