# Connect an eSSL or ZKTeco biometric attendance machine > Point an eSSL or ZKTeco fingerprint or card machine at Pathshala so every punch lands on the staff register — or upload its Excel, or use a card reader. Source: https://pathshala.mjxtechnologies.com/docs/people/biometric-devices/ With MJX Attendance Pro, an eSSL or ZKTeco machine — fingerprint or ID-card swipe — sends every punch to the staff register by itself. In Pathshala, the first punch of the day becomes the check-in and the last the check-out. Door access devices from eSSL / ZKTeco work the same way. > [!PATH] Apps › MJX Attendance › Fingerprint / card machine ![Staff attendance screen with the Fingerprint / card machine card marked](media/people/biometric-devices-1.jpg "Attendance › Staff › Fingerprint / card machine") ![Fingerprint / card machine screen — point the machine at Pathshala — with the Add machine button marked](media/people/biometric-devices-2.jpg "Apps › MJX Attendance › Fingerprint / card machine") At a school, open **Attendance › Staff** and the **Fingerprint / card machine** card. ## Steps to connect a machine (push to Pathshala) 1. On the machine, open **Menu → Comm. → Cloud Server Setting** (called **ADMS** on some models). 2. Set: | Setting | Value | |---|---| | Server address | Your organisation's own address, shown on the screen — for example `sunrise.pathshala.mjxtechnologies.com` | | Port | 80 | | Domain name | ON | | HTTPS | OFF (unless the machine offers it) | 3. Find the machine's serial number: **Menu → System Info → Device Info**. 4. In Pathshala, under **1 · Point the machine at Pathshala**, type the **Serial number** and a name (for example *Front door*), and press [[Add machine]]. > [!SUCCESS] > Within a few minutes the machine shows a "last seen" time, and new punches appear under **Latest punches**. ## Steps to match people to machine numbers Under **2 · Who is which number on the machine**: 1. For each person, type the number they were enrolled with on the machine (**User ID**) — the same number whether they use a finger or a card. 2. Press [[Save]]. **Numbers the machine sent that nobody is matched to yet** are listed, so you can see who is still missing. Punches that arrived before a number was matched are applied the moment you match it. ## How to upload another machine's Excel Under **Another machine? Upload its Excel**: 1. Export the attendance log from the machine's software as Excel or CSV. It needs a **User ID** column (or Emp Code / PIN) and a **Date Time** column (or **Date** and **Time**). 2. Choose the file and press [[Upload]]. Punches already here are skipped. ## No machine? A card reader at the desk Under **No machine? A card reader at the desk**: 1. Plug in a USB card reader — sold as "RFID USB reader, keyboard mode" — on the office computer or a tablet. 2. Type a name (for example *Front desk*) and press [[Add a check-in screen]]. 3. Copy the link ([[Copy]]) and open it on the desk computer or tablet. Press F11 for full screen and keep it open. 4. Everybody taps their ID card once when they arrive and once when they leave. The screen says **Tap your card**. > [!WARNING] > The link is shown only once. Anyone with it can record taps for your office — keep it on that screen only. Lost it? Press [[New link]]; the old one stops working at once. **Android phone with NFC:** open the check-in screen's link in Chrome on the phone, press [[📱 Use this phone's NFC]] once, and people hold their card to the back of the phone. iPhones cannot do this in a browser. ### Give each person their card Under **Who has which card**: - Click a person's box and tap their card on the reader — the number types itself — then [[Save]]. - Or on an Android phone, press **📱** beside the person and hold their card to the phone. - Typing it? Use the chip's Serial Number as an NFC app shows it (for example `53:63:F3:…:40`), with the colons. Nothing is written on the card; its own chip number is used. Taps made before a card was given are put on the register when you save. ## For technicians: what the machine talks to The machine uses the standard push protocol. Pathshala answers in plain text and identifies the organisation by the machine's **serial number** (an unregistered serial writes nothing). | Request | Purpose | |---|---| | `GET /iclock/cdata?SN=` | The machine says hello and gets its settings (TimeZone=330) | | `POST /iclock/cdata?SN=&table=ATTLOG` | Attendance punches, one line per punch: `PIN YYYY-MM-DD HH:MM:SS …` | | `POST /iclock/cdata?SN=&table=rtlog` | Door controller events — only "door opened for a person" counts; refused entries and alarms are ignored | | `GET /iclock/getrequest`, `POST /iclock/devicecmd` | Answered `OK` | ## Who can use it? Owner, Admin, or anyone with **Manage Check-in Machines** (the **HR** job has it). The feature is **MJX Attendance Pro**. A check-in screen on an organisation without it says *"Card check-in is not switched on — It comes with MJX Attendance Pro — ask the office."* ## Common messages | Message | What to do | |---|---| | Type the machine's serial number exactly as its menu shows it (letters and numbers). | Copy it from Device Info | | That machine is already added. | It is on your list already | | That serial number is registered to another organisation. If it is yours, ask MJX. | Contact MJX support | | Number … is already somebody else's on the machine. | Each User ID belongs to one person | | Could not find the columns… | The file needs a User ID and a Date Time (or Date and Time) column | | This check-in screen's link is not valid | Make a new link on **Fingerprint / card machine** | ## Questions people ask ### Does the fingerprint leave the machine? No. The fingerprint and the card stay on the machine. It sends only the person's number and the time. ### Which punch is the check-in? The first punch of the day is the check-in, and the last is the check-out. Every way of punching — finger, card, face, phone — counts together. ### My machine is not eSSL or ZKTeco. Can I still use it? Yes. Export the attendance log from the machine's software as Excel or CSV and upload it under **Another machine? Upload its Excel**. ### What if punches arrive before I match a person's number? They are kept, and applied the moment you match that number to a person. ### Can I use ID cards without a machine? Yes. Plug a USB card reader into a desk computer or tablet and open a check-in screen, or use an Android phone with NFC.
