EM4305 chip data modulating and transmission is coded by Manchester modulation format. Because EM4305 is less disturbed by water and metals, EM4305 RFID Tags is widely used in:

• access control in campus,
• community
• library
• parking plot
• Animal Identification according to ISO FDX-B
• Pigeon races standard
• Waste management standard (BDE)
• Industrial
