Smart Cards & RFID

Calypso is an open international contactless electronic ticketing standard managed by the Calypso Networks Association, operating under ISO/IEC 14443 Type B (and Type A). Developed by European transit operators to prevent proprietary lock-in with NXP MIFARE, it powers major transit networks including the Paris Navigo, Lisbon Viva, and Belgium MoBIB.

EM4100 and T5577 represent the foundational low-frequency (LF, 125 kHz) RFID transponder ecosystem. The EM4100 (EM-Marin) is a factory-programmed, 64-bit read-only identity chip, while the Atmel/Microchip T5577 is a rewritable EEPROM transponder used to emulate and clone various 125 kHz LF protocols.

FeliCa (Fast Electronic Card) is a contactless RFID smart card technology developed by Sony, standardized under JIS X 6319-4 and ISO/IEC 18092 (NFC Type 3). Operating at 13.56 MHz with 212/424 kbps Manchester encoding, it is engineered for ultra-fast sub-100ms transit gate transactions like Suica, Pasmo, and Octopus.

HID Prox and iCLASS are proprietary physical access control credentials developed by HID Global. They encompass legacy 125 kHz unencrypted Prox (such as 26-bit Wiegand H10301), 13.56 MHz read/write iCLASS smart cards, and modern Seos microprocessor cards utilizing AES-128 encryption.

ISO/IEC 14443 is the international standard governing contactless Proximity Integrated Circuit Cards (PICC) and Proximity Coupling Devices (PCD) operating at 13.56 MHz over distances up to 10 cm. It defines two distinct physical and framing architectures—Type A and Type B—and forms the foundation of EMV contactless payment cards and ICAO biometric ePassports.

ISO/IEC 15693 (NFC Forum Type 5) is an international standard for High-Frequency (13.56 MHz) Vicinity Integrated Circuit Cards (VICC). Engineered with relaxed power requirements and highly sensitive subcarrier modulation, it achieves read ranges up to 1 to 1.5 meters, making it the standard for library item tracking, ski resort passes, and pharmaceutical logistics.

MIFARE is a proprietary contactless smart card technology developed by Mikron (now NXP Semiconductors) conforming to ISO/IEC 14443 Type A. Spanning MIFARE Classic, Ultralight, Plus, and DESFire EV1/2/3, it is widely cited by NXP and industry sources as the world's most widely deployed contactless smart card platform for transit ticketing and access control.

NFC Forum Tag Types (Types 1 through 5) are standardized memory and communication specifications established by the NFC Forum, operating at 13.56 MHz. They define how data is formatted in NFC Data Exchange Format (NDEF) across underlying ISO/IEC 14443 Type A/B, FeliCa, and ISO/IEC 15693 radio architectures.

RAIN RFID (ISO/IEC 18000-63 / GS1 EPC Gen2) is an Ultra-High Frequency (UHF, 860–960 MHz) wireless standard utilizing electromagnetic backscatter coupling. Enabling simultaneous inventory reading of hundreds of passive tags per second over distances up to 12 meters, it is the global standard for retail apparel, aviation baggage, and logistics supply chains.
