Posiflex SA105100 MSR Attachment 3-Track Encryption USB

Overview

The Posiflex SA105100 is a 3-track magnetic stripe reader (MSR) attachment designed for point-of-sale and payment processing environments. It connects via USB and includes on-device encryption — meaning card data is encrypted at the reader before transmission, reducing the scope of PCI-DSS compliance on downstream systems. This model ships without a fingerprint reader, making it a cost-effective fit for general payment processors that don't require biometric credential storage.

Compatibility

The SA105100 integrates with Posiflex payment terminals and general POS systems that accept USB MSR peripherals. Confirm your terminal's USB input and MSR driver support before ordering. Encryption capability requires the endpoint system to recognize encrypted stripe data — verify firmware compatibility with your payment processor or terminal vendor.

Installation Notes

Connection is USB plug-and-play; no separate power supply required. The encryption feature operates passively — no additional configuration needed once the device is recognized by the host system. Position the reader for operator access without exposing the magnetic track to dust or liquids; IP ratings are not specified for this attachment, so avoid splash zones and high-moisture areas. Test stripe reading with a known-good card before deployment to confirm driver recognition and encryption handshake.
