Which tool to read mileage from BMW EWS CAS key?

I’m  looking for a tool to read mileage from BMW KEY from BMW E91 year 2007. I want only read it not change it.
Someone knows which tool i can do that? I heard that Tango will do, but i am not willing to spend that money if only need to read it. AK90 key programmer possible?

BMW expert solution:

AK90+ will identify keys for all EWS and CAS , showing VIN , key No. and mileage from 1995-2009.

BMW AK90 key programmer can read km from key.  I read some for E46 2005 before. I test E91 2007 today. It reads no problem.

But if you need to change/correct mileage on E9x, you can go for Tango key programmer or  Digimaster 3 odometer correction master.
