Em4100 125khz Rfid Card Rfid Tag 4 channel relay module takes place regardless of the125khz Rfid Card Rfid Tag used for Contactless transmission of data and supplies energy with no battery needed. Its Operating distance is Up to 100mm depending on antenna geometry. Operating frequency is 125KHz and Data transfer speed is 106 kbit s. It is featured with Data integrity of 16 Bit CRC, parity, bit coding bit counting which allows Anti collision. These cards are typically used in ticketing transaction: <100 ms including backup management.
