My favorite household NFC usage? NFC alarm clock.

Makes me get out of bed and tap my phone on a specific NFC tag placed somewhere around the house, in order to turn off the alarm. Then, I may as well wake up, since I'm already out of bed : )

It's a nice companion to help perform 'habit stacking' as Atomic Habits calls it. Want to do pushups right after waking up? Place an NFC card under your workout mat, so you're forced to the mat first thing in the morning.

I use "alarm clock xtreme" on Android that is similar; it has math and "type these random characters" puzzle as well as snooze detection so you hit "I'm awake" but also includes snoozing/stopping via number of steps detected or by scanning a barcode etc. Definitely recommend it.

But even so, I wish it would force me to key in the current time to disable, that way my sleepy brain would better understand "it's time to wake up now, because it is x time".

Neat, but is there an advantage between this and "Place the alarm clock further from the bed"?

The noise maker (alarm) is still close to him.

Fair. My mother used to put one of those old rattling alarm clocks with two bells on top into a metallic dish and placed that combo at the other end of the room. Similar concept.

Not a huge advantage, but I'd say mostly range and flexibility. You may want to put the tag farther away than you could hear an alarm clock, if you want to go to another room. And you could customize the alarm so you're guided towards a different tag every day of the week, without needing multiple (or any) alarm clocks.

I have one set up with guest WiFi credentials, and somehow it's still a novelty to my friends when they visit for the first time!
