A standalone fingerprint door access device is usually enough for a single door in an office, clinic or shop. It verifies a fingerprint, card or PIN and releases the electric lock directly, with no PC or separate controller. When you have several doors, or need central management, permissions and one event log, you move to a networked access controller.
This guide explains how to choose a fingerprint and card device for one door from the models AZEIDK carries, including the ZKTeco F34 Lite, X100/X101 and MK2, what you need alongside it (lock, power supply, exit button), and when a standalone unit is no longer the right answer.
Key takeaways
- A standalone device combines the reader, the controller and the lock relay in one housing. It suits one door, or a few separate doors.
- Fingerprint capacity varies widely: 500 templates on the ZKTeco X100/X101 versus 3,000 on the F34 Lite, according to AZEIDK’s product pages.
- The MK2-V/MK2-H works with card and PIN only, without fingerprint.
- The device alone is not enough: each door needs a suitable electric lock, a power supply, an exit button and, ideally, a door sensor.
- With several doors or a need for central network management, a controller such as the Hikvision DS-K2801 with an external reader is the better fit.

What is a standalone fingerprint door access device?
A conventional access control system has three parts: a reader at the door, a controller inside the building that grants or denies access, and an electric lock that carries out the decision. A standalone device puts the reader and the controller in one unit mounted beside the door. It stores users, fingerprints and cards in its own memory and has a lock output plus inputs for an exit button and a door sensor.
The benefit is simpler installation with fewer components, and it keeps working without a network. The trade-off is that basic models are managed one by one: adding an employee or cancelling a card is done at each door, unless the device supports network or cloud management.
For the technical difference between a standalone unit and a controller, and how each is wired, see Access Controller Wiring: Reader, Maglock, Exit Button, Door Contact and Fire Alarm Lock Release.
Fingerprint, card, PIN or face?
Fingerprint
It cannot be forgotten or lent, which suits offices and clinics that want to stop staff sharing cards. Check the device’s fingerprint capacity, and remember that some users have fingerprints that read poorly because of their work or dry skin. Devices therefore usually support a fallback such as a card or PIN.
Card
Faster in daily use and better for large numbers of users and visitors. Two types are common: 125 kHz ID (proximity) cards and 13.56 MHz IC cards such as Mifare. In a published IPVM test, most 125 kHz formats were unencrypted and could be copied with an inexpensive cloner, while the same tool could not copy encrypted 13.56 MHz formats such as DESFire. Encrypted 13.56 MHz cards are therefore the better choice for doors that need higher security. Whatever you choose, the cards must match the reader’s frequency.
PIN
Useful as a fallback or for a door used by very few people, but weak on its own because codes are easily shared. It works best combined with a fingerprint or card (dual verification) on sensitive rooms.
Face recognition
Touchless and suited to busy entrances. AZEIDK also carries face terminals such as the ZKTeco FaceDepot-7B and Hikvision DS-K1T320EFWX, but this guide focuses on fingerprint and card devices. For a fuller comparison of the technologies, see Time Attendance Devices: Choosing Fingerprint, Face or Card; many of these terminals do both jobs.
Fingerprint and card door devices available from AZEIDK
The values below come from AZEIDK’s product pages and, for the F34 Lite, from ZKTeco’s official product page. Always confirm them in the datasheet for the version supplied before approval.
| Model | Verification | Users / fingerprints / cards | Card type | Communication | Protection |
|---|---|---|---|---|---|
| ZKTeco F34 Lite | Fingerprint / card / PIN, 2.4-inch colour screen | 3,000 / 3,000 / 3,000, plus 200,000 transactions | 125 kHz ID standard, 13.56 MHz IC optional | TCP/IP, Wiegand, RS485, USB; Wi-Fi and PoE optional | IP65 |
| ZKTeco X100 / X101 | Fingerprint / card / PIN | 10,500 / 500 / 10,000 | 125 kHz ID standard, 13.56 MHz IC optional | Wiegand in and out (26–44 bit) | IP66, indoor and outdoor |
| ZKTeco MK2-V / MK2-H | Card / PIN (no fingerprint) | 10,000 /, / 10,000 | 125 kHz ID | Wiegand in and out | IP66, zinc-alloy housing |
| Dahua ASI1212F / ASI1212F-D | Card / PIN / fingerprint / remote, 2.8-inch touch screen | 30,000 / 3,000 / 30,000, plus 150,000 records | 13.56 MHz IC (ASI1212F), 125 kHz ID (ASI1212F-D) | 10/100 network, Wi-Fi, RS-485, Wiegand | Not stated on the product page |
AZEIDK’s page notes that Dahua has discontinued the ASI1212F, so ask for the current equivalent before ordering. The X100 and X101 differ only in dimensions, as do the MK2-V and MK2-H.
How to choose a fingerprint door access device for your office
- How many people will enrol a fingerprint: above 500, the X100/X101 falls short for fingerprints; look at the F34 Lite or a higher-capacity unit.
- Where it will be mounted: an external door exposed to sun, dust and rain needs a high ingress rating. The X100 and MK2 are IP66 (AZEIDK’s X100 page lists it for indoor and outdoor use); the F34 Lite is IP65. AZEIDK’s pages list an operating range of -40 to 60 °C for the MK2 and -25 to 60 °C for the X100.
- How you will manage it: to add and remove users from a phone or from one location, choose a networked device. According to ZKTeco, the F34 Lite works with the ZKBio Zlink cloud platform (web portal and mobile app) by default, or with ZKBio CVAccess and ZKBio Time on premises.
- Time attendance: if the device will also record working hours, check that it supports attendance software. The F34 Lite works with ZKBio Time.
- Reading on exit: to verify on the way out as well, choose a device that accepts a second reader. AZEIDK’s pages state that the X100 and MK2 can act as a master unit with a Wiegand sub-reader, or as a sub-reader for another controller.
What else do you need to install it?
The device is only one part of the door. Each door typically needs:
- An electric lock suited to the door: a magnetic lock (maglock) is common on glass, timber and metal doors and releases when power is removed. An electric strike may be fail-safe or fail-secure depending on the model, so check its datasheet.
- A power supply sized for the device and the lock together. AZEIDK’s pages list the F34 Lite at 12 V DC 1.5 A and the X100 and MK2 at 12 V DC 0.15 A; add the lock current from its own datasheet.
- An exit button to open the door from inside without a fingerprint. The F34 Lite, X100 and MK2 pages list an exit button input; the Dahua ASI1212F page does not mention one, so check its datasheet.
- A door sensor to show whether the door was left open or forced. The F34 Lite, X100 and MK2 support it.
- Cards or key fobs on the frequency the device reads.
Power sizing and common wiring mistakes are covered in detail in the access controller wiring guide.
What about emergency exit doors?
If the door is part of an escape route, the lock must not stop people leaving during a fire or a power failure. The Saudi Building Code and Civil Defense requirements for the project govern this, and the designer checks them case by case. Common practice, as AZEIDK’s access controller wiring article explains, is to use a lock that releases on power loss on these doors, and to cut the lock supply directly from the fire alarm panel on alarm rather than through the device’s software. Where the building has a fire alarm system, coordinate the door release with it before installation.
When is a standalone device not enough?
A standalone unit works well up to a point. A controller with an external reader becomes the better choice when:
- There are several doors and you want to manage permissions from one software package rather than device by device.
- The external door needs higher security. In a standalone unit the lock relay sits inside the device beside the door. Mounted on the outside, the lock-release circuit is closer to anyone tampering with it. With a controller, only the reader is outside; the controller and lock wiring stay within the protected area.
- You need time and zone permissions, such as allowing one department in at set hours only.
- You need one log and reports across all doors for security or HR.
| Criterion | Standalone device (e.g. F34 Lite or X100) | Controller + reader (e.g. DS-K2801 + ASR2101A-ME) |
|---|---|---|
| Typical number of doors | One, or a few separate doors | One door up to many doors within one system |
| Where the release logic sits | In the device at the door | In the controller inside the protected area |
| Management | On the device, or via network/cloud on supporting models | Over the network with management software |
| Installation | Simpler, fewer components | More cabling and upfront design |
Examples AZEIDK carries include the Hikvision DS-K2801 controller for one door, with two Wiegand ports for entry and exit readers, a dry-contact lock relay, exit button and door sensor inputs, and TCP/IP; its page lists 10,000 cards and 50,000 records for the product series. A suitable reader is the Dahua ASR2101A-ME, which reads 13.56 MHz Mifare and 125 kHz ID cards, connects over RS-485 or Wiegand, and does not work on its own. AZEIDK also lists the Dahua ASI1202M fingerprint and card controller; its page notes that the model is discontinued and that the current equivalent can be recommended on request.
Common mistakes when buying a fingerprint door device
- Buying cards on a frequency the device cannot read, such as 13.56 MHz cards for a 125 kHz-only reader.
- Choosing a fingerprint capacity below the real headcount plus expected growth.
- Mounting an indoor-only device on a door exposed to sun and rain.
- Undersizing the power supply, so the device reboots or the lock does not hold.
- Relying on a PIN alone for a sensitive door.
- Fitting a lock that does not release on power loss on an emergency exit door.
- Buying a standalone device for every door in a multi-door building and struggling to manage them later.
Access control from AZEIDK

FAQ
What is the best fingerprint door lock device for a small office?
There is no single best device. For a small team the X100/X101 (up to 500 fingerprints) may be enough; if you want network or app management and 3,000 fingerprints, the F34 Lite is the better fit.
Does a fingerprint door device work without internet?
Yes. A standalone device stores users locally and releases the lock without a network. The network or cloud is only for remote management and downloading logs.
What is the difference between a door access device and a time attendance terminal?
A door device controls the lock and supports an exit button and door sensor; an attendance terminal records working hours. Some devices, such as the F34 Lite, do both.
Do I need a magnetic lock with a card door device?
You need an electric lock of some kind. A maglock is common; an electric strike is an alternative depending on the door and frame. On emergency exits, choose one that does not block egress.
When should I move to a central controller?
When you have several doors, need time-based permissions and one log, or want the lock-release logic inside the protected area rather than at the external door.
Conclusion
A standalone fingerprint door device is a practical choice for one door if it has enough fingerprint capacity, the right card type and an ingress rating that suits its location, and if the lock, power supply and exit button are right. As the building grows or security needs rise, a controller with an external reader is the next step.
