Description
Proximity Reader with Mobile Credentials designed for modern access control systems. The NODER MDB-R and NODER MDKB-R readers combine secure RFID, NFC® and Bluetooth® mobile credentials with an ultra-slim 1.5 cm profile. Forget about compromising between advanced technology and aesthetics. Our readers provide reliable, contactless access while blending seamlessly into any environment. Designed for places where every detail matters. We believe that security systems do not have to be conspicuous or disrupt a carefully planned interior design. Thanks to extensive customisation options, you have complete freedom to create a cohesive look for your space. Whether you want the device to harmonise perfectly with your chosen electrical fittings or to blend discreetly into the colour of the wall or façade, this reader will adapt to your vision. You receive a bespoke solution in which reliable functionality goes hand in hand with impeccable design. The reader’s front panel is manufactured using technology that prevents unsightly fingerprints and ensures the device retains its pristine appearance even with heavy use.
As truly multi-technology readers, the MDB-R and MDKB-R work as a smartphone access reader, an NFC and Bluetooth access reader, and a traditional contactless access reader for MIFARE cards — all in one secure device.
Our proximity reader with mobile credentials supports the latest identification standards, including MIFARE DESFire technology and mobile technologies. It guarantees full data protection thanks to encrypted RS485 communication (AES256).
Its compact dimensions and modern design allow for hassle-free installation on most standard profiles and door frames, whilst its IP54 rating ensures resistance to dust and splashes. As a result, the MDB-R is ideal not only for prestigious lobbies and offices, but also for areas with high humidity or high levels of dust. Whether you need a mobile credential reader, an RFID reader with mobile access, or a classic card-based solution, readers cover every credential type your organisation uses today — making it one of the most secure access control readers on the market.
This reader allows you to
When used with the NODER Mobile Access app and the NODER Virtual Access Card, the mobile access reader enables authorisation directly from iOS- and Android-based smartphones. This solution makes it possible to reduce, or even completely eliminate, the need to issue and carry traditional, physical RFID cards.
Are you wondering whether this is a secure solution? Be sure to read the article “Virtual cards versus physical cards: Mobile credentials in NODER access control”.
The reader was designed and manufactured entirely in European Union.
The reader uses advanced encryption at every stage of communication:
- when exchanging data with controllers,
- when reading physical MIFARE DESFire cards,
- when connecting to the NODER mobile Virtual Access Card.
The housing of the MDB-R and MDKB-R readers are the same and is made from high-quality ASA (Acrylonitrile-Styrene-Acrylate) plastic. This is an advanced engineering polymer which, in terms of mechanical properties, is similar to the widely used ABS, but significantly outperforms it in terms of resistance to external factors.

FAQ
Is a mobile credential reader as secure as a traditional card reader?
Yes — and in most cases more secure. The MDB-R/MDKB-R encrypts every stage of communication: AES-128 for physical MIFARE® DESFire® cards, AES-128 for virtual Bluetooth®/NFC® credentials, and AES-256 for RS-485 communication with the controller. Unlike static card credentials, mobile credentials via the NODER Mobile Access app can be instantly revoked or reissued remotely if a phone is lost or an employee leaves — something a physical card cannot do on its own.
Can this reader work as both a smartphone access reader and a classic card reader at the same time?
Yes. The MDB-R/MDKB-R is a genuine multi-technology reader: it accepts MIFARE Classic® and MIFARE® DESFire® cards, NFC® smartphone credentials, and Bluetooth® credentials simultaneously, with no need to choose one technology over another. This makes it a practical migration option — you can roll out mobile credentials gradually while existing card holders keep using their current cards.
What's the difference between the MDB-R and MDKB-R models?
Both are the same NFC and Bluetooth® mobile access reader with identical encryption and technical specifications. The MDKB-R additionally includes a keypad for PIN entry, enabling two-factor authentication (card/phone + PIN) for areas requiring a higher security level.
What's the difference between the MDB-R and the MD-R models?
Both readers support MIFARE Classic® and MIFARE® DESFire® cards with AES encryption. The key difference is mobile support: the MDB-R adds NFC® and Bluetooth® smartphone credentials through the NODER Mobile Access app, while the MD-R is a wired-only RS-485 reader without mobile capability. If your access control system doesn't need mobile credentials, the MD-R is a more cost-effective option.
Should I choose the MDB-R/MDKB-R or a wired reader like the MD-R or MD-W?
Choose the MDB-R/MDKB-R if you want to support mobile credentials (NFC® and Bluetooth® via smartphone) alongside or instead of physical cards — it's the right choice for organisations moving toward mobile-first access control, or that want the flexibility to issue credentials remotely. If you only need traditional card-based access with no mobile component, the MD-R (RS-485) or MD-W (Wiegand) are simpler, lower-cost alternatives with the same MIFARE® DESFire® security level, differing only in the wired communication interface.
Does the reader require an internet connection for mobile credentials to work?
No. Once a mobile credential is issued through the NODER Mobile Access app, authentication happens locally via NFC® or Bluetooth® directly between the phone and the reader — no internet connection is required at the door for day-to-day access.
Is this rfid reader with mobile access compatible with existing NODER access control systems?
Yes. The MDB-R/MDKB-R is fully compatible with NODER's EWE4, EWE4-LCD and EE12 controllers, and can be combined on the same system with other NODER readers (MD-R, MDK-R, RCP-1) — you don't need to replace your entire installation to add mobile credentials.
Can I use this reader outdoors?
Yes, in the (z) housing variant, which is rated IP65 for resistance to dust and water splashes. The indoor (w) variant is rated IP51. Both variants also feature ASA plastic housing that resists UV degradation, impact, and common cleaning chemicals.
Do I need a separate app or license for each user to issue a mobile credential?
The NODER Mobile Access app is free to download on iOS® and Android™. However, each Virtual Access Card (mobile credential) requires a per-user subscription license, ordered separately from the app itself — see Mobile Credentials by NODER Mobile Access for full details on how subscriptions work.
Can I mix MDB-R readers with MD-R or MD-W readers in the same installation?
Yes. All NODER readers — MDB-R, MDKB-R, MD-R, MD-W and MDK-R — are fully compatible with the same NODER controllers (EWE4, EWE4-LCD, EE12) and can be combined freely within a single system. This lets you deploy mobile credential readers at high-traffic entrances while keeping simpler wired readers at secondary doors, without needing separate systems.
