Abstract
This research discusses the design and build of an Internet of Things (IoT)-based vending machine prototype with a payment method using Radio Frequency Identification (RFID). The system is designed using the ESP32 microcontroller connected to an RFID reader, DC motor, photointerrupter sensor, and RTC as the main controller. The Blynk application is used as a medium for monitoring drink stock and real-time notifications. Test results show that the prototype can perform cashless transactions with RFID automatically, dispense products according to user selection, and display stock data through the Blynk application. The application of RFID and IoT technology in vending machines has proven to improve operational efficiency, reduce cash transaction usage, and provide a more practical transaction experience. This research is expected to be a modern solution for digitally based automatic sales systems in the future.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
