Wireless Modules

NFC / RFID Modules

13.56 MHz NFC and RFID reader modules for access control, locks, kiosks and identification products.

Overview

NFC and RFID modules read a credential and return its identifier. The engineering effort sits in three places: the antenna, the protocol coverage, and what the system does with the identifier afterwards.

We supply 13.56 MHz reader modules covering common ISO14443A/B and ISO15693 credentials, with UART, SPI and I2C interfaces. For products with a metal front panel or a very thin bezel, the antenna is the limiting factor — we design the coil geometry, ferrite shielding and matching network for the actual mechanical design.

On the software side we implement card enrolment, sector or block access where required, key management for MIFARE Classic or DESFire deployments, and the mapping between a card identifier and a user record in the app or cloud platform.

Capabilities

What this covers

01

Common credential support

ISO14443A/B and ISO15693 coverage, with model-specific support for MIFARE Classic, DESFire and NFC tag types.

02

Antenna design

Coil geometry, ferrite shielding and matching network designed for metal panels and compact enclosures.

03

Multiple host interfaces

UART, SPI and I2C options to suit the host MCU and board space.

04

Credential lifecycle

Enrolment, revocation and identifier-to-user mapping handled in the app and cloud layers.

Specification

Technical specifications

Frequency13.56 MHz
StandardsISO14443A/B, ISO15693 (model dependent)
Host interfaceUART, SPI, I2C
Card typesMIFARE Classic, MIFARE DESFire, NFC tags (model dependent)
AntennaIntegrated coil or external antenna connector
Read rangeTypically 2 – 5 cm, enclosure dependent
Supply voltage2.7 – 3.6 V
Operating temperature−25 °C to +85 °C (model dependent)

Read range is strongly affected by the enclosure, metal proximity and credential type. Range is validated on the finished mechanical design.

Applications

Where it is used

  • Smart lock card access
  • Access control readers
  • Locker and cabinet systems
  • Kiosks and self-service terminals
  • Industrial asset identification
  • Loyalty and membership devices

Questions

Frequently asked

Can the reader work behind a metal front panel?

Yes, with a ferrite shield and a correctly tuned antenna. Metal detunes the coil, so the design has to be validated on the actual panel, not on a bare PCB.

Do you support encrypted MIFARE DESFire credentials?

Support depends on the reader model and the key management scheme. We confirm the credential type and security level before selecting a part.

Can the same module read phone-based NFC?

Yes for NFC-capable phones, subject to the antenna design and the phone’s antenna position. We test with representative handsets.
