Mexican banks began requiring official identification and biometric data for large cash transactions on July 1 [2].
These measures target high-value movements of currency to curb financial crimes. By implementing stricter verification, the banking sector aims to reduce the anonymity often exploited during illicit financial activities.
The Asociación de Bancos de México (ABM) and its affiliated banks are implementing these controls across branches in Mexico [1]. Under the new rules, any cash deposit or withdrawal that exceeds 140,000 pesos [2] requires the customer to present an official government ID and provide at least one biometric data point, specifically a fingerprint [1].
Bank officials said the initiative is designed to reinforce the prevention of money laundering and fraud in high-amount operations [1]. The requirement ensures that the person conducting the transaction is the verified owner of the funds, or an authorized representative.
This shift toward biometric verification represents a tightening of oversight for physical cash handling. While smaller transactions remain unaffected, the 140,000-peso threshold [2] creates a clear boundary for enhanced security protocols.
Clients visiting bank branches must now be prepared for this additional step during the verification process. The transition to biometric data collection is intended to create a more reliable audit trail for the Mexican financial system [1].

The move by the ABM signals a broader effort by Mexico to align its financial infrastructure with international anti-money laundering (AML) standards. By linking high-value cash movements to immutable biometric markers, the government and financial institutions are reducing the utility of 'straw man' accounts and fraudulent identities, potentially slowing the flow of illicit capital through the formal banking system.
