125kHz RFID Readers

Read-only 125kHz proximity card readers for EM4100, TK4100 and SMC4001 cards and key fobs: USB keyboard-emulation pads, DB9 RS232 serial readers, a USB stick and a keypad reader. Most read up to 80 mm and output a 10-digit decimal number.

9 models

13.56MHz NFC & HF RFID Readers

Nine read-only 13.56MHz RFID and NFC readers for MIFARE Classic, NTAG and ICODE cards, in desktop, USB stick and keypad formats. Most read the card UID at up to 80 mm (the keypad model up to 50 mm) and pass it to your software as keyboard input or serial data.

9 models

UHF RFID Desktop Readers

Four USB desktop reader/writers for EPC Gen2 UHF tags, for issuing, encoding and checking tags at a desk. Each reads up to 0.5 m, writes up to 0.2 m and types tag data as a USB keyboard, with a virtual COM build on request.

4 models

UHF Integrated Long-Range Readers

All-in-one UHF RFID readers with a built-in 7–12 dBi antenna for vehicle gates, parking lanes and logistics entries. Five models cover 0–5 m to 0–20 m rated range, with Wiegand 26/34, RS232/RS485, USB and optional TCP/IP output.

5 models

Handheld & Bluetooth RFID Readers

Battery-powered RFID readers that send card and tag IDs to phones, tablets and PCs over Bluetooth or a 2.4G receiver. Choose a pocket reader for 13.56MHz or 125kHz cards, or one of four UHF handhelds, two with a barcode scanner.

5 models

USB-C / OTG Phone RFID Readers

Plug-in readers that connect straight to the USB-C port of an Android phone or tablet, take power from it and type the card or tag number into any app. Three models cover 13.56MHz NFC, 125kHz EM4100 and UHF EPC tags.

3 models

134.2kHz Animal ID Readers

Read-only RFID readers for ISO 11784/11785 FDX-B and 125 kHz EMID animal tags: OLED handhelds with memory, a tag and barcode combo, USB desk readers, a USB-C phone plug-in and a 40 cm RS232/RS485 panel for feeders and races.

7 models

Wiegand Access Control Readers

Resin-potted wall readers that send the card number to a door, attendance or parking controller over Wiegand 26 or 34. The L410-W reads 125 kHz EM4100/TK4100 cards, the H410-W reads MIFARE Classic, and the D410-W reads both (availability confirmed in your quotation).

1 model

QR Code + RFID Access Readers

86 × 86 mm wall readers that decode visitor QR codes and read staff EM or MIFARE cards, then pass the result to a door controller, turnstile board, elevator controller or PC. Choose the slim Q420-M on flying leads, or the Q430-M with a terminal block and USB.

2 models

Magnetic Stripe Card Readers

Read-only USB swipe readers for ISO magnetic stripe cards. Choose the compact M170-U for tracks 1, 2 and 3 with driver-free keyboard output, or the long-body M180-U for Track 2 membership and ID numbers.

Why work with Henrium

Reader hardware that fits the system you already have

We focus on one thing: card and tag readers. That means we can tell you exactly which cards a model reads, what it outputs and how it connects — before you place an order.

  • Read-range and card tests

    Send your own cards or tags and we check compatibility and read distance on the model you are considering.

  • Output that matches your software

    Decimal or hex, byte order, prefix/suffix, Enter key, Wiegand 26 or 34 — configured before shipment where the model supports it.

  • The interfaces you already use

    USB keyboard emulation, USB-C/OTG for Android, Bluetooth, RS232, RS485, Wiegand and TCP/IP, so you can match the reader to your existing host.

  • OEM / ODM programmes

    Private label, frequency band and display-language options for distributors and device makers — scoped in your quotation.

125kHz vs 13.56MHz: Which RFID Card Reader Do You Need?

A 125kHz reader reads only 125kHz proximity cards such as EM4100 and TK4100. A 13.56MHz reader reads only HF cards such as MIFARE Classic, NTAG or ICODE. Neither reads the other's cards, so identify the card first. Match existing cards; for a new project, 13.56MHz offers more chip choice, on-card memory and phone compatibility.

Animal ID

Can You Scan a Microchip with Your Phone? Pet Chips, NFC and 134.2kHz

No. A phone's NFC works only at 13.56MHz, while ISO pet microchips work at 134.2kHz, so no app can read an implanted chip with the phone alone. A phone can show the number if you add a 134.2kHz reader: a USB-C plug-in for Android, or a handheld scanner that sends the ID over Bluetooth.

Technology explained

EM4100 vs TK4100 Cards: How the 64-Bit ID Becomes a Card Number

EM4100 and TK4100 are interchangeable read-only 125kHz chips. Each sends one thing to a reader: a fixed 64-bit code carrying a 32-bit ID number. The card has no writable memory and no security. Readers show the ID as a 10-digit decimal, 8-digit hex or Wiegand facility and card number, so pick the format your system stores.

Animal ID

FDX-B vs HDX Animal Tags: How They Differ and What Your Reader Must Support

FDX-B and HDX are the two ways ISO 11785 lets a 134.2kHz animal tag send the same 64-bit ISO 11784 ID. An FDX-B tag replies while the reader's field is on. An HDX tag stores energy, then replies while the field is off. A reader reads HDX tags only if it supports HDX.

UHF RFID

Fixed vs Handheld UHF RFID Readers, and Where Integrated Readers Fit

Choose by what moves. If tagged vehicles, pallets or people pass a fixed point, use a fixed or integrated reader. If staff walk to tags on shelves or assets, use a handheld. If a person presents one tag at a desk, use a desktop reader/writer. An integrated reader houses reader and antenna together, so it installs as one unit.

Animal ID

ISO 11784 and 11785 Explained: How the 15-Digit Animal ID Number Is Built

ISO 11784 defines the 64-bit code stored in an animal RFID tag. ISO 11785 defines how a 134.2kHz reader powers the tag and receives that code, by FDX-B or HDX. Readers usually show the code as 15 digits: a 3-digit country or manufacturer code, then a 12-digit national ID.

Frequently asked questions

Which RFID reader do I need for my cards?

Start with the card frequency. 125kHz proximity cards (EM4100/TK4100) need an LF reader, MIFARE and NTAG cards need a 13.56MHz reader, and EPC Gen2 labels need a UHF reader. If you are not sure, send us the card or a photo of it and we will confirm the type before you order.

Do your USB readers need a driver or SDK?

Most USB, USB-C and Bluetooth models in the catalogue work as a keyboard: the card number is typed at the cursor in the application that has focus, with no driver. Serial (RS232/RS485), Wiegand and TCP/IP models are integrated through the controller or your software; UHF long-range readers come with an SDK.

Can the output format be changed to match my software?

Yes. Most 125kHz and 13.56MHz USB readers output a 10-digit decimal number by default (the Bluetooth pocket readers default to 8-digit hex), and alternative formats such as hexadecimal, a different byte order or an added Enter key can be configured before shipment. Tell us what your software expects and we confirm whether the model can output it.

Can I order samples before placing a volume order?

Yes. Sample units are available for evaluation so you can test your own cards, range and software. Sample pricing and shipping are confirmed in your quotation.
