RFID CARD often avoid or delay change due to concerns about budget and the impact on productivity and workflow. This can be especially dangerous, however, in the access control infrastructure, where a combination of technology obsolescence and escalating security threats can quickly cripple an organization’s ability to protect its people, facilities and data assets. It is far more effective to be proactive, rather than reactive, about change. This requires building an infrastructure that presumes and prepares for ongoing change to support evolving access-control needs, and enables the organization to preserve investments in its current infrastructure as it moves to new technologies and capabilities.
There are many reasons to embark on this path, including upgrading inadequate security and enhancing investment value and user convenience with a platform that supports multiple applications on smart cards or combo cards. The ability to embrace the positive aspects of change requires an access control platform that can meet today’s requirements with the highest levels of security, convenience and interoperability while enabling organizations to adopt future capabilities without disrupting ongoing business operations.
Interoperability and leveraging standards
Building an architecture that supports change requires careful attention to the “connections” between the architecture’s components. As components evolve — i.e. adding new equipment and systems, revisions and upgrades to existing systems — it can be a challenge to ensure that the components continue to function and deliver the expected security functionality that was originally intended. The evolution of standards within the security industry is a direct result of this challenge, and organizations such as the SIA, The Smart Card Alliance, PSIA and ONVIF are leveraging the industry’s expertise to address these challenges. A prime example of these efforts is the Open Supervised Device Protocol (OSDP) and associated Secure Channel Protocol (SCP) forcontactless cards communications that have been standardized by the Security Industry Association (SIA).

Radio-Frequency Identifier RFID CARD) technology, using the ISO-14443 standard, is becoming increasingly popular, with applications like credit-cards, national-ID cards, Epassports, and physical access control. The security of such applications is clearly critical. A key feature of RFID-based systems is their very short range: Typical systems are designed to operate at a range of 5-10cm. Despite this very short nominal range, Kfir and Wool predicted that a rogue device can communicate with an ISO-14443 RFID tag from a distance of 40-50cm, based on modeling and simulations. Moreover, they claimed that such a device can be made portable, with low power requirements, and can be built very cheaply. Such a device can be used as a stand-alone combo cards skimmer, to surreptitiously read the contents of simple RFID tags. The same device can be as the "leech" part of a relay-attack system, by which an attacker can make purchases using a victim's RFID-enhanced credit card—despite any cryptographic protocols that may be used.
In this study we show that the modeling predictions are quite accurate. We show how to build a portable, extended-rangecontactless cards skimmer, using only electronics hobbyist supplies and tools. Our skimmer is able to read ISO-14443 tags from a distance of ?25cm, uses a lightweight 40cm-diameter copper-tube antenna, is powered by a 12V battery—and requires a budget of ?$100. We believe that, with some more effort, we can reach ranges of ?35cm, using the same skills, tools, and budget.
We conclude that (a) ISO-14443 RFID tags can be skimmed from a distance that does not require the attacker to touch the victim; (b) Simple RFID tags, that respond to any reader, are immediately vulnerable to skimming; and (c) We are about half-way toward a full-blown implementation of a relay-attack.
