On 21 July 2025, the Bill No. 3904-D-2025 was introduced in the Chamber of Deputies. The Bill aims to amend Article 2 of Law No. 26.637, under the title Bank Security – Modification of Article 2 Incorporating Computer Crimes, Digital Evidence and Chain of Custody. The Bill mandates financial institutions and payment service providers, as defined by the Central Bank of the Argentine Republic (BCRA), to adopt both physical and digital security measures to protect individuals, assets, and sensitive information, including mechanisms for detecting, monitoring, and preventing specified cybercrime offences. The amendment enumerates offences under the Argentine Penal Code, including unauthorised system access, privacy violations, data sabotage, digital fraud, identity theft, use of artificial intelligence for impersonation, and biometric data manipulation, among others. It also requires the judiciary and security forces to comply with updated procedural standards for the collection, preservation, traceability, and judicial validation of digital evidence, in accordance with legal safeguards and the chain of custody principle. The Bill repeals prohibitions on mobile phone use and signal jamming in bank branches and delegates to the BCRA a 60-day timeframe to issue implementing regulations. The Bill was referred to the Committees on Finance (first competence), Interior Security, and Justice in the House of Representatives for further deliberation.
