Application guides that explain which tag, card or wristband fits a job, how to specify it and what to check before ordering.
Supply chain
RFID can identify tagged items, cases or pallets at selected points in a supply chain. Choose the identifiers and UHF labels for your trading partners' requirements, then test tag placement and reads on real loads before a production order.
Hotel key cards
An RFID hotel key card is a 13.56 MHz contactless card that the front-desk encoder writes with a room, a stay window and an access profile. The lock decides which chip it will accept, so the buying decision starts with the lock model and firmware, not with the card. This page compares the chip families in a decision table, maps the seven main lock brands (Onity, dormakaba Saflok, ASSA ABLOY VingCard, Salto, Miwa, Häfele Dialock and Be-Tech) to the card technologies they accept, and explains how to verify compatibility, migrate away from MIFARE Classic, and choose the card body (PVC, wood, bamboo, paper).
Event wristbands
RFID event wristbands replace tickets, tokens and hand stamps with a chip on the guest's wrist, and the event platform decides what each tap may do. This guide is for the project, not the band: what sits on the band and what stays on the platform, how bands are encoded and activated without slowing the gate, which chip each security level needs, whether to run single-use or reusable bands, and what to test before doors open.
NFC business cards
Whether a company is issuing NFC business cards to its staff or a reseller is selling them under its own brand, four answers carry the programme. Put a short URL on your own domain, so the cards outlive any profile platform. Encode it on an NTAG213, and use NTAG 424 DNA only when a tap has to prove the card is real. Print and encode from one file, one row per card: every card is read back, and numbered cards come with a UID list. Then approve an encoded sample before production.
Key fobs
A key fob has two jobs: every door, gate and lift reader in the estate must accept it, and nobody outside the system should be able to copy it. Both depend on the chip and on how the reader uses it. This guide is for installers, integrators and system owners choosing the credential: what a 125 kHz and a 13.56 MHz fob actually send, which chips can be cloned and which resist it, how to migrate an estate door by door, and how to prove compatibility on a sample before a volume order.
Laundry tags
An RFID laundry tag gives each towel, sheet or uniform an identifier for counting and tracking. Selection starts with the reader, fabric, attachment and actual wash process. This guide compares the constructions, sets out the wash-process specification and the test record to keep for a sample trial, and plans the pilot; no material name alone establishes wash life.
Vehicle identification
Vehicle RFID makes the barrier a non-event: a UHF tag on the windshield is read from several metres as the car approaches, and the gate is already opening. The same principle runs staff car parks, gated communities, fleet depots, weighbridges and container yards. This page explains the tag types, how the read works, where RFID beats or complements licence-plate cameras, and how to keep a tag from being moved to another vehicle.
Race timing
A race bib with a timing chip carries a passive UHF RFID tag: a thin tag stuck to or built into the bib, often on a foam layer. Antennas at the start, splits and finish of a marathon or other road race read it as the runner passes, and the timing software turns each read into a time against a bib number. This guide covers tag formats, placement, timing points, encoding and who supplies what.
Inventory and asset tracking
RFID inventory tracking counts the stock inside one warehouse or distribution centre (DC): handheld and fixed readers identify tagged items, locations and assets by radio, many at once, so cycle counts can run often enough to keep the record right. Proud Tek manufactures the tags.
Digital Product Passport
The EU Digital Product Passport (DPP) links each product to its data through a data carrier. Regulation (EU) 2024/1781 is technology-neutral and leaves the choice to each product group's delegated act. The harmonised standard EN 18220 covers QR codes, NFC and UHF (RAIN) RFID; the battery passport, the first to apply, requires a QR code.
Tool tracking
RFID tool tracking puts a tag on every tool, so a crib station, smart cabinet, doorway reader or handheld records which tool is out, who has it and where it was last seen. The hard part is the tag: tools are small, mostly metal, dropped and oiled. Proud Tek manufactures the tags; readers, cabinets and software come from your integrator.
