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.

I would recommend first familiarizing yourself with the program Access by watching introductions.

In a mailbox based message passing system, a process is not put in a waiting queue but receives an error signal upon sending to
Daniel [21]

Answer:

Yes.

Explanation:

Race condition can be described as a situation where at any time there are two or more processes or threads operating concurrently, there is potential for a particularly difficult class of problems. The identifying characteristic of race conditions is that the performance varies depending on which process or thread executes their instructions before the other one, and this becomes a problem when the program runs correctly in some instances and incorrectly in others. Race conditions are notoriously difficult to debug, because they are unpredictable, unrepeatable, and may not exhibit themselves for years.
