Bank of Thailand Proposes New Digital Channel Security Standards

Subscribe to Updates

On July 23, 2026, the Bank of Thailand (BOT) released for public comment its draft Notification on Digital Channel Security, which would significantly expand the scope and stringency of Thailand’s existing mobile banking security framework. If finalized in its current form, the draft notification would extend mandatory security requirements to credit card providers and credit providers, cover internet banking in addition to mobile applications, phase out SMS one-time passwords (OTPs) for transaction authentication, and introduce biometric verification requirements for high-value transactions. The public comment period is open through August 24, 2026.

Background

The BOT’s existing Mobile Banking Security Notification, issued in 2024, sets minimum security standards for financial institutions, specialized financial institutions (SFIs), and e-money providers, significantly reducing “money-draining app” fraud. However, fraudsters have since shifted to nonbank providers and internet banking channels, prompting the BOT to propose broader security requirements.

Expanded Scope of Regulated Entities and Channels

The existing Mobile Banking Security Notification covers only financial institutions, SFIs, and e-money providers offering mobile banking services. The draft expands coverage in two key areas: entities and channels. On the entity side, it adds credit card providers and credit providers that offer fund transfers to third parties at other financial service providers or that provide cash withdrawal services to individual retail customers. On the channel side, it broadens coverage to include internet banking in addition to mobile banking.

Strengthened Customer Authentication

The draft introduces enhanced authentication requirements in three areas:

  • Service enrollment and device changes. Providers must implement rigorous identity verification, notify customers of enrollment results through out-of-band communication channels, and adopt risk-mitigation measures such as cooling-off periods and temporary transaction limits.
  • Transaction-level authentication. Providers must use two-factor authentication for fund transfers, cardless ATM withdrawals, and transaction limit increases.
  • Secure authentication factors. Key requirements include the following:
    • “What-you-know” factors must protect against brute-force attacks.
    • “What-you-have” factors must use secure methods such as a registered mobile application with device binding or hard/soft tokens.
    • SMS OTPs must be discontinued for transaction authentication.
    • Biometric factors must use effective antispoofing technology, such as facial scanning, in compliance with the BOT’s guidelines on biometric technology in financial services.

Providers must cease sending SMS messages and emails containing embedded links and must establish incident response processes for counterfeit applications or websites.

Mobile Application Security Controls

Providers must ensure application integrity and block remote-access applications. Facial comparison with antispoofing technology is required for transfers exceeding THB 50,000 (approx. USD 1,490) per transaction or THB 200,000 (approx. USD 5,960) per day.

Next Steps

Affected financial service providers should assess their current systems against the draft requirements and consider submitting comments to the BOT by August 24, 2026.

Thailand’s telecommunications regulator has introduced a range of new compliance obligations for telecom licensees aimed at preventing and suppressing technology crime. On May 15, 2026, the National Broadcasting and Telecommunications Commission (NBTC) published in the Government Gazette Notification on Measures for Prevention and Suppression of Technology Crime No. 2, which amends the original NBTC notification dated August 24, 2025. The amendment derives its authority from the Emergency Decree on Measures for Prevention and Suppression of Technology Crime B.E. 2566 (2023), as amended in 2025, and took effect on May 16, 2026. SIM Card Registration Cap for Non-Thai Nationals Persons without Thai nationality are now limited to a maximum of three SIM cards per person per service provider. Identity verification must be done primarily via passport. For those without a passport, acceptable alternatives include travel documents or certificates of identity issued by foreign governments, accompanied by additional Thai government-issued documents, as well as pink ID cards (for persons without Thai nationality) and white ID cards (for persons without registration status). Registration must be done in person at a branch or authorized dealer. Service providers must develop their identity verification systems and obtain NBTC approval before deployment. SIM Activation Deadline and SIM Box Prohibition Both Thai and non-Thai service users must activate their registered SIM within 60 days of registration. If they fail to do so, they must re-verify their identity in person before activation, confirming they are the same person who originally registered. Service providers must prohibit SIM box and gateway devices capable of supporting four or more SIMs from connecting to their mobile networks unless the device has received a license under the Radio Communications Act. Blacklist Enforcement Service providers must refuse registration of additional mobile numbers for persons listed on a technology crime-related database maintained by the Royal

Thailand has introduced new requirements for online social media platforms to verify the identity of paying advertisers before publishing their advertisements. On May 5, 2026, the Electronic Transactions Commission published the Notification on Measures for Prevention of Technology Crime for Online Social Media (No. 2) in the Government Gazette. The notification, which aims to prevent technology crimes such as fraud and scams, takes effect 180 days after publication (i.e., on November 1, 2026). Mandatory Advertiser Identity Verification Online social media service providers must verify the identity of every advertiser before publishing an advertisement. Verification remains valid for up to one year from the most recent verification date. The notification requires social media providers to use either of the following methods when verifying advertisers: Document-based verification: Examine government-issued identity documents (e.g., national ID, passport, or juristic person registration certificate), cross-check the connection between the advertiser and the identity documents (e.g., facial comparison with photo ID), and ensure that the identity documents are verifiable against reliable sources. Digital identity verification: Use an identity verification system with a level of assurance no lower than that prescribed by the Electronic Transactions Commission. Advertiser Data Collection and Retention Service providers must collect and retain certain data—including name, identification number, and contact details—from the start of the advertising service and for a minimum of 90 days after the end of the advertising service relationship. The same requirements apply where there is a third-party payer, such as an ad agency. Implications for Affected Businesses The notification raises two key areas of concern for affected businesses: Social media platforms must implement know-your-advertiser (KYA) onboarding as described above, including document upload and identity matching processes. The 180-day implementation window requires immediate technical and operational planning. The collection and retention of national ID cards, passport copies, and other personal

Vietnam’s Decree No. 134/2026/ND‑CP, which took effect on 9 April 2026, plays an important role in detailing and implementing Vietnam’s Intellectual Property (IP) Law in the context of rapid digital transformation and the growing application of artificial intelligence (AI). The new decree provides comprehensive guidance on the application of copyright and related‑rights regulations, addressing key issues such as authorship, ownership, statutory exceptions and limitations, registration procedures, and enforcement mechanisms. Through these measures, Decree 134 seeks to achieve an appropriate balance between safeguarding the legitimate interests of rightsholders and fostering innovation, research, and technological advancement, thereby strengthening the state’s framework for the effective management, protection, and exploitation of intellectual property in the digital and AI‑driven environment. Some notable aspects of Decree 134 are discussed below. Copyright for AI-Created Works Decree 134 provides important guidance on the determination of copyright and related rights in works created with the assistance of AI. Article 5a reaffirms the principle that human creativity remains central to copyright protection, clarifying that copyright or related rights arise only where a human makes a substantial and decisive intellectual contribution, exercises effective control over the creative outcome, and assumes responsibility for the content and its legality. At the same time, the provision confirms that AI is regarded solely as a technological tool rather than a rights‑holding subject, thus ensuring consistency with the fundamental concepts of authorship and ownership under the IP Law. By introducing requirements on transparency, proof of human contribution, and compliance with AI‑specific labelling and technical marking obligations, Decree 134 establishes a clear and enforceable legal framework for the responsible use of AI in creative activities. Lawful Use of Copyrighted Texts and Data Article 37a of Decree 134 sets out the specific conditions under which copyrighted texts and data may be lawfully used for scientific research, experimentation,

Vietnam has progressively positioned blockchain as a strategic technology within its broader digital transformation agenda over the past decade. From early policy orientations to more recent legislative developments, the regulatory approach has gradually shifted from high-level recognition to more concrete legal integration. Against this backdrop, a new draft decree regulating activities relating to product and goods identification, authentication, and traceability (the “Draft Decree”) marks a notable turning point. Rather than merely referencing blockchain as a policy priority, the Draft Decree incorporates blockchain directly into a nationwide regulatory system, positioning it as part of the underlying infrastructure for data governance and public administration in relation to the management, verification, and traceability of product-related data. Evolution of Vietnam’s Blockchain Legal Framework: The Draft Decree in Context Vietnam’s blockchain legal framework has developed in several distinct phases. The first phase, beginning around 2019, was characterized by high-level policy recognition in several resolutions of the Party Central Committee. Particularly, blockchain was identified as part of the broader category of digital technologies critical to industrial modernization and participation in the Fourth Industrial Revolution. These resolutions did not regulate blockchain directly, but established its strategic importance at the national level. The second phase (2023 to 2025) saw the introduction of national strategies and technology policies that more explicitly recognized blockchain as a priority technology. Those policies collectively signaled a clear policy commitment to developing blockchain infrastructure and applications. However, these instruments remained largely at a policy-level and did not establish binding regulatory frameworks. The third phase (from 2025) involves the gradual integration of blockchain into sectoral legislation. Laws such as the Law on Digital Technology Industry (2025), the Law on Personal Data Protection (2025), and the Law on Science, Technology, and Innovation (2025) have introduced concepts such as digital assets, crypto assets, and even specific
