Tips and Tricks


Congratulations on purchasing your ekey product! Your finger is now also your key! These little tips and tricks will help you to make the best possible use of your ekey finger scanners.


Installation position and mounting height

Installation position: Finding the right position for the finger scanner will make the finger swipe technique much easier to master and will improve finger recognition. The finger scanner works just as well whether you are right-handed or left-handed!

It is important to have enough moving space when standing in front of the finger scanner. Straining to reach the scanner will produce poor results.

Mounting height: The scanner can only be used ergonomically if it is mounted at the right height.

Minimum mounting height

Mounting the control panel

The control panel switches the relay and must, therefore, only be mounted in the protected internal area (tamper protection). It should, however, be easily accessible for programming purposes.


Finger swiping

A good finger swipe technique is crucial for optimal detection. The best method is to stretch out ALL of your fingers and place the finger to be scanned on the finger swipe area so that only the first phalanx is in contact with it. The joint of the first phalanx should be directly over the sensor.

Place the other fingers to the left and right of the scanner. Do not roll your finger onto the fingertip while swiping. Apply moderate pressure and swipe your finger evenly over the sensor at a medium speed: not too fast and not too slow. The incorrect amount of pressure will produce poor results.

The amount of pressure required will vary according to your skin type. Soft skin will require less pressure, dry skin will require more. Test a few different methods to see how you can achieve the best possible scan results for you. To begin with, the finger swipe technique takes a bit of practice. You will soon learn the best way to operate the scanner.


Sensor and finger surface

The sensor is the narrow strip across the bottom part of the finger swipe area. You must swipe the front phalanx fully over the sensor in order to achieve optimal results. The sensor must not be subjected to any mechanical stress other than operation with a finger and clearing with a soft cloth.

Do not scratch the sensor with your fingernail. Never clean the sensor with the rough side of a sponge or with any aggressive cleaning agents. Damaged sensors must be replaced.


Finger scan

From experience, the best fingers to use are as follows: 1. Middle finger, 2. Index finger, 3. Ring finger. The thumb and the little finger should not be used. Each person will have fingers that are more or less suitable for scanning. It is a good idea to use the hand you write with (right-handed/left-handed), as you will have more feeling in this hand. You should choose a clean finger without any cuts or grazes. If your finger has very few lines due to abrasion or for genetic reasons, it will not be detected by the sensor. Clearly visible lines will make it easier to recognize.

Children should use their index finger or whichever finger they instinctively choose to use. Use the fingers that are most comfortable for you and those that are recognized the quickest.


Saving fingerprints

To enable convenient operation with either hand, and as a backup in case of injury, you should enroll one finger from each hand. For fingers that are not so easy to scan – for example, those of small children, elderly people, or manual workers – the same finger should be enrolled in several storage spaces. There are 99 finger storage spaces available on the ekey home/ekey multi. It is generally better to enroll one finger several times rather than several fingers once. This increases the likelihood of detection and means that the system works better in the limit range of operation (dry fingers, skin cream or sweat after sport) or when operated under unfavorable conditions. With the single-relay variant, for example, you could simply use F1-F5 for the first finger and F6-F0 for the second finger on the same user storage space. This means that you will have 5 reference scans for each finger and will have used a total of 10 storage spaces.

Children's fingers: Children's fingers generally work from around school age. Using the multiple storage option described above, however, it is sometimes possible to enroll younger children's fingers too. The specified mounting height for IN 2.0, WM 2.0, and OM must be observed in order to ensure correct operation. If, when you swipe your finger over the sensor, the LEDs immediately turn red for a short period without flashing yellow first, this indicates that you have swiped your finger incorrectly or you have waited too long. You must swipe your finger downwards as soon as you place it on the sensor. The software interrupts the scan process and this is indicated by the LEDs briefly lighting up red.


Person 1 example:

  • Storage space 1, F3 for the left middle finger
  • Storage space 1, F8 for the right middle finger


It is a good idea to make a list of enrolled fingers if your control panel does not have a multi-line display.



Enrolling fingers and using the scanner is usually a straightforward process. However, if this information does not help you, please contact us:
