Dear customer,
How are you?
I would like to help you with this project, I have strong experience with MIFARE cards and smart card readers, using MIFARE cards as payment form and access control.
The phone (smart phone with NFC interface) can be used with the following specs:
-- Smart phone with NFC interface
-- Android app using NFC interface for read and write MIFARE cards.
-- If the MIFARE card has the specific values (authentication, keys, values) and is accepted, then, the app can send signals (messages, commands or others) to machine.
I would like to know more about the general functionalities.
Regards.
