EM4550 Card

The  EM4450/4550  is  a  CMOS  integrated  circuit  intended for  use  in  electronic  Read/Write  RF  Transponders.  The difference between EM4450 and EM4550 is that EM4550 are bumped and has megapads for the two coils. The chip contains  1  KBit  of  EEPROM  which  can  be  configured  by
the user, allowing a write inhibited area, a read protected area,  and  a  read  area  output  continuously  at  power  on.

EM4550 Card is working under low frequency 125Khz. EM4550 (Em-marine) card contains 1K-Bit of read/write memory which can be configured by the user.

EM4550 Card is great solution for access control, pre-payment systems, ticketing systems, loyalty program, time attendance systems and staff identification.

We manufacture blank cards and pre-printed cards.
