Comparing:
EM4100 & T5577
FeliCa
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.
