We have mifare reader module which is based on mfrc500. 


Now we are planning to develop new mifare module, for that we want a reader ic which satisfy below requirements:

1.) backward compatible with mfrc500

2.) support new card types

3.) reading range must be > 100mm

4.) must be in production for 5years


We found below reader ic,

1.) CLRC632

2.) MFRC531

3.) MFRC530


Are these module recommend for new design? and what about there availability/production?
