1. A method performed by a computing system for detecting a potentially malfunctioning payment card reader, comprising:
receiving, at the computing system from a first mobile computing device, information indicating whether or not a payment card was read by a first payment card reader during payment transactions; receiving, at the computing system from a second mobile computing device, information indicating whether or not a payment card was read by a second payment card reader during payment transactions; identifying, at the computing system, payments made by reading payment cards as card-present (CP) payment transactions and payments made without reading payment cards as card-not-present (CNP) payment transactions, wherein CP payment transactions occur by payment card readers automatically reading data encoded at payment cards and CNP payment transactions occur by collecting manually entered payment card information without automatically reading data encoded at payment cards; monitoring, at the computing system, a ratio of CP to CNP transactions at each of the first and the second mobile computing devices; determining, at the computing system based at least in part on the monitored ratios, which of the first or the second card readers or the first or the second mobile computing devices is malfunctioning; and causing a remediation action, wherein the remediation action is at least one of sending a replacement card reader or transmitting a communication. |
