Telpo T20 works as a transit ticket validation terminal designed for mixed payment environments. It supports ISO14443 Type A/B, Mifare, Cipurse, Calypso, Felica cards, plus EMV Contactless L1, PayWave, PayPass, QR, e-wallet, mobile payments, and paper tickets. It uses a 7-inch screen with 500cd/m² brightness and IP65 + IK08 protection, combining 4G, Wi-Fi, Bluetooth, GPS, and 8 SAM slots for secure fare systems. It is used in bus, rail, and gate control deployments. The Telpo T20 is positioned for transport operators running mixed fare systems where contactless and legacy ticket flows coexist in the same network. The device integrates open-loop and closed-loop payment support in one unit, reducing the need for separated validation hardware across different lines or service zones.
The payment layer includes ISO14443 Type A/B, Mifare, Cipurse, Calypso, Felica, EMV Contactless L1, PayWave, PayPass, QR code scanning, mobile wallets, and paper ticket verification within one terminal structure.
The display system is built around a 7-inch touchscreen rated at 500cd/m² brightness. This level supports outdoor readability under direct sunlight conditions where standard indoor terminals lose visibility. Anti-glare treatment is applied on the screen surface, allowing continuous interaction during passenger boarding peaks. The next layer is durability, where the enclosure follows IP65 dust and water protection combined with IK08 impact resistance. These parameters are used for outdoor transit points where equipment is exposed to rain, dust, and physical contact from passenger flow or environmental stress.
IP65 protection is defined for full dust sealing and resistance to water jets, while IK08 indicates resistance against mechanical impact in public-facing installations.
The hardware structure is designed around pole mounting, with a lockable enclosure that limits unauthorized access. This setup reduces exposure time during maintenance cycles and supports fixed installation in bus stops and station platforms. Communication systems include 4G, dual-band Wi-Fi, and Bluetooth. GPS is embedded for positioning support, allowing fleet-level synchronization with dispatch systems. External antennas can extend GNSS, 4G, 3G, and 2G reception in low-signal areas, especially for long-route bus corridors.
Module Specification
Display 7-inch, 500cd/m²
Protection IP65, IK08
Connectivity 4G, Wi-Fi, Bluetooth
Positioning GPS + external GNSS option
Security 8 SAM slots
The integration layer uses 8 SAM card slots, supporting cryptographic modules for transit security systems. This allows multiple operators or service domains to coexist within the same physical terminal without replacing hardware when system architecture changes.
The SAM architecture supports layered security processing for ticket authentication, payment validation, and system-level encryption functions.
On the software side, the Telpo T20 provides Telpo OS based on Android 12 and an optional Linux environment. Android is used for application deployment flexibility, while Linux is selected for tighter integration with existing ticketing systems in transport networks that rely on legacy backend structures.

Hardware decoding reduces processing load during peak boarding periods, where multiple passengers validate tickets within short time windows. Passenger feedback is handled through audio confirmation signals. These signals are used in noisy environments such as bus depots or station platforms, where visual confirmation alone is not sufficient for fast boarding flow. MDM-based remote management allows centralized monitoring of distributed terminals across multiple routes or cities. Configuration updates, system diagnostics, and deployment control are handled remotely, reducing on-site maintenance cycles across large fleets of devices.
