The
Telpo T20 is a transport-grade ticket validation terminal built for outdoor use in public mobility environments. It uses a 7-inch anti-glare touchscreen with 500cd/m² brightness and supports both open-loop and closed-loop payment systems in one unit. It processes ISO14443 Type A/B, Mifare, Cipurse, Calypso, Felica cards, EMV Contactless L1 bank cards, QR codes, e-wallet payments, and paper tickets in a single workflow. The system is designed with IP65 protection and IK08 impact resistance, allowing continuous use in exposed environments such as bus platforms and station gates. It also includes 8 SAM card slots and dual system support (Telpo OS based on Android 12 and optional Linux), giving operators flexibility in integration and deployment.
“A single validation point reduces switching between devices, which directly shortens boarding time in high-frequency passenger environments.”
When operational environments involve mixed payment formats, hardware fragmentation becomes a constraint. The Telpo T20 merges multiple validation methods into one interface, so passengers do not need different terminals for card, QR, or mobile payments. In transport deployments reported in 2025 field usage documentation, mixed-mode validation systems like this reduce average transaction steps by more than 30% compared with single-format devices, especially in rush-hour boarding cycles above 1,000 passengers per hour.
The device architecture also supports continuous network synchronization through 4G, dual-band Wi-Fi, and Bluetooth, while GPS provides location-based transaction tagging. Optional external antennas extend signal stability in low coverage zones, which is important for rural or long-route bus systems. In parallel, MDM remote management allows operators to monitor distributed terminals across multiple routes without physical access, reducing on-site maintenance frequency in large fleets operating over 50 vehicles or more.
“Connectivity stability matters most when terminals operate across routes with uneven network coverage.”
Durability is another factor affecting operational continuity. The IP65 rating ensures full dust resistance and water jet protection, while IK08 certification allows resistance against impact in public access areas. These specifications are relevant in outdoor installations where devices face continuous physical contact and weather exposure. Compared with indoor-grade terminals (often IP54 or lower), IP65-class devices are typically deployed in environments where annual downtime needs to remain under 2% to maintain service continuity targets in transport systems.
The Telpo T20 integrates a high-speed 2D barcode scanner supporting QR and Aztec formats with hardware-level decoding. This reduces validation delay when passengers present tickets from mobile screens or printed formats. The scanning module is optimized for mixed lighting conditions, which aligns with the 500cd/m² display output, keeping readability consistent in daylight exposure zones such as open bus terminals.
“Fast decoding is not about single scans, it is about handling mixed ticket sources without user adjustment.”
Security capacity is expanded through 8 SAM card slots, allowing multiple cryptographic modules to operate in parallel for fare validation, identity verification, and system authentication layers. In large transit deployments, this setup supports integration with multi-operator fare systems where different transport agencies share infrastructure. The design also leaves room for future protocol expansion without hardware replacement cycles.
A technical integration layer is supported through dual OS selection. Telpo OS based on Android 12 provides application-level flexibility, while Linux support enables deeper system embedding into legacy transport platforms. Operators in multi-system environments often use Linux builds when connecting to existing ticketing backends that were developed before 2020, reducing redevelopment requirements during system upgrades.
The device also includes audio feedback for passenger confirmation, which is important in noisy environments such as bus boarding zones or metro entrances. Sound-based confirmation reduces the need for visual checking, especially during peak boarding periods when passenger flow exceeds 600–800 persons per lane per hour.
“Audio feedback reduces hesitation time between scan and movement in crowded boarding lines.”
Installation is supported through a pole-mounted structure with a lockable enclosure. This design simplifies deployment across large fleets, reducing installation time per unit when scaling to 100+ terminals across a transport network. The enclosure also reduces unauthorized access risk in unattended public locations.
