EM4305 cards are contactless RFID cards operating in the low-frequency band at 125 kHz. They transmit data in read/write mode, have a 64-byte memory and a unique identifier (UID). The memory is password-protected in read/write operations.
EM4305 cards are used for access control and identification in the hospitality industry, corporate and educational settings, and also in the waste-management sector for opening access-controlled bins using RFID cards.
They are available in three different materials (PVC, PETG and wood) in the following sizes: 86 mm x 54 mm x 0.86 mm for PVC and PETG, 86 mm x 54 mm x 1.3 mm for wood.
