RFID (Radio Frequency Identification)

Radio Frequency Identification uses electromagnetic coupling between a reader and a tag to identify items at short to medium range. RFID is used in access control, supply-chain tracking, contactless payments, and transit cards. Many low-cost RFID systems use weak or no cryptography and have been documented as cloneable, requiring system-level controls to compensate.

RFID in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

Security controls span signaling firewalls (SS7/Diameter/GTP screening), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36.

To place RFID in the wider telecom-security picture, review MAC, WCDMA, AP, HTTPS, OFDMA and SMPP: each entry cross-references back to this page so you can walk the topic in either direction.
