Which term is the initial point of data reading from a card in a payment transaction?

Explanation:
The initial point where card data is read in a payment transaction is the Point of Interaction. This term refers to the device or terminal at the merchant that first captures the card’s data (swipe, dip, or contactless) and inputs it into the payment flow. The PIN Block is the encrypted PIN data used during authorization, not the moment the card data is read. Personal Firewall Software protects networks, not the data capture step, and POP3 is just an email protocol, not related to card data in a payment flow. So, the Point of Interaction is the correct concept.
