Fingerprint bio-metric scanning is one of the most modern and used way on recognizing a person’s identity. This technology was vastly used from person identification, registration, crime investigation, attendance and up to the simplest form like opening your smart phone.

As for Able Bioplus, one of the most recognized product in time and attendance, Fingerprint bio-metric devices are used to record clock in and clock out of employees. With this, time theft and inaccuracy in payroll making are lessen to none.

Fingerprint scanning works great and should work great in the most perfect sense in a perfect world but of course, we are not living in a perfect world. Listed down are the common issues in fingerprint scanning

  1. Fingerprints are used up and there is no visible marks.
  2. Its taking ages for a fingerprint to be recognized.
  3. Worst case scenario is, The finger that was used in fingerprint scanning is missing, We won’t be discussing on how or why it is missing (no pun intended here).

Defective scanner is one of the culprit in some cases, But most of the time it is the finger that causes the problem. 2 main fingers are mostly used in fingerprint recognition and those are the thumb and the pointer. Below are the common injuries with these fingers that can be the cause of bio-metric scanning issues

  1. Paper cuts. Employees tend to use thumb to scan through or shift pages of papers may it be loose or not. In this practice, paper cuts are a common result wherein a person can injure the fingerprint than can induce a new line or mark which the fingerprint scanner cannot read due to the fact that the original fingerprint template doesn’t contain that new line. This new line can be temporary or permanent depending on how sever the case is.
  2. Fingerprint are so used up. Fingerprint are part of the skin, Everybody knows that the skin can be damaged and can peel. Due to excessive usage of fingers, the marks can be faded overtime specially for employees who are working in construction, carpentry and cleaning with chemicals. Doing these tedious jobs means that there are too much force and friction that can lead to temporary fading of fingerprint. Thumb and pointer are the usual finger used for an activity while the rest of the fingers are used as a guard for grip. Thumb and pointer are the ones that uses force and friction to hold unto things so there are more chances on damaging the fingerprint.

The arguments presented above are mostly affecting employees on temporary basis, but this  affect the attendance and the pay. In these cases what can be done to prevent or at least to lessen this? Everybody will agree on enrolling multiple fingers of course but the unsung hero here is the pinky finger.

Some will say “why? “, some will raise their eyebrows and some tech people will say “your freaking kidding me mate?”. We’ll actually pinky is the most unused finger there is, We are not saying it is useless but it is most likely be the finger that has a perfect and complete fingerprint. People don’t put force or friction to this finger as it is really inconvenient for handling pressure and work. With this in mind, it is actually a best candidate for fingerprint recognizing.

In some reading, it is actually recommended that for security purposes pinky should be used in fingerprint bio-metric access due to the fact that most determined person that tries to bypass the security will opt on getting the thumb and pointer templates as it is more convenient to use for most people. With pinkie finger, it will be harder to detect due to convenience issue.

So the next time an employee is having a hard time in clocking in and out due to fingerprint issue,  enroll the pinky finger it saves the day… mostly.
