Is IDS R13MP is suitable for project ?

I have had it in 2009 for an industrial contract...

I remember, Melexis must have similar Chip..
Some time ago some one told me in my Bibliothek, that teir are fiished with their RFID pjoect, at these time is stopped!
He becomes lot problems /conflicts with CD`s own RFID chips...

IDS R13MP ic is suitable but it they don't have the distributors in india now from where i should get this ic ?
is any alternative available for this ic with near about same specification?

Ask IDS self, Mister Almind, www.ids-microchip.com/...

Is it a project to build a Mifare reader? You may have some idea about various Reader IC's here. Instead you may consider buying Readymade Mifare reader modules which are easily available in any component markets....Cheers
