Hey everyone,
I wondered if it's possible to make two small devices of the size of keyring pendants, that are able to communicate wireless with each other. This means, when I hold one device close to the other, it should read the information stored on the other device, for example a name, without the connection of a cable. If I understood it right you always need one big device for NFC like a cell phone to build up a magnetic field. What else than NFC could I use?
