Topic summary

A user seeks recommendations for credit card machines to sell jewelry and watches at festivals in Louisiana, USA.

Primary Recommendation:

  • Shopify’s Tap and Chip Reader is suggested as the best option for US-based sellers
  • Connects directly to Shopify Payments for quick setup and seamless integration
  • Transaction fees match the user’s Shopify subscription plan rates

Alternative Options:

  • Third-party readers (like Square) are possible but require:
    • Separate account with that service
    • Custom payment method setup in Shopify
    • Additional transaction fees on top of the third party’s processing fees
    • Manual transaction recording in Shopify POS

Key Limitations:

  • Existing terminals (Verifone Vx520, V400M) cannot be reprogrammed for Shopify Payments
  • These devices are locked to their original payment processors
  • Third-party readers can still be used but won’t integrate directly with Shopify’s system

Status: The discussion remains open with a new inquiry about Verifone V400M compatibility unanswered.

Hey there, @EdG10 . Thanks for jumping in on the thread!

You are able to use a third party card reader alongside Shopify POS to facilitate transactions. However, as third party readers aren’t directly supported by Shopify POS, the way it would work is that you would facilitate that transaction with your third party reader, which would be using a third party payment gateway. Then, you would keep a record of that transaction within Shopify POS. We have a help document here that goes over that information.

Essentially, using a supported, Shopify Card Reader allows everything to integrate very smoothly, and with Shopify’s in-house payment processor, Shopify Payments. You won’t be able to ‘reprogram’ the third party reader to integrate with Shopify Payments, but it is still equipment that you can use to facilitate transactions.
