How do contactless smart transport cards work?
The card and the reader communicate by using radio wave via wireless communication.
The card operates from electromagnetic energy received from the reader.
To pay the fare, riders simply must hold their cards up to the readers and the fare will be deducted from the card’s balance.
These contactless smart transport cards contain many layers of security, hence, making it almost impossible for others to counterfeit and use them.
This made payment of bus and train fare faster, easier and more convenient.

Mobile Payments
Mobile payment systems store credit and debit card information and allow consumers to pay for in-store purchases with those cards.
To make payment, the consumers do not need to have their wallet with them, they just need to take out their mobile phone and hold it a few inches away from the point of sale terminal.
The mobile payments system relies on near-field communication technology to rapidly transmit data during in-store payments.
Application: Shopping
Mobile payment
The terminal will read the payment information stored in the smart chip embedded in your card then processes the payment.
The point of sale terminals emits a high frequency radio wave that facilitates communication between the terminal and the mobile device.
When the mobile devices are placed near the terminals, a wireless communication protocol links them and exchange information and conduct the transaction.
Some of the most popular NFC payment applications include apple pay, which is a contactless payment technology for Apple devices and google pay, which is a contactless payment technology for all non-rooted Android devices.
