I want to be able to send and receive information in a single touch.

I followed this tutorial to on using NFC to send info: http://android-er.blogspot.com/2014/04/communication-between-android-using-nfc.html

It works great but I am only able to send information from one phone at a time. So if I want to say transfer phone numbers by touching phones it has to be done twice, once to send from phone A to phone B and once to send from phone B to phone A. Is it possible to reduce this to a single touch?

There is one way that I know which can achieve this.

For android device 4.4 and after. You can use NfcAdapter to restrict an android device to Reader Mode. Once touch another device which has set with HCE tag, you can transceive data and get a respond data. it's a bidirectional communication.

For more information, you can check this.
