ESSL K30 Access Control Time Attendance

There was a time when fingerprint scanners were a thing of science fiction. As a child, we used to see these hi-tech devices only in movies.

I would like to point though the time has changed now. Technology to manufacturer fingerprint readers has improved and become a lot cheaper in the last few years. As a result, many offices have started using biometric attendance machines that use employees fingerprint scan to register their attendance.

If you have not installed a biometric attendance machine at your office then I strongly suggest doing it. This machine will not only make employees more conscious about timings but also help you manage their attendance record easily. Below is a list of three affordable attendance machines that we have compiled after two weeks of research.

Easy To Setup

Setting up the MDI machine requires no expert knowledge. This can be done in the following simple steps:

  1. Connect the device to a power outlet using the adapter and then press the power button.
  2. Press the menu button and then select the Employee option.
  3. On the next screen select the first option i.e. Register
  4. Now fill all the details of the employee including ID, Name, and Department.
  5. In the last step, the employee needs to put his or her finger on the glass scanner three times.
  6. Repeat these steps for registering all employees

Compact Body

This device does not require a lot of space on the wall. It comes in a compact body and feels appealing to the eyes. Quality of the build materials though is not good.

Power cord is long, which means customers can install the MDI machine at the location of their choice without any kind of restriction.

Also Supports Password

In addition to fingerprints, employees also get the option to register their attendance using a password. Although this feature is a bit controversial (because it paves a way for proxy records), it will help an employee in case fingerprint scanner module shows some error.

Good Connectivity Options

On the left side, this machine features a full-size USB port and a miniUSB port. It can store up to 1,00,000 attendance records and register up to 10,000 employees. Users can transfer the onboard records anytime using a thumb drive.


  • Audio notification system
  • Good onboard storage
  • Attractive body
  • Highly affordable
  • Color display


  • Build quality is not good


For those who are a looking for an affordable solution, there cannot be a better option than the MDI-3600 Biometric Time & Attendance machine. However, you should also consider its bad build quality before making a purchase decision.

High Quality Fingerprint Reader

The onboard fingerprint reader is really good at its job. It reads and processes fingerprints within no time. Moreover, the chance of returning an error is also very less.

Realtime has loaded this machine with a feature-packed operating system. A single person can register multiple fingers to be on the safer side. Only the admin user will have access to the menu and settings of the OS.

Come With A Bunch Of Features

Customers can also use the Relatime Attendance machine with EM cards to give door access to employees. The list of connectivity features includes Wi-Fi, USB port, and Ethernet jack. It is capable of communicating with a server using the internet.

The manufacturer offers optional features like GPRS connectivity and battery backup at additional cost.

Bad Post-Purchase Support

Although this machine is impressive in terms of features and functionality, you may still want to look for some other product. Realtime gives the worst customer service after the purchase. In fact, the manufacturer does not provide telephonic support and warranty to people who have purchased this machine online.

The instruction manual Realtime sends with the machine is not written properly, thus, many readers  find difficulty in follow that. A person with no prior knowledge of biometric machines will struggle to use it.


  • Good design
  • 8-inch screen
  • Wi-Fi and Ethernet
  • EM card support
  • Fast and responsive interface


  • No warranty on online purchase


On the front of functionality, this machine manages to get a good score. My main concern, however, is of customer support. I would recommend readers to purchase the Realtime Attendance machine only if you can find it in a local store.

ESSL K30 Attendance Biometric Security Device

The last on this list is the ESSL K30 Attendance Machine. Available with a price tag of 6,400 rupees, the machine is the best biometric attendance recorder for small offices.

Accurate And Fast

A 500 dpi fingerprint scanner sits on the right side of the front panel and processes scans in milliseconds. It offers high level of accuracy every time you punch a finger.

Like most biometric attendance machines of this price segment, the ESSL K30 also features an RFID card sensor. The onboard storage can record 80,000 logs before requiring a reset. Other features of this machine include schedule bell, self-service query, and SSR recorder.

Inbuilt Battery

The most interesting fact about this ESSL product is it sports an inbuilt battery. It can work in case of power outages without any problem. There is also an Ethernet port on the back for connecting a server.

Unattractive Design

In terms of looks, this device has failed to attract us. The manufacturer has used low-quality materials while making it.

The display is backlit but its viewing angles are not wide. Thus, be sure to install it a height where employees would have no problem in reading the screen.


  • Inbuilt battery
  • Schedule bell
  • 80,000 logs
  • Highly accuracy
  • Access control


  • Unpleasant looks


Except design and build, everything else on the ESSL machine seems to be good. It will not create any problem during the usage. The features this device comes packed with are hard to come by.
