RFID Implementation.


RFID (Radio Frequency Identifier) is an interesting and booming technology in tracking, monitoring and administration in many industries. These RFID devices automatically transmit radio frequency which has a unique serial number for identification that particular devices uniquely. RFDI technology uses few main components in their architecture to provide complete and comprehensive system. Main components are RFID tag, Tag readers, RFID antennas, RFID controllers, RFID premises servers, and RFID integration servers.

RDIF architecture is shown in below diagram for better comprehension.

Implementation of RFID projects needs to be thoroughly planned and organized due to its nature of complexity, cost and needed expertise knowledge. First of all network administrator should have clearly identify the use case of RFID project. Planning, designing, and implementation of RFID project is based on the use case. Hence, meeting all the requirements of users is a great achievement but very difficult task for the implementer due to compatibility of hardware/software, environmental, budget, and organizational structural issues. When implementing RFID project minimum of below points needs to be adequately addressed.

Project objectives must be clearly defined and understood by the RFID team before hand doing anything. To understand clear objectives you need to identify why the organization is required to have RFID implementation, to serve what purpose. Whether it is trying to comply with some regulations or trying to improve productivity, efficiency or cost reduction in long run for their production environment or warehouse. This identification of reasons and setting objectives based on the facts you collected will help having smooth implementation process.

There should be a proper site survey to analyze the current infrastructure to identify places needs implementation of RFID. Selection of RFID product such as RFID tags, RFID readers, RFID antennas, etc need to be determined by the project team to suit the project budget. This is an area where there are lot of questions been rose. Your budget may not be enough to purchase required hardware devices such as RFID tags, RFID readers, etc with expected quality thus, this may leads to improper operation of devices when integrating, mismatch of your requirement or low quality of service. It is important to point out the disadvantages of having a fixed budget which cannot facilitate the organizational main purpose, thus get your budget approved for correct devices or else proceed with compromised budget, which is not recommended. On the other hand make sure your devices that are going to be purchased are well tested and have met quality and compliance standards in industry. There may be other RFID systems already in place in the organization or different system using radio frequency, in these conditions proper investigation should be carried out to identify the interferences that these existing systems may have on the RFID project you are going to implement.

Next step is to align your project to the organizational processes. Your organization’s business in the main concern, and this RFID implementation should benefit to the organization as a whole and improve the processes without adding burden. Due to new RFID implementation there may be a need to process/procedure realignments, adding new process/procedures, removing redundant processes/procedures, etc, which have to be well analyzed and adjusted to suit the business needs and implementation of RFID project.

Software configuration and integration of RFID devices play an important part in the RFID project. All the devices need to place in appropriate places as decided during the planning stage and configure software to connect all RFID devices and meet organization expectations. It is acceptable to start with the default configurations for general purposes applications. But fine tuning to get maximum accuracy and high performance needs well trained professional knowledge.

When all the things are in place monitor how interdependent components behave in the system. For instance all processes, equipments, software, and human aspect of the entire system needs to operate in collaboration to produce better result. Monitor all aspects to identify places where it needs adjustments to smooth the operation of RFID system to improve performance and efficiency.

One main aspect needs to address above all stages is education, awareness and training for users and manage the positive/negative resistance of users. People might have a misunderstanding of that implementation of RFID system will eliminate the human resources in the process which may results in loss of employment. If this situation cannot be managed diplomatically, this might result in a project failure with large amount of financial, and human resources wastage.

Applying RFID in real time or in line process just to serve the purpose of customer compliance is not going to give you a cost effective solution. But if the customer compliance is going to make huge difference in the market place than when it is not compliance, then the implementation is definitely going to give financial advantage. If the customer compliance is not going to add ad impact to your market place, then these are going to add some additional cost to the production due to its implementation of RFID tags. Thus, if the organization can find another a place where they can improve a production process, streamline warehouse operation, or improve logistic services, etc with the implementation of RFID system along with complying customer requirement, then the organization is reaping the true benefit of implementing RFID system.
