I have been thinking of the chip for a long time but it’s because in my country it is hard to reach. I have some questions and please answer. Is it better to have NFC and RFID chip in both hands or NExT in one hand?
The second thing that interests me if and how they have many layers? I mean if I want to have data in the chip to pay and open the door, I have to program every time data that I want to use, or can I add several uses at once?
For example I want to use it as a my Visa card and Bitcoin payments and open door to my house and maybe few more. Do I have to choose or all that can be stored in the chip at once ?
Thank You in advance.
