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.

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.
