Today, we are announcing the launch of the new Salto XS4 Double Reader wire-free, smart locking range. This solution features two integrated readers within a single electronic smart lock, a unique configuration that enables facilities to monitor and record both entry and exit at a single door.

Designed for high-level functionality, global compatibility, and aesthetic versatility, the XS4 Double Reader is a compact yet powerful universal electronic locking solution that redefines what modern access control can look and feel like, all while facilitating security and operations.
Unlocking smart, bidirectional control
When access is bidirectional, security on both sides of the door becomes an essential operational need. The XS4 double-sided readers and electronic locks provide a modern, wire-free solution, enabling controlled entry and exit with smart credentials on either side.
This configuration is ideal for gates, shared access points, and secure zones requiring two-way access control and management.
Key features include:
- Anti-passback management. In standalone mode, XS4 Double Reader smart locks can control two separate anti-passback areas, enhancing the capabilities of the Salto Virtual Network (SVN) data-on–card technology and users ID-based smart access rules management functionality. An online mode is also available through the system network, empowering operators to track entry and exit sequences and prevent unauthorized credential sharing.
- Occupancy and roll-call tracking. The system monitors users' locations relative to defined zones, recording the exact date and time of every entry and exit event. This smart security feature is designed to restrict access to certain areas or resources within a space or building. With this function, operators can immediately generate real-time presence lists that limit the number of people allowed in a specific area at any given time, essential for safety auditing and muster reporting.
- Access point consolidation. By managing bidirectional traffic tracking within a single door footprint, the XS4 Double Reader range cuts back the access control hardware requirements at each access point to a single solution, all consolidated within one smart double-locking solution. This significantly reduces the number of components required while slashing installation time at the door. muster reporting.
