Dear All,

We are designing a product which calculates some of the data based on input configured by user. Once it got configured, software will update the calculated parameters automatically. 

However to configure and transfer data to external world, we would like to use NFC in our product. Can anyone suggest best part number to do so and is NFC suitable for such information sharing application?

This application doesnt require continuous monitoring, This is like once in a year and want to select cheapest technology for the same. 

Please suggest the same.

Dear Pratik Shah,

Could you please provide more details about your setup and use case?

Is the data transfer managed time to time like at the end of the day?

My proposal is to use a NFC reader like the ST25R3911B on one side and a dynamic NFC tag such as ST25DV-I2C on the other side.

The ST25DV-I2C dynamic tag can be connected to an embedded micro-controller through a I2C interface.

All information about those 2 products is on ST web site: www.st.com/st25.

Thanks and regards
