Question

technology connection
for many years, workers punched a time - card into a
time - clock to check in and out. some companies now
use hand scanning technology. an employee’s hand becomes the
person’s time - card. reader machines identify each person by the
size and shape of a hand. how might these machines improve
security?

Explanation:

To answer the question about how hand - scanning machines improve security:

1. Uniqueness of Hand Features: Each person's hand has a unique size and shape. Unlike a time - card which can be stolen, lost, or shared, a person's hand is an inherent and unique identifier. So, it is very difficult for an unauthorized person to mimic another person's hand size and shape to gain access or clock in/out fraudulently.
2. Reduced Fraud Opportunities: With time - cards, there is a risk of "buddy punching" (where one employee clocks in or out for another). Since hand - scanning requires the actual presence of the employee's hand, this type of fraud is eliminated. Also, time - cards can be forged, but forging a hand's size and shape is extremely challenging.
3. Enhanced Accountability: Since the hand - scanning system is linked to a specific individual's unique hand characteristics, it becomes easier to track who is clocking in and out. This increases the accountability of employees as they know that their hand is associated with their time - related activities, reducing the likelihood of time - theft or other security - related violations.

Answer:

Hand - scanning machines improve security in the following ways:

• Each person’s hand size and shape is unique, making it hard for unauthorized individuals to mimic another’s hand to clock in/out or gain access (unlike time - cards which can be stolen, lost, or shared).
• It eliminates “buddy punching” (where one employee clocks in/out for another) as the actual employee’s hand is required.
• It enhances accountability as the system is linked to an individual’s unique hand characteristics, reducing time - theft and related security violations.
