Now , I know how to do NFC from Android-to-Android. But if I want to do it from Android to another device which has an NFC tag then please tell me-
(a) A very good NFC chip maker?
(b) If I get one, then how do I program it?
One of the largest manufacturer of NFC devices is NXP Semiconductor. They have a variety of different tags that can be purchased from commodity electronics vendors. Here is a link to their NFC site: http://www.nxp.com/campaigns/nfc/
