Reader Briefing

Technologists urge Constitutional Court to call them as witnesses regarding alleged ballot tracking via QR codes, presenting evidence that such codes and barcodes could link votes to individuals.

  • •Dr. Thanarat Sukchotirat (Dr. Robbin) and technologist Thanarat Guawattuanapan submitted additional evidence to the Ombudsman concerning QR and barcodes on ballots.
  • •They claim these codes can identify voters, potentially violating the secrecy of elections, and wish to present this to the Constitutional Court.
  • •Evidence includes technical data from QR/barcodes and media submissions, demonstrating how votes might be traceable.

Overview

  • •On March 25, 2026, at 11:00 AM, at the Office of the Ombudsman, Mr. Thamtheer Sukchotirat and Mr. Thanarat Guawattuanapan submitted evidence.
  • •The evidence relates to the 2026 election case, where the Ombudsman forwarded an opinion to the Constitutional Court under Article 213 of the Constitution.
  • •The core issue is the belief that barcode and QR code usage on ballots can identify voters, thus violating the secrecy of the vote contrary to the constitution.
