You are using your function write() separetely for each string you try to store on the NFC tag. In your write() function you create a NDEFmessage with only that one string and you store that message to the tag.
NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to the reader in the form of electromagnetic pulses. NFC lets you share small payloads of data between an NFC tag and an Android-powered device, or between two Android-powered devices. Tags can range in complexity. Simple tags offer just read and write semantics, sometimes with one-time-programmable areas to make the card read-only.In order to understand NFC, you need to know about the NFC Data Exchange Format (NDEF), which is the lingua franca for NFC devices and tags.
