Thailand: New Payment Systems Act

Thailand is in the process of reforming laws related to payment systems and services, as well as consolidating several overlapping laws that regulate electronic money businesses, with the National Legislative Assembly approving the new Payment Systems Act in August 2017. The new draft of the bill is awaiting royal assent and is expected to be published in the Government Gazette within this year, becoming effective 180 days after its publication.

Under the current system, a business that wishes to provide a certain type of e-money service is required to apply for two licenses, in accordance with two laws: (1) the Royal Decree Regulating Electronic Payment Services B.E. 2551 (2008); and (2) the Notification of the Ministry of Finance: Business that Requires a Permit according to Section 5 of the Notification of the Revolution Council No. 58 (Electronic Money Card Businesses), dated October 4, 2004. Once the new Payment Systems Act comes into force, it will simplify procedures for business operators by repealing these laws.

Under the new law, different types of electronic payment systems and businesses will be reclassified into three new classifications: (1) important e-payment systems; (2) supervised e-payment systems; and (3) supervised e-payment services. Criteria for supervised e-payment systems and e-payment services will be determined in ensuing subordinate legislation by the Minister of Finance, based on recommendations from the Bank of Thailand (BOT). 

Current business operators will be required to reapply for registrations or licenses if their businesses fall within the category of a supervised e-payment system or a supervised e-payment service. Certain new businesses that fall under either category may be required to apply for registration, rather than applying for a license (e.g., new businesses utilizing new financial technology that are in the process of being tested, or providing services to a limited number of customers which may not significantly impact public interests).

The BOT will be the key regulator of the new Payment Systems Act and will supervise the operation of payment systems and payment services, with the Electronic Transactions Commission supervising information technology security standards. The law grants the BOT the authority to announce rules and regulations relating to: 

  • minimum financial status and performance;
  • business operation standards;
  • good governance;
  • risk management;
  • outsourcing;
  • collection and disclosure of a customer’s personal data;
  • customer protection; and
  • security systems. 

Business operators and their management will be required to submit financial statements, operations reports, accounts, and data relating to the business operations, in any form, with the BOT having the authority to examine business operations, assets, and debts of business operators. In the case of noncompliance, the BOT may order business operators to rectify any associated problems, or it may impose a temporary suspension or cessation order within a specified period. Noncompliant business operators may be subject to administrative fines of up to THB 3 million, and criminal penalties that include imprisonment of up to 10 years and/or fines of up to THB 10 million.

Reformation of the payment systems law in Thailand will result in more streamlined license application and compliance obligations for business operators, as well as the establishment of an effective regulatory framework to support the development of e-payment services and businesses under the government’s “Thailand 4.0” policy.

Thailand published new rules on May 1, 2026, establishing clear procedures for how the Anti-Money Laundering Office (AMLO) handles digital assets seized during criminal and money laundering investigations. Taking effect the following day, the Regulation of the Anti-Money Laundering Board on the Custody and Management of Seized or Frozen Assets (No. 3) B.E. 2569 applies to digital asset businesses, cryptocurrency holders, and anyone subject to asset seizure under Thailand’s anti-money laundering laws. For the first time, authorities now have a detailed roadmap for transferring seized digital property from private or foreign control into secure state custody. Digital asset businesses holding customer assets under investigation must be prepared to comply with these rules compelling repatriation of such assets in enforcement actions. Expanded Definition of Digital Assets The regulation defines digital assets to include not only those covered by Thailand’s existing digital asset business law but also any other property that can be stored using the same methods as digital assets. This broad formulation means the custody rules will apply to emerging blockchain-based assets and tokenized property that may not yet fall within the statutory definition of a digital asset business, giving authorities flexibility as the technology evolves. Mandatory Transfer to Domestic Custody When digital assets are held with service providers outside Thailand, AMLO will first attempt to transfer them to an account the office maintains with a licensed domestic digital asset business operator. If the domestic operator does not support that particular asset, the office will instead move the assets to its own cold wallet (offline, internet-isolated storage system). If neither option is feasible, the seizing official will report the situation to the Anti-Money Laundering Committee for alternative instructions. A similar hierarchy governs assets held in an accused party’s private wallet or by any third party that is not a

On May 8, 2026, the Thai government held a press conference to announce a coordinated, multiagency initiative to strengthen oversight and enforcement over products sold on online platforms. The initiative involves the Office of the Consumer Protection Board, the Thai Industrial Standards Institute, the Electronic Transactions Development Agency, the Thailand Consumers Council, the Consumer Protection Police Division, and major online platform operators. With this appointment, the government has signaled a deliberate shift from a predominantly reactive enforcement framework toward a more proactive regulatory and monitoring approach for online commerce and digital platform services. Legal and Regulatory Reform The government is accelerating a proposed Product Liability Law that would introduce new statutory frameworks for defective or substandard products, along with amendments to food safety and consumer protection legislation. The draft law has already been approved by the cabinet; the Council of State and relevant authorities will further draft the law and subsequently issue it for public hearings prior to enactment. Authorities also plan to expand enforcement measures against noncompliant businesses and distributors. In particular: The implementation of stricter “know your merchant” (KYM) identity verification requirements for online sellers. Expanded mandatory standards and regulatory oversight for high-risk products, such as power banks, electrical appliances, food products, and household goods. Increased monitoring of online product listings, and coordination with platform operators to remove unsafe, counterfeit, misleading, or otherwise noncompliant products. Additional monitoring and enforcement measures targeting online scams and illegal goods distributed through digital platforms, including e-cigarettes, which authorities identified as a growing concern due to increasing online distribution channels and potential health impact on young consumers. Strengthening Consumer Complaint Mechanisms The government announced increased cooperation with the Thailand Consumers Council and other agencies to facilitate complaint handling, market monitoring, and policy recommendations. Enhanced interagency coordination will aim to ensure that consumer

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
