Frequently asked questions

The All-in-One, PlugNGo™ Long Range RFID Reader is compatible with most existing access control systems and software, making for an easy transition. Because it natively outputs globally compatible 26-bit Wiegand, you won’t need external converter devices or convoluted workarounds.

The All-in-One, PlugNGo™ Long Range RFID Reader

How does the PlugNGo™ Long Range RFID reader work?

It self adjusts continually based on local wireless conditions. So while a previous generation RFID reader had to be delicately tuned for its site and adjusted to changing site conditions, the PlugNGo™ Long Range RFID Reader handles it all for you.

What parts do I need to buy to have an operational system?

The All-in-One, PlugNGo™ Long Range and Extended Long Range RFID Readers comes with a UHF antenna, the RFID reader board enclosed in an attached, secured outdoor-rated enclosure, power supply, and a 10ft cable harness.


There is no need to pick out parts from a laundry list of parts, and hope you get them all to have an operational system. You get one part number to have an operational RFID reader.

What's the read range?

Up to 40 feet when paired with our genuine, premium HeadlightSticker™. The PlugNGo™ Long Range RFID Reader is well suited to long range reading of passive RFID tags, and can easily read multiple lanes of incoming traffic.

However, as a security best practice, we advise that you angle the reader so it can only “see” one vehicle at a time. This prevents unauthorized vehicles from gaining access because the car behind them has a valid tag.

The reader is angled in such a way to only detect the first vehicle in front of the barrier arm. If it was positioned to read the whole lane, the blue vehicle’s valid credential might permit the invalid red vehicle to enter.

System Compatibility

Can the PlugNGo™ Long Range RFID Reader work with existing tags?

In many cases, yes. The reader natively understands 26-bit Wiegand protocol RFID devices: the universal language of access control. While this protocol is a huge standard, some RFID dealers opt to encrypt their tags with proprietary formats to force you to keep buying their readers. So if you intend for our reader to replace a different reader model, we always recommend that you send us a sample tag that we can test for compatibility.

Can the PlugNGo™ Long Range RFID Reader work with existing 3M/Sirit 4100 tags?

Yes, see above: the PlugNGo™ Long Range RFID reader was designed to read open standard 26-bit Wiegand tags. It was designed to be compatible with the latest generation of Sirit credentials, provided that there isn’t any strange proprietary encoding from your distributor.

It’s a bummer that production on the 3M 4100 reader, once the gold standard of RFID readers, has been discontinued. You can’t buy a new one when those devices fail … and service is costly and can take weeks. Or you can replace them with the trusty PlugNGo™ Long Range RFID reader which works with your existing system effortlessly. Don’t leave the gate open for weeks while you get your reader serviced; plug in a PlugNGo™ Long Range RFID reader!

What access control software can I use?

Whichever you’d like. The best software is the one you know how to use. As long as your software handles keycards, key fobs, or any other 26-bit Wiegand RFID credentials, setting it up to read HeadlightStickers™ will be simple. Contact [email protected] if you’re not sure whether HeadlightSticker™ will work with your system.

We are also able to offer software options.

Confirmed compatibility includes AMAG, Door King, HID, Kantech, Keyscan, Keri, Liftmaster, Lenel, Linear, S2 Security, and Software House. Using something else? Ask us about your software and we’ll double check for you.

About Vehicular RFID

Why are HeadlightStickers™ ineffective upon removal? What if someone peels it off?

“Ineffective upon removal” is a powerful security feature. Read here for more.

Access sharing is the most common preventable method of unauthorized access. Of course some end users will miss being able to transfer their access credential between multiple vehicles. But they will also appreciate the peace of mind in knowing that a bad guy can’t steal the tag from their headlight to gain access to their home or workplace.

We recommend always keeping a few extra stickers on hand for quick resolution in case a user needs it for a new vehicle, or if a sticker is stolen.

The sticker is designed to break upon removal, thereby rendering it ineffective. Don’t worry – it’s easy to remove the leftover sticker.

What about windshield RFID transponders? Keycards?

We have windshield RFID tags, hangtags, side mirror tags, keycards, and more!

Fair warning. Generally speaking, windshield tags are a little more error prone than HeadlightStickers™. That’s because the glass presents a barrier for the signal. In most cases this forces installers to mount the readers above the vehicle lane to be parallel with the sticker. HeadlightSticker™ system allows you to mount the reader much closer to the ground… not so much “in the driver’s face.”

Also consider that many vehicles with metallized windshields interfere with the signal transmission no matter how you position the reader.

Keycards and hangtags work in a similar manner, but beware: they can be shared with people you don’t know about. They are also prone to user-error. If that’s alright, usually keycards have a pretty reliable 20 foot success range with our PlugNGo™ Extended Long Range RFID reader, but this can be improved or diminished by factors such as angle of the card, or how the card is held.

What about vehicles with a high amount of radio frequency interference?

Some vehicles have features that create a lot of wireless interference, especially driver-less cars. The PlugNGo™ Long Range RFID reader is better equipped to successfully read tags on such vehicles, due to its ability to adjust its sensitivity settings on the spot. But we do have some larger in-grill transponders available if your customers have concerns.

In a market saturated with low-end RFID tags, how is your price point justified?

HeadlightSticker™ transponders are purpose-built, high end products with very high success rates and great durability. The ultra-light design eliminates issues like light blocking or heat absorption, while the powerful adhesive and durable polymer extend the expected lifespan by years.
