Proximity Cards Are a Liability: The Urgent Need to Modernize Access Control

In a recent Security Magazine byline, rf IDEAS President David Cottingham outlines the growing risks of legacy authentication methods and the urgent need for credential modernization. With over 3,000 data compromise incidents affecting 1.3 billion individuals in 2024 alone, the stakes have never been higher.

Cottingham highlights how proximity cards—still widely used across industries—transmit fixed identifiers without encryption, making them easy targets for cloning and unauthorized access. He explains how attackers can exploit these vulnerabilities to escalate from physical entry to digital breaches in under an hour.

The article also explores the regulatory, operational, and reputational risks of clinging to outdated credentials, especially in sectors like healthcare, finance, and manufacturing. Cottingham offers a practical, phased approach to upgrading authentication systems, including encrypted smart cards, mobile credentials, and FIDO passkeys tailored to specific environments.
