The Chile Financial Market Commission (CMF) board has postponed the removal of coordinates cards as a user authentication mechanism for payments and electronic transactions until 1 August 2026, and amended the start of mandatory Reinforced Client Authentication (RCA) so both measures take effect on the same date. The change extends the implementation timeline set under General Rule No. 538, which raised client authentication security standards to reduce fraud in electronic transactions. The CMF framed the delay as providing additional time for payment instrument issuers to migrate to more robust authentication methods, particularly for customer segments that make intensive use of printed coordinates cards, while maintaining continuous and uninterrupted access to financial products and keeping clients informed as operational changes are rolled out.
