Wireless credit card machines are at the forefront of credit card processing technology. Many have built in pin pads and thermal printers to make them a complete mobile transaction solution. They are lightweight, very portable and are easy to use.
• A wireless credit card machine comes with advanced technology but also with a much higher price tag when compared to standard POS terminals. The starting price on a wireless credit card machine is around $850.00 for full featured terminals and can go up from there.
• Wireless credit card machines are most often used in mobile and trade show businesses, but are becoming more common in upscale restaurants, taxi, limo, and delivery services.
• The comstar charge anywhere terminal has a much lower price, but does not include an attached printer. One of the benefits of wireless terminals is a feature called store and forward. This service allows cards to be processed when no cellular service is available, by storing the card and transaction information obtained in the swiping of the credit card. The merchant later completes the transaction when service is available. By using store and forward, a merchant will never have to turn down a sale.
• Most wireless terminals have built in pin pads, and are also able to operate with electronic check acceptance services. Due to federal regulations, both debit and electronic checks must be processed through a land line connection and cannot be processed wireless. This is due to the added security that is required when transactions involve a customer’s bank account.
How Wireless Network works
Wireless credit card machines operate on wireless networks, and thus require additional wireless fee's for the cellular service. A wireless credit card machine can be used with a normal phone line if cellular service is not available within a particular area, or can be set up with a store and forward system when no telecommunication method is available at all.
Important Wireless Network Information
1. Mobitex Wireless Processing Network
It uses a satellite network, and operates similar to a cellular phone. This network is the standard for wireless processing. The mobitex network is run by Velocita Wireless. This is not the standard cellular phone network, but is designed specifically for business and processing uses.
2. CDPD Wireless Processing Network
It is similar to but pre-dates the Motient network is called CDPD. Machines that use the CDPD system will soon be useless on the wireless processing network because the CDPD system is being abandoned. It is important when purchasing a wireless terminal to ensure that the machine does not use the CDPD wireless network but uses the Motient or CDMA networks.
3. Wireless Network
Wireless Network is very new for processing is the standard GSM and CDMA cellular phone networks. The GSM network is used by Cingular and T-Mobile. The CDMA network is used by Verizon and Sprint Wireless. These systems are the networks that most cellular phones operate on, allowing for a very large coverage area and reliable service. The coverage area is substantially larger than the Motient Network.

Definition & Basic Terms of Computer
A computer is a machine for manipulating data according to a list of instructions known as a program.
1. Computer is electronic device which is use in storage and processing information. Computer is a very fast working
2. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations.
3. A computer that stores retrieve and process data from backend. Give the result on your screen. It is very fast device. Calculation is very fast.
Computer:
Having the characteristics of simulating computer-generated output, such as printout, and illuminated displays.
1. A device that accepts data, processes the data in accordance with a stored program, generates results, and usually consists of input, output, storage, arithmetic, logic, and control units.
2. A functional unit that can perform substantial computation, including numerous arithmetic operations or logic operations, without human intervention during a run.
Data:
Representation of facts, concepts, or instructions in a formalized manner suitable
for communication, interpretation, or processing by humans or by automatic means. Any representations such as characters or analog quantities to which meaning is or might be assigned.
Program:
1. A plan or routine for solving a problem on a computer.
2. A sequence of instructions used by a computer to do a particular job or solve a given
problem. To 3.To design, write, and test programs.
Input output:
Input/output, or I/O, is the collection of interfaces that different functional units of an information processing system use to communicate with each other, or the signals sent through those interfaces. Inputs are the signals received by the unit, and outputs are the signals sent from it. The term can also be used as part of an action; to "do I/O" is to perform an input or output operation. I/O devices are used by a person (or other system) to communicate with a computer. For instance, keyboards and mice are considered input devices of a computer and monitors and printers are considered output devices of a computer. Typical devices for communication between computers are for both input and output, such as modems and network cards.
Computer Software:
The term "software" was first used in this sense by John W. Tukey in 1957. In computer science and software engineering, computer software is all computer programs. The concept of reading different sequences of instructions into the memory of a device to control computations was invented by Charles Babbage as part of his difference engine. The theory that is the basis for most modern software was first proposed by Alan Turing in his 1935 essay Computable numbers with an application to the
Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware). This includes application software such as a word processor, which enables a user to perform a task, and system software such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software.
Computer Hardware:
Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data, which are "soft" in the sense that they are readily created, modified or erased on the computer. Firmware is a special type of software that rarely, if ever, needs to be changed and so is stored on hardware devices such as read-only memory (ROM) where it is not readily changed.

Basic Knowledge for Buying Computer
To buy a good computer you need to decide what the computer will be used for. Common tasks include web browsing, office work, digital photography editing, watching movies, computer games, editing video, CD or DVD burning and other tasks.
Once you know what your computer will be used for you it will simplify the choice of different components, for example there is not point in buying very expensive LCD screen that will be great for gaming if it will be only used for editing office documents.
Computing has advanced rapidly during the last few years. With new technologies and improvements that were introduced it might be a little tricky to choose the best computer for your needs.
You will have many factors to consider when deciding on which computer equipment to buy. This guide will help you compare computer equipment features, and help you to examine and sift through many of the basic items before you buy a new computer. Components
A typical computer consists from the following components:
• Mother board
• Processor
• Memory
• Storage devices
• Display
Mother board
Motherboard is the main board of the computer, almost every computer part connects to it. The motherboard has slots for different components.
• In Processor socket each socket is designed for a specific type of processor so not every processor will fit every motherboard. This means that AMD processor will not work with Intel motherboard and vice versa.
• Memory socket is for the memory.
• Graphic card slot is a slot for the graphic card.
• PCI slot is used for add on cards such as modems, network adaptors, TV capturing cards, USB or Fire wire cards. There may be additional slot types on the motherboard but they are for legacy cards.
Processor
Processor is a chip that performs all the calculations in the computer. The processor operating frequency is measured in Hz. The processors are manufactured mainly by Intel and AMD. The processor connects to a socket on the motherboard. Each processor range is designed for a specific socket types. Since Intel and AMD use different socket types mother boards designed for Intel processors are not compatible with AMD and vice versa.
Memory
The operating memory is used by software for loading data for faster access. The memory size is measured in MB. Some programs require a certain amount of memory size for optimal results. The memory operates at different frequencies measured in HZ the faster the frequency the faster the performance. Each memory type is designed for a specific motherboard chipset. To pick a suitable memory for the motherboard check the motherboard‘s manufacturer specifications for the memory.
Storage Devices
Most hard drives in today market will provide more than enough storage. The basic computer equipment comes with 40GB or larger, which is plenty for most tasks. But for working with graphics, video, music, or large databases 80GB should be the minimum.
Display
There are two types of computer displays CRT and LCD.LCD monitors are more expensive but take less space than CRT monitors.
• CRT are based on the old cathode ray tube technology, they are cheaper than LCD monitors but take more space on the desktop.
• LCD stands for Liquid Crystal Display. The LCD displays are thin and take less space than CRT monitor. However some LCD monitors have slow response time that may lead to “ghost” artifacts during games or video files display.
Warranty and Tech Support
A one-year warranty on most computer equipment is plenty, because most problems seem to happen in the first year. If you want you can get an extended two to three year warranty for around $150 to $200.
