RFID & NFC guides and resources
Practical, hands-on guidance from our engineering and sales team to help you choose the right RFID and NFC products — from frequencies and chips to materials and hardware.
Complete guides
RFID Cards guide
Start with what the card must do and the system that will read it. Hotel keys, printed credentials and NFC business cards need different checks. Use this guide to choose a product route, assign printing and encoding responsibilities, and agree a working sample before a bulk order.
NFC guide
Start with what the buyer should do after a tap. For a public web page, test an NDEF HTTPS link on the intended phones, then confirm the card or label, encoded data and physical sample. Phone support, memory, write protection and website ownership are separate decisions; a working sample is the basis for agreeing the bulk specification.
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 low-power interference signal in the 13.56 MHz band. 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
Start with the installed system and the task the fob must perform. Frequency is a starting point; the chip, credential format, issuing workflow and sample results also matter.
Price guide
Use the table to compare indicative price ranges where shown. Custom printed RFID cards, NFC business cards and hotel keycards are quoted to specification. Share your card or tag requirements, quantity and delivery country so the written quote can confirm the configuration, unit price and applicable minimum order.
How to Order guide
Start with your application, quantity by design and delivery needs, even if the chip is unknown. Confirm the proposed specification and commercial terms in writing, agree the sample and approval stages, then confirm production and shipping dates. Sample charges, minimum orders, payment terms and warranty coverage depend on the agreed order.
MOQ & Samples guide
Specify the quantity for each design and construction, including any trial batch. The table provides starting references where shown; custom printed RFID cards, NFC business cards and hotel keycards require a specification-based quote. Confirm sample availability, charges and timing separately from the bulk order.
Card Printing guide
Buy finished custom printed RFID cards, or print and personalise suitable blank cards in house. The right route depends on when your artwork and cardholder data are ready, who handles encoding, and which printer and reader the cards must work with. Use this guide to prepare the brief and agree a working sample.

Original reference data: frequency, read range, chip memory and material temperature limits.
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
Start with the task and the equipment that will use the card. A phone link, a replacement hotel key and an application credential have different requirements. MIFARE includes Classic, DESFire and Ultralight families; a family name alone is not an order specification. Use the comparison below to identify the next decision.
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
NTAG213, NTAG215 and NTAG216 provide 144, 504 and 888 bytes of user memory. Choose from the actual encoded data and application requirements. “Business card”, “vCard” or “gaming” is not a byte count, and extra memory alone does not establish compatibility or a better phone experience.
MIFARE Classic vs DESFire
For replacement cards, start with the installed system’s approved credential specification. For a move from Classic to DESFire, plan the reader, issuing software, application data and key management together. DESFire offers different data and security capabilities; it is not a drop-in substitute established by the card shape or frequency.
MIFARE vs NTAG
For a card that opens a web link on customers’ phones, NTAG213/215/216 is a useful starting point. For an existing access or issuing system, use its approved credential specification. MIFARE is a family name, and NDEF is a data format: neither “MIFARE cannot work with phones” nor “NTAG works on every phone without an app” is a reliable buying rule.
T5577 vs EM4200
EM4200 uses a factory-programmed read-only code. Microchip ATA5577C supports configuration and data writing, subject to its delivered configuration and lock state. This is a starting point for selection: a matching frequency or chip name does not establish that a finished card will work in your system.
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 when built on NFC-compatible chips such as NTAG, and suit libraries, pharma and NFC marketing.
