EM4200 cards are contactless RFID cards operating at a low frequency of 125 kHz. They have read-only memory and a unique identifier (UID).
EM4200 read-only badges offer high performance in several applications, such as access control and identification at hotels and campsites; waste management (opening of access-controlled bins using RFID cards); loyalty programmes; and as electronic wallets for payments at laundromats, vending machines and self-service car washes.
EM4200 cards are available in three different materials (PVC, PETG and wood), in the following dimensions: 86 mm x 54 mm x 0.86 mm for PVC and PETG, 86 mm x 54 mm x 1.3 mm for wood.
