Elcom Industries MAG-723D-I Card Reader

The MAG‑723D‑I is a magnetic stripe card reader used in industrial access control systems. Common failure modes for this class of devices include degraded read head contact, power supply voltage drops, and firmware corruption due to environmental stress. First‑check steps: verify the 12 V DC input rail with a multimeter; inspect the read head and connector pins for corrosion or mechanical damage; review any error logs from the host controller for communication timeouts or CRC errors.[oss-gpt-20b]
