Desktop HF / NFC reader
Desktop / benchtop
What is it?
A desktop HF reader is a small flat pad or puck that reads and writes HF (13.56 MHz) and NFC tags placed on or near its surface. Plug it into a laptop via USB and it works like a contactless card reader - used for encoding RFID badges, testing NFC tags during development, programming library books, or authenticating smart cards. Desktop HF readers are the most common first RFID reader that developers and system integrators buy.
How it works
The reader contains a flat coil antenna that generates a 13.56 MHz magnetic field extending a few centimetres above the pad surface. When an HF or NFC tag enters this near-field zone, inductive coupling powers the tag and enables bidirectional data transfer. Desktop readers support ISO 14443 (NFC-A/B), ISO 15693 (NFC-V / ICODE), and FeliCa protocols. Most present as a USB HID or virtual COM port, making them plug-and-play on any operating system. Reader SDKs allow full control over tag memory - reading, writing, locking, and password-protecting data blocks.
Industries
Use cases
- Encoding and programming access badges
