Did you mean: 

the possible maximum reading distance with ST25R3916

We are developing a IC card skipass Reader product for ski resort market. 

I checked TRF7961 from TI, but it can provide only 200mW output power.

In the datasheet of ST25R3916, this IC can give up to 1.7W output power.

I wonder these two are same index or not. I would like to know the maximum reading distance with ST25R3916. Could you give me some information or advice?

If possible, we want a distance about 30cm. With TRF7961, about 15cm can be obtained.

Thank you very much for your help in advance.

Dear Ulysses,

thank you for your quick reply.

I got it. I will try to use a 5V power source.

best regards
