RE40 RFID Module

The easy way to integrate Zebra’s industry-leading RFID technology

Easily and cost-effectively add Zebra’s advanced RFID capabilities into your products with Zebra’s first highly-integrated OEM RFID UHF module, the RE40. This system in package (SIP) solution provides everything you need to make every aspect of integrating RFID into your products as simple as possible — from manufacturing and design to testing and certification. The result? Fast integration for a fast time-to-market. Easy firmware updates for longer product lifecycles. And devices that set the bar for simplified management.

Two variants to meet diverse needs

The RE40 is available as a SIP surface mount module or SIP module mounted on a PCB for easier integration. The SIP surface mount module is available in two packaging formats: a tray for small quantities and Tape and Reel to support high volume manufacturing.

Industry-leading radio technology

Get peak reliable RFID performance for reading and writing with superior radio sensitivity, an echo-cancellation noise reducing circuit and powerful software for a wide variety of applications. The RE40 supports Dense Reader Mode (DRM) operation and high speed reading of up to 250 tags per second.

Tiny size fits in virtually any product

As one of the smallest RFID chip modules in this class, the RE40 can fit on the most space constrained boards in the most space constrained products — ideal for fixed and portable applications.


Shock testing and a wide temperature range from subzero to extreme heat ensures reliable operation in many environments.

Simple device deployment — no expertise required

Zebra’s 123RFID Desktop no-cost utility makes it easy to configure and manage your RFID-enabled devices. An intuitive wizard presents easy-to-understand options in drop-down menus, radio buttons and sliders that let you simply click your way through set up. And with built-in help and how-to videos, practically any question can be answered right inside the tool.

Lightning fast development

The Development Kit Radio Engine (DKRE) allows you to rapidly test the RE40 RFID capabilities and develop RFID applications. This kit contains everything you need to get started and even read tags in minutes. The kit includes: a development board with two RF ports, a serial and USB port and a power connection; antennas; RF, USB and power cables; sample tags; a Quick Start Guide; USB drive; and RF modules.

Low power consumption

Support for a wide operating voltage range and lower power consumption are ideal for portable applications.

The RE40 — the quick, easy and cost-effective way to empower your products with Zebra’s advanced RFID capabilities.
