Working of the system
This system is made up of 3 parts

(1) Data Collection Devices:
By using fixed and movable corded barcode scanners, time and attendance data can be captured with an ID card that has the employee number in a barcode. A fixed scanner is like a time clock, so the device itself can be programmed to update the time and attendance database appropriately.

To capture detailed operation data, the employee will use a barcode scanner attached with a cord to a PC or other computer running the time and attendance software. The software sequences the input data and updates the time and attendance database appropriately.

(2) Data Collection and Storage Computers:
When the employee scans a barcode, the data of the employees is transferred to a PC running the time and attendance software. Normally, the individual PC’s will be attached to a computer network. The data updates to a database stored on either a company server or a shared file area on a specific computer.

(3) Barcode Time and Attendance Software:
Time and Attendance software is the most important thing in a barcode Time and Attendance system. The success of the system depends on selecting this software which improves the rate of return. Most manufacturers offer free demo programs to evaluate.

With the combination of all the above systems, the barcode time and attendance software is applied to give maximum output.

Employee cards are given to the employees containing unique barcode number. The data like employee name and other professional details may be encoded in the barcode. So each employee will have a unique barcode number. Symbol barcode can be used for this purpose. These are printed by a specific barcode printer. Many companies use Zebra printers for creating barcodes for time and attendance systems. Employee cards are scanned by barcode scanners which record the time in and time out of an employee. A specific software used helps in storing and managing these data for calculating payrolls.

Let us know why barcode time and attendance system is essential.

• Manual systems for managing payroll activities include high labor work. It may also be prone to human errors. It also takes lot of time and effort for storage and management of manual time and attendance systems. In order to avoid these issues, one can use barcodes in time and attendance systems.
• When manual time and attendance systems are used, employees may enter wrong details of their time in and time out. It thus may include frauds and misuse. So it is necessary to apply barcodes in time and attendance systems.
• Certain employees involved in checking payroll issues feel bored and laborious to do it. In the process, they may make some mistakes. They may not report the details to their supervisors in time. The barcode system should therefore be used to reduce their time and effort.
• It must be implemented to eliminate payroll disputes with employees.
• In order to reduce the time required for payroll auditing tasks, it is necessary to follow barcode time and attendance systems.

Because of these reasons, many companies prefer to use barcode time and attendance tracking systems which improves efficiency of payroll activities.

A barcode system consists of four components including barcode labels, barcode scanners, barcode printers and a database. Barcode labels are the tags that contain the data of barcodes in various symbologies. Barcode scanner is the device that is used to read it. Barcode readers are of various types. Symbol barcode scanner, HP Laser barcode scanner and others are mostly used for reading data on barcodes. The labels are printed by means of a barcode printer. The data read by barcode readers is stored in a database. The database consists of the information of inventory.

It is necessary to ensure quality control in businesses that handle transactions including consumer goods. Inventory information of a product in a retail store includes the amount of quantity, description of the product, and the code number. Inventory management by barcode systems has many advantages. Manual checking which consumes time and errors can be avoided by application of barcodes. Barcode inventory systems can be applicable in storing patient records in healthcare industries. Patient visit, dosage of drug administration, any allergic responses, and other related information can be tracked by barcodes using a patient identification card with barcodes. When a patient visits a hospital, all the details can be known by checking the identification card which saves a lot of time.

Barcode inventory control system can also be used in locating items of order list of a warehouse. It also helps in encoding shipping information such as tracking numbers and delivery addresses. Location and analyzing inventory information can be made simple by using barcode inventory control system in real-time. With advances in the inventory management of various products, manufacturers of barocde components are facing high competition. Symbol scanners, Zebra Printers and others are some of the products of prominent manufacturers.

Compliance labeling has been becoming prominent in many industries ranging from automotive parts to electronic manufacturers. The main aim in compliance labeling is creating more efficient and useable barcode labels within a given industry or market sector.

All the information encoded, symbologies used, layout of the label, and additional text information and graphic required should be made properly. If the label does not meet the specifications mentioned then the customer may even level a penalty. Good label printers should be used for printing labels that meet size, construction and information requirements. These printers allow one to be assured that the compliance labeling needs have been properly met. This may result in reducing the expenses associated with failed labeling.

An on-line verifier system is the one which checks each barcode when it is printed. The printing is interrupted when an out of specification symbol is detected. This verifier system helps in the quality control of checking the labels. When less stringent requirements are there for a label, then a statistical sampling with a handheld verifier is sufficient.

When an industry decides to move towards compliance labeling, no hesitation should be there for finding a reliable professional source of labels. Different label printers are available that can be used for printing labels of any industry standards.

There is a necessity to decode the information to be read from the barcode. The reading of the barcode label is done by a barcode scanner. A multitude of barcode scanners such as Symbol barcode scanner, HP Laser barcode scanner and many are offered by the market. Each model has its own specifications, uses and benefits. Let us now discuss about the scanners that are generally used in some modern businesses.

A document scanner is used by the organizations that have a chain of computers. In a storehouse hundreds of different types of products and materials have to be scanned and tracked. These are to be scanned many times as and when they go in and out of the storehouses. A modern barcode scanner should be used by such storehouses.

The selection of barcode scanner is important. It is also based on the type of business. The laser scanners are one of the type of scanners that work with a thin red laser that is released from the device. A laser scanner can read a barcode from a greater distance. Hence these are used mostly in industrial areas. Where as, the LED scanners are used in small retail stores.

Throughout the retail supply chain processes from factories to outlets the retail barcode scanners are used. Two types of retail barcode scanners are available. These include in-counter and on-counter barcode scanners. When there is high sales volume in the retail outlets, the in-counter barcode scanners are used. In stores that have limited space on the counter, the on-counter barcode scanners are used.

Linear image barcode scanners are also called as CCD scanners. These are full array imagers. Less maintenance is required by these scanners as no moving parts are present. Hence they are more durable compared to other types. Damaged and poorly printed barcodes, and the barcodes that are under a plastic film or covering can also be read by CCD scanners. They have compact size and are light in weight. Hence they can be preferred to be used ideally in offices.
