4id Solutions manufactures RFID and Bluetooth® LE smart labels and tags that support supply chain management across retail, logistics, manufacturing and healthcare. Each one begins with automated inlay testing and traceability logging, moves through on-demand digital printing for full-colour and variable data jobs, and comes together in RFID converting with automatic defect detection. Every order is backed by a certificate of conformance, turning static labels into dynamic tools that help track, trace and protect what counts.
