NFC Tag Ordering Guide
Buying the wrong tags for a project is one of the most expensive mistakes in NFC deployment. This guide covers chip selection, form factor decisions, quantity tiers, supplier evaluation, and sample testing before committing to a production order.
Step 1: Define Requirements Before Browsing Suppliers
Answer these six questions before looking at any product page:
| Question | Why It Matters | Tool |
|---|---|---|
| What payload size do you need? | Determines chip minimum memory | Memory Calculator |
| What device types must read the tag? | Determines NFC-A vs NFC-F vs NFC-V | Compatibility Checker |
| Will the tag be on or near metal? | Standard inlays fail on metal | Read Range Estimator |
| What is the operating environment? | Temperature, humidity, UV, chemical | Chip Selector |
| Do you need security features? | password-protection, aes-encryption, sdm | — |
| What form factor? | dry-inlay, wet-inlay, label, card, tag | — |
Run the Chip Selector with these parameters to get a shortlist before you begin supplier conversations.
Step 2: Choose Chip Family
The chip defines memory size, security capabilities, and data-retention.
| Use Case | Recommended Chip | Memory | Key Feature |
|---|---|---|---|
| Simple URL redirect | NTAG213 | 144 B | Universal compatibility |
| Long NDEF payload (vCard, Wi-Fi) | NTAG215 | 496 B | Most consumer apps handle it |
| Large payload or future-proof | NTAG216 | 872 B | Head-room for payload growth |
| Anti-counterfeiting | NTAG 424 DNA (ntag-dna) | 416 B | aes-encryption, sdm |
| Automotive / industrial | NTAG I2C Plus | 1 KB | Dual interface (NFC + I2C) |
| Long-range item tracking | ICODE SLI (iso-15693) | 112 B | read-range up to 1 m |
| Metal surface | HF Metal tag (various) | Varies | Ferrite layer built in |
| Transit / loyalty (Japan) | FeliCa RC-SA01 (nfc-f) | 208 B | FeliCa system required |
Step 3: Choose Form Factor
| Form Factor | Description | Typical Use |
|---|---|---|
| dry-inlay | Chip + antenna, no adhesive | Embedded in packaging, lamination |
| wet-inlay | Chip + antenna + adhesive liner | Apply to smooth surfaces directly |
| Paper label | Wet inlay + printable paper face | Product labels, shelf tags |
| PET/polyester label | Wet inlay + PET face | Chemical-resistant environments |
| Epoxy disc | Chip + antenna in rigid epoxy | Keychains, outdoor objects |
| PVC card (ISO CR80) | Full credit-card size | Access badges, loyalty cards |
| On-metal label | Ferrite-backed wet inlay | Metal assets, machinery |
| Laundry tag | Chip encapsulated in silicone | Garment tracking |
For embedded applications, dry-inlay gives you freedom to design a custom antenna enclosure. For stick-on applications, wet-inlay or paper labels simplify deployment.
Step 4: Understand Quantity Tiers
| Quantity | Typical Unit Price (NTAG213) | Lead Time | MOQ Notes |
|---|---|---|---|
| 1–99 | $0.40–$1.00 | In stock | Samples/eval |
| 100–999 | $0.15–$0.30 | 1–2 weeks | Trial order |
| 1,000–9,999 | $0.08–$0.15 | 2–4 weeks | Pilot production |
| 10,000–99,999 | $0.05–$0.10 | 4–8 weeks | Production |
| 100,000+ | $0.03–$0.07 | 8–16 weeks | Volume; negotiate |
Prices vary significantly by form factor. On-metal tags cost 3–5× more than plain inlays. NTAG 424 DNA costs 4–8× more than NTAG213. Run the Tag Cost Calculator with your quantity and chip to model total cost.
Step 5: Evaluate Suppliers
| Criterion | What to Check |
|---|---|
| Chip authenticity | Demand a certificate of conformance; test originality-signature on samples |
| data-retention spec | Should be ≥ 10 years (NXP NTAG spec: 10 years @ 85°C peak) |
| write-endurance | ≥ 100,000 cycles for rewritable deployments |
| Pre-encoding options | Can they encode your NDEF at the factory? At what cost per unit? |
| Serialisation | Can they print human-readable UID or custom serial on label face? |
| Custom printing | CMYK + spot UV on label face; are bleeds and dielines provided? |
| Sample policy | Free or low-cost samples before production commitment |
Step 6: Sample Testing Protocol
Before placing a production order, test a sample of 20–50 tags across the following:
- Verify uid uniqueness: scan all samples and confirm no duplicate UIDs.
- Read range: confirm spec'd range on iOS, Android, and your reader hardware.
- Write test: encode and read back 10 samples; verify byte-perfect retention.
- Environmental: expose 5 samples to your worst-case temperature and humidity; retest.
- Form factor: apply to your actual substrate (curved surface, metal, fabric); retest range.
Only proceed to production if all sample tests pass. A 2–4 week sample test cycle costs much less than a failed 50,000-unit production run.
Red Flags to Avoid
- Suspiciously cheap chips from unverified sources — counterfeit NTAG chips fail originality signature checks
- Suppliers who cannot provide a datasheet for the exact chip variant
- Pre-encoded tags where the encoding is not verifiable (no raw read capability offered)
- MOQs that force over-ordering before you have validated demand

Our guides cover a range of experience levels. Getting Started guides are written for beginners with no prior NFC knowledge. Programming guides target developers integrating NFC into mobile apps or embedded systems. Security guides are for engineers designing secure NFC deployments for payments, access control, or authentication.
Most guides require only an NFC-enabled smartphone (iPhone 7+ or any modern Android device) and a few NFC tags (NTAG213 or NTAG215 recommended for beginners, available for under $1 each). Advanced guides may reference USB NFC readers like the ACR122U or Proxmark3 for development and testing.
Yes. Programming guides include code examples for Android (Kotlin/Java with the Android NFC API), iOS (Swift with Core NFC), and web-based tools (Web NFC API for Chrome on Android). All code samples are tested and include inline comments explaining each step.
