With Shopify, there's always an option for consumers to use most frequently accepted credit cards for completing a purchase on merchant's Shopify site. But Shopify also allows the merchants to utilize Shopify's POS system to accept credit card payments in the store in nearly every possible location. Using the Shopify card reader can help you in enjoying low rates (down to 2.4%) on all the transactions carried out on the eCommerce platform. With the POS, merchants can easily sync payment details with orders and offer clarity in the incoming revenue to merchants.
