QR works everywhere and fails in glare, busy cameras, and with gym members who will not open a camera app between sets. NFC is one tap. Using both is how you cover every phone without arguing about it at the front desk.

NFC tags for gym equipment.

Q: What NFC tag should a gym put on machines?

NTAG213 is enough for a URL. NTAG215/216 give more memory if you later store extra records. Gyms buy the chips and stickers themselves, then encode NFC and QR from the LIFTAG dashboard so both open the same exercise.

Q: Where should the tag go on the machine?

On a flat, clean surface at hand height, away from the weight stack’s deepest metal well if you can. The lifter should tap without crouching into the footplate. Same spot on every machine in the club so the habit transfers.

Q: Do iPhones read gym NFC tags?

iPhone XS and later read NFC tags from the lock screen and from an open app. Older iPhones and any phone with NFC disabled can still scan the QR on the same sticker.

What to put on each gym machine in 2026: NFC vs QR, tag placement, NTAG types, and how a tap opens the right exercise in a workout tracker.

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 treats NFC + QR as the default: gyms create both from the dashboard and buy the physical tags. 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

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

LIFTAG does not buy or ship those chips. Partner gyms purchase NFC tags and QR stickers, then encode both from the dashboard so they open the same catalog exercise. The floor walk is how gyms roll out NFC tags. Become a partner gym.
