Why does the vending machine reject cash?

How does a vending machine work?

Unlike the way to identify coins which you only need to distinguish based on the size and weight. For banknotes, vending machines must be integrated with modern technologies to be able to read money and identify two factors: real or fake money; The value of the bill.

Checking and identifying money is an important responsibility for a vending machine. Therefore, this invoice validation department needs to work closely and thoroughly.

History of Invoice Validation

Invoice validation has been around since the 1960s when a part of Mars (where famous candies like M&M, Mars,.... are produced) created technology that used magnetic heads to read magnetic ink that printed on the bill. This technology helps the vending machine read and work well with the information printed on the currency.

The technology of invoice validation is improving day by day which improves the accuracy of the validation. The machine uses a photoelectric cell to detect different shades of the money's ink, reads the difference on the bill’s ink, determines if it is real or fake, and how much it is worth.

However, over time the device can get dusty, unable to read the bill, or if your money is wrinkled or blurred, the vending machine will reject it.

When does the vending machine reject cash?

The bill is dirty

During the transaction, your money may get dusty, oily, or unwanted stains. Along with that, vending machines that have been used for many years will accumulate dirt on the validator, preventing the photoelectric cell from reading your bill. Therefore, if the money is dirty, it will be difficult for the vending machine to read the denomination, so your money will be rejected.

The bill is torn, crumpled

To make sure the vending machine receives money quickly, your bill needs to be straight, not torn, wet or crumpled. A clean and flat bill will make it easier for the machine to check if your money is real and determine the correct denomination of the bill.

Customers not choose goods before buying

Before putting the bill into the machine, customers need to choose the product to buy. Therefore, if there is a problem that the machine refuses to receive money, think of the case that the customer has not yet selected the goods.

Invoice validation worn out

This validation is a series of small parts in the machine. Over time, these devices will wear out, and especially the belt clip that holds and pulls money through. At that time, the machine will not accept the bill and refuse the transaction.

It can be seen that the vending machine rejects bill issue may come from the customer's side, it may also be due to the machine's fault. Therefore, in order for the machine to operate smoothly and to minimize this problem, entrepreneurs need to have the best machine care and maintenance regime; regularly check and add change money to the machine so that all bills can be received at any time.
