Swipe (30 Pin) Card Reader discontinued
Shopify has discontinued the Swipe (30 Pin) Card reader.
The Swipe (30 Pin) reader was designed to be used with iPhone 4/4S and iPad 2/3. With changes to the supported devices and iOS versions for Shopify POS, the reader no longer meets our performance standards.
If you're using the reader, then you can continue to do so. We recommend that you upgrade to a device that supports iOS 10 or above and a supported card reader from the Shopify Hardware Store.
