picopass operates with the ISO 14443B proximity protocol for high-speed communication at a range of 10 centimeters. Applications include POS and biometric identification. It uses the vicinity protocol ISO 15693 to operate at lower speeds over longer ranges:
- 1.5 meters in gate antenna configuration
• 70 centimeters with a single antenna. Standard yields higher communication speeds at proximity distance.
The longer-range capability is suited to applications like asset tracking or hands-free access.
