+1 for AliExpress

Just check which type, some are an older protocol or something and only work with some phones. If they say note 4 on them then they should be all good.

Jumping in on this thread, what is the best app to write to these tags (Android)?  Will just be simple things like changing state on BT, WiFi etc

The one I use is NFC TagWriter by NXP https://play.google.com/store/apps/details?id=com.nxp.nfc.tagwriter&hl=en

Hunter: If you want to have a play with them, easiest is to use a hotel key card.
Only some key cards work, had a stack of them, and found only 5 that works.
Otherwise use AtHop card, for $5 you can have a programmable card.

Not all NFC is the same, apparently some have lower memory or something.
I got my sister to drop by store near her place in London to pick up a selection pack of them.
Wrist band, stickers, key tag, micro tag etc pack of 50
Unfortunately their shipping charges make them not worth it to ship to NZ.

I use Trigger, available on Play Store, with the larger capacity tags, can program 2 function per tag

Buy AT Hop Card

To answer my own question, I'm currently playing with NFC ReTag FREE https://play.google.com/store/apps/details?id=com.widgapp.NFC_ReTAG_FREE&hl=en - stores a tag database locally on the device, so you can use any NFC tag to trigger any action on your device.

NFC tags look like a good thing to play with... The Type 1 tags can store 96 bytes and can be encrypted..

Ah... My Moto G3 phone does not have NFC...

So looking at the ACR122U-A9 reader writer from Aliexpress at US$28.39 looks pretty good...

Possibly for the locators that you can get when you choose to use the create your own, that would let them ID the table so they know where to bring the food?

Bought myself a ACR122U NFC reader from Aliexpress to play with.

After much messing around I found that Windows 10 automatically recognises the reader and the NFC card.

To write/read to the card I got hold of:

GoToTags.WindowsApp-v3.3.6.0.msi

Found here:

Hope that helps other beginners.
