How does RTC clock work?
An RTC maintains its clock by counting the cycles of an oscillator – usually an external 32.768kHz crystal oscillator circuit, an internal capacitor based oscillator, or even an embedded quartz crystal. Some can detect transitions and count the periodicity of an input that may be connected.
What is RTC payment?
An RTC transaction is an interbank electronic credit payment instruction issued by the payer to the paying bank to transfer funds from the account of the payer to the account of a beneficiary, which payment instruction is delivered by the paying bank to the credit of the beneficiary account within 60 seconds.
What is real time bank transfer?
A real-time payments system is composed of technology that enables instantaneous money transfer between banks and banking systems. Credit and debit card transactions go through a bank settlement process that can take up to 72 hours to clear and settle.
Why do we need a real time clock ( RTC )?
An RTC is battery powered and keeps track of the current time even when there is no power. Real Time Clock ICs are present in computers, servers, many embedded systems and in fact they are used wherever it is required to keep an accurate time.

Which is the best real time clock module?
The Real Time Clock is an affordable module. You can check the DS1307 Real Time Clock module on Maker Advisor and find the best price. Wiring the RTC module is pretty straightforward!
How to connect the RTC module to the Arduino?
Connect your Real Time Clock module to your Arduino as in the schematics below. Working with the RTC requires two important steps: retaining the time, so that the RTC always gives the correct time, even when it is turned off For setting the current time you need to change the code provided.
Why are RTC modules used in a computer?
RTC modules are used because they make it easier to keep accurate time. They do this by maintaining time when the system is shut down or rebooted (by way of a battery or some other mechanism for keeping running independently of the host system) and by providing a time base that is, usually, more accurate than that of the host.
