The tamper detection system includes tamper detection devices such as tamper switches or tamper meshes, and tamper detection circuitry to control and interface with the tamper detection devices. Pulses are selectively provided from each of a plurality of tamper signal pins of the tamper detection circuitry to an associated tamper detection device, the outputs of the tamper detection devices are multiplexed, the multiplexed signal is received at a tamper detection pin, and a tamper attempt is identified if a pulse was not received within the multiplexed signal. While not transmitting, each of the tamper signal pins is switched to an input state, and a tamper attempt is also identified if any aberrant signal is received at the tamper signal pins while in the input state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiplexed tamper detection system","description":"A payment reader includes a tamper detection system for monitoring and protecting against attempts to tamper with the payment reader.
