1. What is the figure print template size?
Max 1K bytes, average 300 bytes, depends on the fingerprint image.
2. Is the fingerprint template that is stored in the ACTAtek encrypted?
When a finger is scanned, the complete image is stored and encrypted for protection. In addition, the template is encrypted, as it can be stored on the user's local disk or smart card instead of being stored on the device. So the user's privacy is preserved.
3. Limitation of current fingerprint recognition technologies?
- Maximum Auto-match for 500 people because not inputting any ID is very cumbersome for the system since it needs to search the entire database to locate 1 particular fingerprint template.
- There are bound to be workers whose fingerprint cannot be recognised due to the nature of the work causing very dry or chaffed finger.
So the best scenario is to do the following:
- Reserve auto-match for your most senior executives;
- Others key in their ID and authenticated by fingerprint OR PASSWORD; or use a smart card to gain entrance WITHOUT ANY FORM OF AUTHENTICATION during rush hour by just flashing the card. When they leave work, present the card which stored the fingerprint and authenticate with fingerprint OR PASSWORD. As leaving work is not as urgent as going to work in the morning.
- If employees have unusually dry or chapped fingers, it is advisable for them to rub their finger against their nose or use moisturizing lotion before enrollment for better image capture.
4. Can ACTAtek support dirty fingers?
Dirty fingers are an issue for ALL biometric devices since they reduce performance. However, ACTAtek still offers various ways to overcome dirty fingers, such as:
- Try NOT to use the Automatch feature since that will require the person to have very high fingerprint quality during authentication. This will cause dirty fingers to be rejected since the quality of the image may be affected severely.
- On the web browser, you can reduce the personal security levels for specific employees who have dirty fingers and whose images are difficult to read by the scanner.
5. What should be done if the ACTAtek FP Sensor's autoscan shows the message "Bad Quality"??
Clean the grease of the FP Sensor with tissue frequently.
