摘要: The invention discloses a card reader design method supporting radio frequency protocols in multiple types. According to the method, reading chip types is employed, and flexible switching realized through an antenna matching circuit accomplish writing of radio-frequency cards Through problem that prior art can only support fixed protocol not flexible-switching types, more solution scheme provided for security all-purpose system application.
