(February 2026)"]]>10Cups. We pretty much all buy the same type of coffee, every time. So I added a simple NFC reader to the barista's Kitchen Display. You buy ten cups of coffee, they give you a NFC sticker for your travel mug. Tomorrow, you skip the queue, hand the barista your travel mug. They tap it on the reader, see how you like your coffee, and redeem one.

Makes your regular's lives easier, and you take regulars out of your queue.

No stupid loyalty apps, no QR Codes, no sign ups.

More "How are you?" and less "Flat White, please"

Here is an article I wrote about it
