Electronic funds transfer at point of sale (EFTPOS /ËÉftpÉs/) is an electronic payment system involving electronic funds transfers based on the use of payment cards, such as debit or credit cards, at payment terminals located at points of sale.

Definition - What does Overloading mean? Overloading refers to the ability to use a single identifier to define multiple methods of a class that differ in their input and output parameters. Overloaded methods are generally used when they conceptually execute the same task but with a slightly different set of parameters.
Overload means an excess current drawn, which will lead to tripping of the circuit breaker once the current exceeds 5 times the rated MCB current value within a tenth of a second (depending on the Type of MCB). When your electric load is faulty and there's a short circuit, a lot of current is drawn -> MCB trips. But an electric shock to a human being may not always draw an excessive current that is so high to trip the MCB and protect you. This is where RCCB comes in.
