Payment gateway technology used by merchants to accept bank or credit card purchases from customers. This term includes not only the card-reading devices found in brick and mortar stores but also the payment processing facilities available at online stores. However, brick and mortar payment methods in recent years have begun to accept telephone payments using Near Field Communication (NFC) technology.
- Payment methods are consumer-oriented areas used to collect payments.
- In physical stores, payment gateways containing sales terminals (POS) are used to accept payments by card or telephone.
- In online stores, payment gateways are "exit" areas used to enter credit card details or service guarantees such as PayPal.
