The study's goal was to see whether a one - way text messaging machine using RFID will be effective to the students, teachers, and parents/guardians. The study has taken advantage of the school’s usage of RFID to record the attendance. The same RFIDs are to be used to register into the Electronic Cartero Machine (ECM). The researchers built a system where students can message their parents/guardians their concerns by tapping the students registered RFID using the Raspberry Pi as a controller to show the GUI (Graphical User Interface) of the system. The main program is custom made using Java SE (Standard Edition) and Swing. There are 20 respondents to the survey, consisting of the students, teachers, parents/guardians, and administrative staffs to evaluate the appearance, maintainability, ease in usage and accuracy. The survey uses general acceptability indicators to describe the mean of the outcome. From the results of the survey, the appearance mean is 4.25 which suggests that the design of the ECM, especially the GUI is clear and identifiable, the maintainability mean is 4.7 which indicates that it can easily be maintained. Ease in usage is 4.9 which means that it can send the text messages to the proper recipients. The overall mean is 4.5675. It scored "Excellent" on the general acceptability indicators. Furthermore, the researchers discovered that the ECM is similar with the regular cellular phones in terms of sending time. Also, the number of characters being sent affects the sending time of the ECM.
