NFC, or Near Field Communication, is a technology that allows devices to communicate wirelessly when they are placed in close proximity to each other. This technology is often used for things like contactless payments, where a customer can simply tap to open a web page on their smartphone or payment card against a payment terminal to complete a transaction.

To take contactless payments using NFC, a merchant will need a payment terminal that is equipped with NFC capabilities. These payment terminals typically have a designated area, called a "touchpoint," where the customer can tap their NFC-enabled device to initiate the payment.

Here are the general steps for taking a contactless payment using NFC:

1. A Spring connected product is always 'turned on' as it uses a passive chip and ready to accept payments.
2. Place the Spring in a visible and accessible location, so that customers can easily see it and reach it.
3. When a customer is ready to make a payment, they should hold their NFC-enabled device near the touchpoint.
4. The customer should then tap to open a page in the browser of their device to initiate the payment.
5. The customer will then process the payment on the phone through card, Apple Pay or Android Pay and, if successful, will provide a confirmation to the customer via email or SMS and the merchant.
