Do you need to remove data?
While old card payment machines may store a record of data on the device, modern card readers from the likes of SumUp and Zettle do not.
An app-based card reader just reads and encrypts the card data electronically in a format usable by the associated app. No data is stored in the hardware, so you do not need to destroy it before disposal.
The same applies to standalone card terminals like Square Terminal or PAX A920 because they process data online in an encrypted format, not locally on the terminal. You only need to log out of the account you logged into on the terminal, before it is handed to someone else.
Old, traditional card machines with push-buttons – manufactured by e.g. Ingenico, Verifone or Spire – may have some record of past transactions that needs to be destroyed before disposal. We recommend contacting the manufacturer about this, unless your terminal provider has given you other instructions.
