Salto, a global pioneer in smart access solutions, launches 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.

Operating on a 100% wire-free architecture, it delivers maximum security without the complexities of a traditional wired setup. It retrofits seamlessly over existing door preparations and mortise locks, streamlining deployment while minimising installation time and costs.

Electronic locking solution

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.

When access needs are bidirectional, security on both sides of the door becomes an essential operational need. The XS4 double-sided reader and electronic lock provide a modern, wire-free solution, enabling controlled entry and exit via smart credentials presented on either side. This configuration is ideal for gates, shared access points, and secure zones requiring two-way access control and management.

Unauthorised credential sharing

Key features include:

  • Anti-passback management. XS4 Double Reader smart locks can control two separate anti-passback areas, to track entry and exit sequences and prevent unauthorised credential sharing
  • Occupancy and roll-call tracking. Monitors user location relative to defined zones, recording the exact date and time of every entry and exit event
  • Access point consolidation. Cuts back access control hardware requirements at each access point to a single solution
  • Advanced security. Ensures doors are always locked from both the inside and outside
  • Aesthetic versatility. Combines the modern square profile of the XS4 One S with sleek reader surfaces, alongside the iconic construction of the XS4 Original+
  • Ease of installation. Designed for simplicity and versatility, is quick and easy to install or retrofit on most standard doors
  • Compatibility and integration. Fully compatible with the Salto BLUEnet Wireless infrastructure, facilitating real-time management and seamless integration with Salto's best-in-class access control platforms: Salto Space, Salto KS, and Salto Homelok
  • Keyless experience. Delivers a highly secure, completely keyless experience for users, supporting a wide range of digital credentials, including RFID, mobile digital keys, or room key in Apple Wallet
