W55MID50
General Description
Nuvoton MFID (Magnetic Field Identification) series is used in all areas of automatic data capture
allowing contactless identification of objects using magnetic field. From ticketing to industrial automation
and access control, the applications of MFID are burgeoning. In recent years automatic identification
procedures have become very popular in many service industries, purchasing and distribution logistics,
industry, manufacturing companies and material flow systems.
W55MID50 is one of series in Nuvoton MFID family that supports multi-functional Reader solution
and especially focus on toy, security, and consumer related applications. The applications with Nuvoton
MFID Tag series such as W55MID10 that provides read-only mask ROM-ID version transponder for mass
production solution in toy industrial, meanwhile W55MID15 provides the other solution for manufacture
option, which is 243 bonding-ID selection transponder. Besides the single tag transponder application,
W55MID35 offers multi-transponder recognition function for intelligent and smart toy applications.
W55MID50 provides a wide variety of applications for toy, security, and consumer market
meanwhile the W55MID50 is the most cost effective solution on current MFID related application market.
