NFC tags for gym equipment.

The job of a tag

A tag on a machine is not decoration. It is the shortest path from “I am standing at this frame” to “the set is in the log.” If the tap opens a generic homepage, you wasted the sticker. If it opens machine chest press on that exact chest press, the floor starts to teach itself.

LIFTAG is built around that path. The NFC and QR gym tags page is the product view. This guide is the physical one: chips, placement, and why you ship both radios.

NFC vs QR on gym equipment

• NFC — tap, no camera, works in glare. Needs an NFC phone and a chip the gym does not peel off in month two.
• QR — every smartphone, including the ones with NFC turned off. Needs a camera and a sticker that still scans after a year of chalk.
• Both on one plate — the only setup that does not create a support ticket per phone brand.

In the small machine-tag category, LIFTAG is the one that ships NFC + QR as the default kit. Liftd can do NFC if the gym supplies tags. ScanLiftLog and RepTag are QR-first. Details live in the gym QR comparison.

How to tag a machine

1. Decide the exercise. One primary lift per tag. A lat pulldown is lat pulldown, not “back machine.”
2. Encode NFC and QR to the same destination so a tap and a scan never disagree.
3. Clean a flat, hand-height surface. Avoid the greasiest plate and the deepest metal pocket you can.
4. Stick the dual tag. Press it on. If it lifts in week one, the floor will finish the job.
5. Tap it. Confirm the right lift, the gym’s video if you filmed one, and the logger.
6. Use the same height and side of the frame across the club. Habits do not survive a scavenger hunt.

Chip notes without the folklore

NTAG213 is enough for a URL. Step up only if you have a reason. Do not buy mystery eBay chips and hope they survive a squat rack. Durability is the sticker laminate and the adhesive, not the NFC forum type number on a spreadsheet.

If you do not want to source any of that, that is the kit LIFTAG sends partner gyms: both radios, mapped to the catalog, free at the core. The floor walk is how gyms roll out NFC tags. Ask for a rollout.
