Using a wireless technology known as Near-field communication (NFC), once activated on the smartphone, allows payments or purchases to be made at select stores.

<h3>What is Near-field communication (NFC)?</h3>

NFC is a set of short-range wireless technologies that typically require a distance of 4 cm or less to initiate a connection.

<h3>Characteristics of Near-field communication (NFC)</h3>

  • For it to work, it is necessary to place two spiral-type antennas within these close electromagnetic fields.

  • This technology is built on radio frequency identification, which allows a gadget to send radio waves to another gadget or another tag and trigger a certain action.

  • The NFC acts on the smartphones just like the RFID chips of the bank cards with which you can make payments or purchases.

Therefore, we can conclude that the NFC allows two devices to exchange data when in close proximity to each other.

Why were american colonists unhappy with king george iii?
nalin [4]
The colonists were unhappy with the British monarch because the British parliament would pass acts, such as taxing the colonists on certain things (tea, stamps), without any representation for the colonists. Parliament passed acts such as the Coercive Acts<span>, called the Intolerable Acts by the colonists, which angered the colonists and made them strive for independence. </span>

Novosadov [1.4K]

Incomplete question. The full question read;

Why is Jim having these problems?

Options:

A. Security scanners are not designed to do testing through a firewall.

B. Security scanners cannot perform vulnerability linkage.

C. Security scanners are only as smart as their database and cannot find unpublished vulnerabilities.

D. All of the above.

Answer:

<u>D. All of the above.</u>

Explanation:

<em>Remember, </em><u>security scanners</u> are only designed to <em>gather</em> information about a network, but not with the ability to perform firewall testing. Also, these security scanners are pre-programmed with existing vulnerabilities in their database, and so it would impossible to discover vulnerabilities on the Retail store's network.

Hence, since Bob is using the wrong tools, he is unsuccessful in performing a penetration test.

How does the actual amount left to spend differ from the budgeted amount for the remaining three months of the project?
Vlad [161]

Answer:

The left(in actual) can be more or less than the budgeted for the remaining time. Suppose some resource fell ill or got damaged, you are going to invest in them, and get them back. However, for that, you need to spend money, and this reduces the actual left, as more of the budgeted is being spent. And this is the difference between the two, the actual left to spend from the budgeted for the remaining time of the project. However, the project managers keep an extra budget these days for such a situation, and hence this drawback in the project plan has already been removed, and the problem is solved.

Explanation:

Please check the answer.

The overexpense %

= (( Actual spent - Budgeted amount)/Budgeted amount) *100
