The IoT that is described in this assessment is about Radio Frequency Identification Technology. RFID are used to track items and identify the items (Hutabarat et al., 2016). In this modern world that includes technology to a great extend, RFID is an excellent technology for identification. The features of RFID are they are very fast in identifying many numbers of tags at a time and are has a capability of wireless reading from several meters. The latest IoT technology among all is the Identification with Radio Frequency technology. If an object is shown digitally, it is much easier to control the object from distant places with higher capability. A broad area of Automatic Identification System (Auto-ID) is the RFID system.
The project that is chosen to explain RFID system in this assessment is laundry management (Chung, 2014). The RFID technology helps to improve the efficiency and effectiveness in managing the laundry and also simplify the operations. Tracking and maintaining a laundry manually is very difficult. To obtain a detail record of all the things, it requires a demanding labour to count record and separate the data and inserting them manually in the computer (Gan, Aw & Sheng, 2016). Experienced laundry management is needed for productive laundry management and profitable cost. An Auto-ID RFID technology is useful for adding data to the stock systems. The effort and time for shipping, receiving and shipping the laundry are managed by the RFID technology automatically (Celikkan & Kurtel, 2017). This provides accountability and control in laundry circulation process. In RFID, the status, last recorded time, information of the material, conditions of washing and number of washing cycles that are left are recorded in the system. The basic infrastructure necessary for this type of practical application includes readers and tags, as well as RFID management software, all designed to work together seamlessly (Gordon et al., 2016).
Solution with features
To overcome the process of laundry management RFID modular system is used. The processes that are used in managing the laundry are-
Expedition from the laundry- Clothes are packed and selected accordingly ready to send to the destination and delivery is prepared.
Move the clean items to the destination- Delivery of the items are done to the destination from where they were bought.
Expedition in the destination- Expedition of clothes is done in the destination.
Users- The clean clothes are kept in the proper place and the numbers of newly added clothes are recorded.
Collection service- In collection service, the dirty clothes are again collected in the centralized point and after all the collections are completed, they are accumulately taken to the laundry again.
Move the items back to laundry- The dirty items are collected and move to the laundry for washing, drying and ironing.
Receiving of items- The items are collected and recorded the number of items that are to be cleaned and washed.
Washing, drying and ironing- The items are finally washed, cleaned and ironed with proper care. If repair is needed then the repairmen is done.

The main goal of the project is to realize a SW module that is complex for acquiring data from the readers, providing data for evaluation, filtering, unifying or storing the data in the database by the use of a database server. For unifying and filtering purposes, IoT middleware controls process of reading to all the connected readers and advance raw data collected from the antennas that consists information only regarding the tags in communication area of the antenna and some readers add RSSI information. Data collected are processed, filtered and analyzed for certaining the direction of the passage (Jones & Chung, 2016). The information is shipped to a higher system in single report iteration. The lowest level of the SW module is the communication layer which gives a several protocols of communication according to demanded protocols by distinct readers from distinct manufacturers. Other communication rules are added by the developers and this layer of communication is made universal. Mainly two protocols are implemented. First one is the standardized Low Level Reader Protocol (LLRP) and the second is the proprietary protocol for particular manufacturer. The LLRP supports a larger part of high standard RFID readers. This LLRP protocol gives a control to air protocol and also arrange the control of air protocol of RFID operating timing. The data are processed in LLRP from single RFID tag in EPC (Electronic Product Code) form and configuration of reader.
Pros of using this RFID laundry Management Technology
The advantage of using the RFID technology is the way to use LLRP reader with the help of different manufactures and creates a tenderized interface. The advantages are as follows-
Cons of using this RFID laundry Management Technology
This assessment sheds a light on the importance of IoT in this modern era. Based on IoT, details of RFID technology is described briefly. The RFID technology used in the project describes a laundry management. This paper illustrates the use of RFID technology to improve and simplify the operations if the laundry management. RFID reader is a wireless technology which makes the technology so much useful. RFID also lessens the cost of software.
