Detecting debris in payment card readers

Abstract

Various exemplary devices, systems, and methods for detecting debris in payment card readers are provided. In general, a card reader configured to read a card for payment and/or other purpose(s) includes a slot configured to receive the card therein. In an exemplary embodiment, a tester is configured to be inserted into the card reader slot and identify whether debris is present in the slot that would prevent the card reader from properly reading data from a card inserted into the slot, e.g., from reading a chip of the card, etc. The tester is configured to be inserted into the card reader slot with the card reader on site at its installed location, e.g., as part of a fuel dispenser or other payment terminal.
