Crew members tap their phone to clock in — faster than opening an app — and GPS is captured automatically on every tap. No kiosks, no tablets, no hardware to maintain.

VERIFIED ### From Tap to Verified Punch One tap on an IronClock Smart Tag clocks a crew member in — and stamps the punch with GPS automatically. Nothing to log in to, nothing to set up. #### Mount the Smart Tag Stick an IronClock Smart Tag at the site entrance, gate, or job trailer. It's a thin, weatherproof tag — no power, no wiring, no kiosk to bolt down. #### Crew Members Tap to Clock In A crew member taps the back of their phone to the tag. The clock-in fires instantly — faster than unlocking a phone and opening an app. #### GPS Captured Automatically On every tap, IronClock records the exact GPS coordinates and timestamp. The punch is stamped to the site, not just the tag. #### Verified, Not Spoofable Because the tap and the GPS lock both have to happen on site, there is no way to clock in a crew member who is not there. Buddy punching stops at the gate. ### Cheaper, Faster, Harder to Cheat A Smart Tag does the job of a kiosk for a few dollars — with nothing to charge, update, or replace. #### Faster Than an App No login, no menu, no scrolling. A crew member taps the tag on the way in and the punch is already recorded. Throughput at a busy gate stays high even with a full crew arriving at once. #### No Kiosks, No Tablets, No Hardware to Maintain An IronClock Smart Tag has no screen, no battery, and no network connection to fail. There is nothing to charge, update, reboot, or replace when the weather turns. Mount it and forget it. #### GPS Captured on Every Tap Each tap records GPS coordinates and a precise timestamp automatically. You get verified location proof on every punch without asking the crew to do anything extra. #### A Few Dollars per Tag Smart Tags cost a few dollars each — not hundreds or thousands like a hardened kiosk. Tag every entrance, gate, and trailer across all your sites without a hardware budget. #### Buddy Punching Becomes Impossible Pair the tap with GPS and a clock-in can only happen where the tag is. A crew member cannot punch in for someone parked across town — physical presence is required. #### Re-tag a New Site in Minutes Spinning up a new job site? Peel, stick, and assign. Tags are reusable across sites and need no installer, no electrician, and no IT ticket. ### Tag Your Sites. Skip the Kiosks. Put an IronClock Smart Tag at every gate for a few dollars each and get verified, GPS-stamped clock-ins from day one.

Mount an NFC Smart Tag at the site entrance, gate, or trailer. A crew member taps the back of their phone to the tag and is clocked in instantly — faster than opening an app. IronClock captures the GPS coordinates and timestamp automatically on every tap. ### What hardware do I need for Smart Tags? Just the Smart Tags themselves and your crew's existing phones. There are no kiosks, tablets, power, wiring, or network connections to install or maintain. The tags have no screen and no battery, so there is nothing to charge, update, or reboot. ### How much do Smart Tags cost? Smart Tags cost only a few dollars each — far less than a hardened time-clock kiosk that can run hundreds or thousands of dollars. You can tag every entrance, gate, and trailer across all your job sites without a hardware budget. ### Can crew members buddy-punch with Smart Tags? No. Because the tap and the automatic GPS lock both have to happen on site, a clock-in can only occur where the tag physically is. A crew member cannot punch in for someone who is not present, which eliminates buddy punching. ## Capabilities - Tap-to-clock-in NFC Smart Tags - Automatic GPS capture on every tap - No kiosks, tablets, or hardware maintenance - A few dollars per tag - Buddy-punch prevention with GPS verification - Reusable tags across job sites
