The plain one, and often the right one.
A 2.8-inch screen, a touch keypad, QR and card. The least terminal that still controls a door and records the attendance in the same moment, which on a side entrance or a store room is exactly the amount of terminal wanted.
Q8Q8 QR Code & RFID Reader Access Control
What this one is good at
Does the two things
Releases the lock and records the punch, in one action, into the same record everything else reads. The rest of this page is about what it does not have.
QR and card
Card QR codes, visitor QR codes and server-minted codes, plus ID cards as standard with IC cards as an option. A touch keypad behind both for a PIN.
A million events on board
The local log holds a million records and 100,000 credentials. Take the network away for a week and nothing is lost; it catches up when the network returns.
Wiegand in and out
It can sit in front of an access controller you already own, reading credentials and passing them on, rather than replacing a working panel.
Cheapest way to cover a door
On a site with one main entrance and four secondary ones, this is what goes on the four. Same records, same live view, a fraction of the terminal.
USB stick in and out
Users in and logs out on a USB stick, up to 100,000 records, for a door with no network at all. Not the way to run a site, but it means an awkward outbuilding is still countable.
With Attendance
The door happens, and it is in the software.
This is not a terminal you buy and then find an export routine for. It is integrated with Attendance at attendance.cy, and a punch at this door is in the live view before the person has finished walking through it.
Real time, not a poll interval
The gateway holds an open stream and pushes every event the instant it happens. No refresh, no five-minute wait, no "last synced at". Somebody checks in and the board has them.
Three layers, so nothing is lost
The push is the fast path. Behind it Attendance polls on a watermark with a five-minute overlap, and behind that the terminal keeps its own log: up to a million events. Cut the network for a week and every punch still arrives, carrying the time it was made.
Straight into hours, not a spreadsheet
The punch becomes a shift, the shift becomes hours, and the hours become an approved payroll batch: in one record, with the corrections attached to it. Nothing is re-keyed and nothing is reconciled by memory at the end of the month.
You can see the terminal itself
Online or not, when it was last seen, and whether collection is current or overdue: per unit, in the portal. A terminal that quietly stops reporting is visible the same day rather than when somebody queries a missing shift.
Right for
- Secondary doors, store rooms and back entrances
- Covering many doors on one site without many terminals
- Sitting in front of an access panel that already works
- Doors with no network run, using USB transfer
Not right for
A main staff entrance at 07:00. A 2.8-inch screen and a deliberate scan per person is slow when forty people arrive together. Put a face terminal there and these on everything else.

Power and network
- Power over Ethernet
- Supported One cable to the door: data and power on the same run, with no socket needed beside the frame. Confirmed by the manufacturer: the datasheets in circulation predate it and list only the DC supply.
- Backup battery
- Available The terminal keeps reading and keeps recording through a power cut, so the punches either side of it are still one shift. Confirmed by the manufacturer: this model's datasheet does not carry the row.
- DC power
- DC 12V 2A For a run with no PoE at the other end of it.
- Network
- Ethernet (TCP/IP), Wi-Fi optional, USB type-A
- Data transfer
- USB 2.0 host: import and export by USB stick
Attendance integration
- Live updates
- Real time, pushed The gateway holds an open stream and sends each punch the moment it happens. Somebody walks through the door and the live view has them, without a refresh and without a poll interval to wait out.
- If the network drops
- Nothing is lost The terminal keeps its own log, and Attendance polls the gateway on a watermark with a five-minute overlap. Reconnect and every punch made in the gap is imported, with its original time, not the time it arrived.
- Duplicate protection
- One punch, once The same event arriving by both push and poll is recognised as one punch, not two.
- Device health
- Online, last seen, collection state Shown per terminal in the portal, so a unit that has quietly stopped reporting is visible before somebody notices a missing shift.
- Verification status
- Integrated Integrated and carrying punches. It does not have the recorded seven-check certification the two face terminals do, and we would rather say so than blur it.

Q9The terminal is the part you can change your mind about.
Every one of these writes into the same record, so a site can run two models on two doors, or replace one in three years, without anything downstream noticing. What you are choosing here is how people get through a particular door, not a platform.
