uPASS Go is a passive UHF RFID reader that identifies vehicles at an access point from up to 10 metres (33 ft). It reads EPC Gen 2 tags through the windscreen, so the driver does not stop, does not open a window and does not present a card. The barrier opens while the vehicle is still approaching.
Nedap has been building vehicle access control for more than 30 years. Our readers protect over 100,000 gates and authorise more than 10 million vehicles. uPASS Go brings that to entrances with a basic gate layout and a tight budget.
uPASS Go is the successor to the uPASS Reach
If you are looking for the uPASS Reach: it has been replaced by uPASS Go. The reader keeps the same job in the portfolio, long-range vehicle identification at access points, and adds an adjustable read range, EPC Gen 2 tag support, OSDP v2 with secure channel communication, a USB-C service interface and a redesigned mounting bracket.
Existing installations do not have to be rewired. uPASS Go still speaks Wiegand, so it can take the place of a uPASS Reach on the cabling that is already in the ground.
What determines the read range
The 10 metre figure is a maximum, not a guarantee. Three things decide what you get in practice: the tag you choose, how the reader is mounted and the environment around the access point (metal structures, other RF sources, vehicle height).
The tag is the biggest single factor. These are the ranges Nedap publishes for uPASS Go per tag:
| Tag | Read range with uPASS Go | Typical placement |
|---|---|---|
| UHF Windshield Tag | up to 10 m (33 ft) | Inside of the windscreen |
| UHF Hangtag | up to 10 m (33 ft) | Rear-view mirror, reusable |
| UHF Heavy Duty Tag | up to 10 m (33 ft) | Bolted to a metal vehicle part |
| UHF Exterior Tag | up to 8 m (26 ft) | Headlight or other non-metallic part |
| UHF Card | up to 7 m (23 ft) | Carried in the vehicle |
The read range is adjustable, so you can tune it down at a narrow entrance where you only want to read the vehicle in front of the barrier and not the one in the next lane.
Wondering how uPASS Go compares to the uPASS Target, which reads up to approximately 15 m? See passive UHF solutions for the full portfolio, or use the product advisor.
Any tag orientation, first time
uPASS Go uses a circularly polarised antenna. A tag is read whatever angle it sits at, so a windscreen tag stuck slightly crooked or a hangtag swinging from a mirror is still picked up on the first pass.
That matters more than it sounds. A missed first read is what makes a driver stop, reverse and try again, and one stopped vehicle at 08:15 backs up everything behind it. Circular polarisation removes the most common reason for that second attempt. See optimize traffic flow and avoid delays at the entrance.
Fits the access control system you already run
uPASS Go connects over Wiegand, RS485, Ethernet 10/100 Mbps and USB-C for service. Outputs are Wiegand and magstripe (clock and data). On the protocol side it supports OSDP v2 with secure channel communication, TCP/IP, CR/LF and a range of OEM protocols.
Two consequences worth knowing:
- Retrofit without new cabling. Wiegand runs up to 150 m on 22 AWG, so in most existing installations the reader goes straight onto the wiring that is there.
- Encrypted reader communication where policy demands it. OSDP v2 secure channel protects the link between reader and controller, which is increasingly a hard requirement in tenders for government sites and campuses.
The reader also provides a relay output (1x NO/common/NC, 24 VDC 2 A), a read disable input and three general purpose TTL inputs.
Air interface and region. ISO 18000-6C and EPC Gen 2, 865 to 928 MHz depending on region. uPASS Go is ordered per regulatory region (ETSI, FCC, AU, NZ, MY, PH, MA), so specify the country of installation when you request a quote.
Installation and service
A pole mount set is included in the box and fits round poles up to 133 mm and square poles up to 100 mm. For wall or ceiling mounting there is an optional mount set extension with adjustable angles, and for entrances in direct sun there is an optional weather protection hood.
Once the reader is on the pole, a service hatch and a USB-C service interface give access to the online configuration interface without taking the unit down. A built-in buzzer and LED confirm a read on site, which makes commissioning and fault finding a two-minute job instead of a laptop session. A magnetic tamper switch (normally closed) reports interference with the housing.
Built for the entrance, not for the server room
uPASS Go is rated IP66 (NEMA 4x) and runs from -30 to +60 degrees Celsius at 10 to 93 percent non-condensing humidity. The housing is UL-rated ASA+PC. It sits outdoors, unsheltered, through winter and through summer, which is exactly where an access point is.
Where uPASS Go is used
Business premises and staff parking. The load is concentrated: most of the day is quiet and then several hundred vehicles arrive inside forty minutes. Hands-free identification keeps that queue moving without adding a second lane or a barrier attendant.
Gated communities. Residents get in without lowering a window in the rain. Because the tag is bound to a vehicle rather than to a person, a shared entrance stays controlled without a gatehouse.
Public services and university campuses. Large populations, high turnover of permits, several entrances. A tag per authorised vehicle is cheaper to administer than a card per person, and OSDP v2 secure channel meets the security requirements that public tenders tend to specify.
Car parks and gated business parks. Season ticket holders and long-term contract parkers pass without touching anything, while visitors are handled through the existing ticket or intercom lane.

Frequently asked questions
What is the read range of uPASS Go?
Up to 10 metres (33 ft) in combination with the UHF Windshield Tag. The range you achieve depends on the tag, the installation and the environment. With a UHF Exterior Tag it is up to 8 m, with a UHF Card up to 7 m. The range is adjustable, so it can be tuned down for narrow lanes.
What happened to the uPASS Reach?
The uPASS Reach has been replaced by uPASS Go. uPASS Go covers the same use case and adds an adjustable read range, EPC Gen 2 tag support, OSDP v2 secure channel, a USB-C service interface and a new mounting bracket. It works on existing Wiegand cabling.
Which tags work with uPASS Go?
Any EPC Gen 2 (ISO 18000-6C) tag. Within the Nedap portfolio that is the UHF Windshield Tag, UHF Hangtag, UHF Heavy Duty Tag, UHF Exterior Tag and the UHF Cards, including combi cards that also carry Mifare, DESFire, Legic advant, HID Prox or HID iCLASS for door access.
Does uPASS Go work with my access control system?
In most cases yes. uPASS Go supports Wiegand, RS485, Ethernet and USB-C, and speaks OSDP v2, TCP/IP, CR/LF and a range of OEM protocols. Wiegand output makes it a direct replacement in existing installations.
Can uPASS Go be installed outdoors?
Yes. It is rated IP66 (NEMA 4x) and operates from -30 to +60 degrees Celsius. For entrances in direct sun a weather protection hood is available.
What is the difference between uPASS Go and uPASS Target?
uPASS Go is the cost-effective reader for basic gate layouts, with a read range up to 10 m. The uPASS Target reads up to approximately 15 m and is aimed at entrances where more range or more control over the read field is needed.
Is uPASS Go available in my country?
uPASS Go is certified for multiple regulatory regions (ETSI, FCC, AU, NZ, MY, PH, MA). State the country of installation when you request purchase information, so the right variant is quoted.
