3Online Payment

What is Paying Online?

Paying for something over the Internet

Process

4Benefits

The main benefits:

Convenient Any Place & Any Time

Fast and Easy Prompt Access To CareMate Service

5Payment System

Type of Payment System

1. E-Cash

2. E-Check

3. E-Wallets

4. Micropayment

6E-Cash

Similar to regular cash, e-cash enables transactions between

customers without the need for banks or other third parties.

When used, e-cash is transferred directly and immediately to t

he participating merchants and vending machines.

Electronic cash is a secure and convenient alternative to bills

and coins.

7E-Check

E-check is the result of cooperation among several banks, go

vernment entities, technology companies, and e-commerce

organizations.

The key advantages of e-checks are as follows:

1. Secure and quick settlement of financial obligations

2. Fast check processing

3. Very low transaction cost

8E-Wallet

Electronic wallets being very useful for frequent online shop

pers.

They offer a secure, convenient, and portable tool for onlin

e shopping.

They store personal and financial information such as credit

cards, passwords, PINs, and much more.

9Micropayment

Merchants must pay a fee for each credit-card transaction

that they process; this can become costly when customers

purchase inexpensive items.

Using micro-payment one will be able to pay for one article

from a professional journal, a chapter from a scientific book,

or one song from a CD on the Web.

Secure EPS Infrastructure

Some or all of the following security measures and technologies

directly related to EPSs:

Authentication

Public Key Cryptography

Digital Signatures

Certificate authorities,

SSL

S-HTTP

Secure Electronic Transmission (SET)

11

Authentication

This is the process of verification of the authenticity of a pers

on and/or a transaction.

There are many tools available to confirm the authenticity o

f a user.

For instance, passwords and ID numbers are used to allow a

user to log onto a particular site.

12

Public Key Cryptography

Public key cryptography uses two keys , one public and one

private , to encrypt and decrypt data, respectively.

Cryptography is the process of protecting the integrity and

accuracy of information by encrypting data into an unread

able format, called cipher text.

13

Digital Signature

Rather than a written signature that can be used by an indi

vidual to authenticate the identity of the sender of a messa

ge or of the signer of a document; a digital signature is an e

lectronic one.

14

Certificate

A drivers license is accepted by numerous organizations bo

th public and private as a form of identification due to the l

egitimacy of the issuer, which is a government agency.

Certificate authorities are similar to a notary public, a comm

only trusted third party.

15

Secure Sockets Layer (SSL)

Secure Sockets Layer transmits private documents via the Int

ernet .

SSL uses a cryptographic system that uses two keys to encry

pt data - a public key known to everyone and a private or s

ecret key known only to the recipient of the message.

It operates between the transport and the

application layers in the network stack

and uses both public and private key

cryptography.

16

Secure Hypertext Transfer Protocol

SHTTP is designed to transmit individual messages securely.

SSL and S-HTTP, therefore, can be seen as complementary ra

ther than competing technologies.

17

Secure Electronic Transmission (SET)

The Secure Electronic Transmission protocol imitates the curr

ent structure of the credit card processing system.

SET replaces every phone call or transaction slip of paper wit

h an electronic version.

The SET protocol offers packets of data for all these transacti

ons, and each transaction is signed with a digital signature.
