RFID & NFC guides and resources
Independent, practical guidance to help you choose the right RFID and NFC products — from frequencies and chips to materials and hardware.
Complete guides
RFID Cards guide
RFID cards combine a chip and antenna inside a card body to enable contactless access, payment, ID and loyalty. This guide covers frequencies, chips, materials, printing and how to specify the right card.
NFC guide
NFC is short-range 13.56 MHz technology built into every modern phone. A tap can open a link, verify a product or share data — no app needed — which makes NFC ideal for marketing, authentication and access.
Labels & Inlays guide
RFID labels put a chip and antenna into a thin, applicable format for tagging items at scale. The choices are frequency (HF or UHF), inlay type (dry or wet) and face (blank or printable).
RFID Blocking guide
RFID-blocking products stop unauthorized 13.56 MHz reads of contactless cards. Passive shields detune the field; active cards emit a jamming signal. A single card, sleeve or wallet lining protects what is around it.
Readers & Hardware guide
RFID readers come as desktop encoders, fixed readers with antennas, and handhelds — across LF, HF and UHF. The right choice depends on frequency, range, interface and whether you need an SDK to integrate.
Wristband Materials guide
Silicone is the durable, waterproof, reusable choice; woven fabric suits multi-day festivals; Tyvek paper is the low-cost single-use option; vinyl is tough and adjustable. Match the material to the event length, environment and budget.
Key Fob guide
An RFID key fob is a durable keyring token with an embedded chip for contactless access, membership and identification. The right fob comes down to frequency (LF, HF or UHF), chip and shape.

LF vs HF vs UHF
LF (125 kHz) suits short-range access and animal ID; HF/NFC (13.56 MHz) suits tap cards, tickets and libraries; UHF (860–960 MHz) suits long-range, bulk reads in retail and logistics.
RFID vs NFC
NFC is a short-range (≈4 cm) subset of 13.56 MHz HF RFID built for two-way phone interaction. "RFID" more broadly also covers LF and long-range UHF used for tracking and inventory.
RFID vs Barcode
Barcodes are cheap but need line of sight and one-at-a-time scanning. RFID reads many tags at once, without line of sight, and stores re-writable data — at a higher per-tag cost.
MIFARE vs NTAG vs DESFire
NTAG is the go-to for NFC phone tap and marketing; MIFARE Classic suits access and closed-loop transit; DESFire is the secure, encrypted choice for payment, transit and high-security ID.
Dry vs Wet Inlay
A dry inlay is the chip-and-antenna with no adhesive — for laminating or embedding. A wet inlay adds adhesive so you can peel and stick it straight onto products.
Card Materials
PVC is the economical default; PET/PETG and PC add durability and security; eco/BIO and wood cut plastic; metal signals premium. The right pick balances durability, look, sustainability and cost.
NFC vs RFID Wristband
HF/NFC wristbands work at a tap (a few centimetres) for cashless payment, access and phone/social interaction; UHF RFID wristbands read from several metres for automatic gate access and crowd tracking. Most events use HF/NFC.
NTAG213 vs 215 vs 216
The three chips are near-identical except for user memory: NTAG213 holds 144 bytes, NTAG215 holds 504 bytes and NTAG216 holds 888 bytes. Pick 213 for URLs, 215 for vCards and gaming, 216 for the most data.
UHF vs HF Labels
UHF labels (860–960 MHz) read from metres away and scan hundreds at once — ideal for retail and logistics. HF labels (13.56 MHz) read at a few centimetres, are phone-readable, and suit libraries, pharma and NFC marketing.
