Overview

Store Tags are physical NFC tags that you attach to your items to verify authenticity, prove ownership, and track provenance. When scanned with your phone, a Store Tag cryptographically confirms the item is genuine and hasn’t been tampered with.
Pro Subscription Required: Store Tags and the verification system are available exclusively to Pro and Lifetime subscribers.

​
Why Store Tags?

Cryptographic Verification

Each tag uses AES-128 encryption to prove authenticity — no counterfeiting possible

Tamper Detection

Enterprise tags detect physical tampering with hardware tamper loops

Provenance Tracking

Build a complete verification history for every item over time

Risk Scoring

Automatic risk assessment flags suspicious activity like cloned tags or impossible travel

Estate & Insurance

Verified items strengthen insurance claims and estate documentation

Works Offline

Scan tags with any NFC-enabled smartphone — no app required

​
How Store Tags Work

Store Tags use NFC (Near Field Communication) technology — the same technology behind contactless payments. Each tag contains a unique identifier linked to your item in Storehouses.

​
Verification Levels

​
What Happens When You Scan

  1. You tap your phone to the Store Tag on your item
  2. The tag transmits an encrypted message with a rolling counter
  3. Storehouses verifies the cryptographic signature server-side
  4. You see a verification result with a confidence score and risk assessment
Enterprise Store Tags (NTAG 424 DNA) use the same cryptographic protocol as contactless payment cards. Each scan produces a unique, non-replayable proof of authenticity.

​

Tags ship to your address and arrive pre-programmed and ready to use

​
Claiming a Tag

When your tags arrive, you need to claim them to link them to your account:
1

Scan the Tag

Hold your phone near the Store Tag — your browser opens the claim page automatically
2

Sign In

Log in to your Storehouses account if not already signed in
3

Confirm Claim

The tag is now linked to your account and ready to assign to an item

​
Pairing a Tag to an Item

1

Go to Verification

Navigate to the Untagged Items tab on the Verification page
2

Find Your Item

Search or browse your untagged items
3

Click 'Pair Tag'

Hold the Store Tag near your phone when prompted to write the item’s registry ID
4

Attach the Tag

Physically attach the Store Tag to your item (adhesive backing, display case, storage container, etc.)

​
Verification Page

Access your verification dashboard at storehouses.app/verification. The page has four tabs:

​
Scan Tag

Scan any Store Tag to verify an item. The scanner automatically detects the tag type and routes to the appropriate verification method. After scanning, you see:
  • Verification status — Verified, Caution, Warning, or Alert
  • Risk score — 0.00 (no risk) to 1.00 (high risk) with color-coded indicator
  • Confidence level — Based on tag type and verification method
  • Anomaly flags — Any detected issues (counter rollback, impossible travel, rapid scanning)

​
Manage Tags

View all your Store Tags with their current status:
  • Active — Tag is paired with an item and working normally
  • Disabled — You’ve temporarily disabled the tag
  • Lost — You’ve reported the tag as lost
  • Compromised — The system detected potential cloning or tampering
From this tab you can rename, reassign, disable, or remove tags.

​
Untagged Items

Browse items in your portfolio that don’t have a Store Tag assigned. Use the “Pair Tag” button to assign a tag to any item.

​
Event History

View a complete timeline of all verification events across your portfolio. Each event shows:
  • Timestamp and verification method
  • Confidence level and risk score
  • Any anomaly flags that were triggered
  • The item and tag involved

​
Risk Scoring

Every scan produces a risk score from 0.00 (no risk) to 1.00 (high risk):

​
What Affects the Score

Lowers risk (good):
  • Successful cryptographic verification (strongest signal)
  • Valid rolling counter
  • Tamper loop intact
  • Scan location matches expected area
  • Photo captured during verification
Raises risk (bad):
  • Cryptographic verification failure (strongest negative signal)
  • Counter rollback (suggests cloned tag)
  • Tamper loop broken or changed
  • Impossible travel (scanned in two distant locations too quickly)
  • Rapid scanning (many scans in a short window)

​
Anomaly Detection

The system automatically monitors for suspicious patterns:
If a tag accumulates more than 3 anomalies, it is automatically marked as compromised and disabled for security. Contact support if you believe this is in error.

​
Tag Lifecycle

Store Tags move through these states:
  • Provisioned — Tag manufactured and cryptographic keys loaded
  • Shipped — Tag sent to you
  • Claimed — You scanned and linked the tag to your account
  • Active — Tag is paired with an item and in use
  • Disabled — You temporarily disabled the tag (can be re-enabled)
  • Lost — You reported the tag as lost (prevents unauthorized use)
  • Replaced — Old tag replaced with a new one
  • Compromised — System detected potential cloning (automatic)
  • Decommissioned — Permanently retired

​
Staleness and Re-Verification

Verification confidence decays over time. Items should be re-scanned periodically: Items that haven’t been verified within their staleness window show a notification on your dashboard prompting re-verification.

​
Enterprise Tags

Enterprise Store Tags use NTAG 424 DNA chips with advanced security features:

​
Cryptographic Authentication

Each scan generates a unique, non-replayable proof using:
  • AES-128 CMAC — Military-grade message authentication
  • Rolling counter — 24-bit counter increments with every scan (16M+ scan capacity)
  • Session keys — Derived uniquely per scan from the master key and counter
  • Encrypted UID — Tag identity encrypted in transit

​
Tamper Detection

NTAG 224 DNA StatusDetect tags include a hardware tamper loop — a physical wire that detects if the tag has been removed or the item opened. If the loop is broken:
  • The tag reports tampered status
  • Risk score increases significantly
  • You receive a notification

​
Best Practices

Start with high-value items where provenance matters most — rare watches, fine art, precious metals, and collectible firearms.
Periodic scans build a verification history that strengthens provenance claims for insurance and estate purposes.
Place tags where they won’t be accidentally removed but can still be scanned. Inside display cases, on storage containers, or on item packaging work well.
If a tag is lost or separated from its item, mark it as lost in the Manage Tags tab to prevent unauthorized verification.
NFC scanning works best with up-to-date phone software. Ensure NFC is enabled in your phone settings.

​
Troubleshooting

  • Ensure NFC is enabled on your phone (Settings → NFC)
  • Hold the phone close to the tag for 2-3 seconds
  • Try different positions — NFC antennas vary by phone model
  • Remove phone case if it’s thick or metallic
  • Some phones require the screen to be on and unlocked
The tag hasn’t been claimed yet. Scan it while logged in to claim it to your account.
Check the anomaly flags for details. Common causes:
  • Scanning from a new location (geo mismatch) — usually resolves on next scan
  • Long gap between scans (counter gap) — scan again to reset
  • If counter rollback or impossible travel is flagged, contact support
This happens when 3+ anomalies are detected. Contact support with your tag details — if it’s a false positive, they can restore the tag.

​
FAQ

No. Store Tags work with the built-in NFC reader on any modern smartphone. Scanning opens your browser automatically.
Anyone can scan the tag, but only you (the owner) can see the full verification details. Others see a limited verification page confirming the item is registered.
You can transfer tag ownership when selling an item. The verification history transfers with it, providing provenance to the buyer.
There’s no limit on the number of tags per account. Order additional packs as your collection grows.
No. Store Tags are passive NFC devices powered by your phone’s NFC signal. They have no batteries and last indefinitely.
