The EM4200 cards do not require a dedicated reader manufactured specifically for the EM4200 chip. In most applications, any reader that supports the EM4200 or its compatible EM4100/EM4102 communication formats and operates at 125 kHz can read the card. This compatibility is a key advantage of the EM4200. When designing this chip, EM Microelectronic positioned […]

The SLE4428 smart card can certainly serve as an access control credential—provided the access control system is compatible with its security model and contact-based operation. The SLE4428 is not a microprocessor-based smart card with advanced encryption and authentication capabilities, but rather a contact-based card; Its core configuration includes 1 KB of EEPROM storage, irreversible byte-level […]
