A POS device with fingerprint authentication such as the TPS900 integrates payment, identity verification, and printing in one unit. It supports Android-based operation, up to 4GB RAM + 64GB ROM, optional fingerprint module, and multiple payment channels including NFC, QR, and card reading. The device runs on 4G/Wi-Fi/Bluetooth connectivity and is designed for continuous retail and service usage environments. The Telpo EFT POS line is positioned around an integrated payment architecture rather than a single-function terminal. The TPS900 unit is built with a 5.5-inch HD display and runs on Android OS, supporting application-level deployment for retail checkout and service counters. Its hardware setup includes an octa-core processor and memory combinations starting from 2GB RAM + 16GB ROM and extending to 4GB RAM + 64GB ROM. These configurations support parallel transaction processing and application switching without external modules.
The device integrates multiple payment input channels including magnetic stripe cards, IC cards, NFC, QR code scanning, and optional fingerprint verification. This structure removes the need for separate authentication terminals in point-of-sale environments.
In retail usage scenarios recorded by Telpo product documentation, the system is designed to operate under continuous daily workload conditions. The battery system supports up to 15 hours of working time and up to 12 days standby duration, with 3000mAh standard and 4400mAh optional battery configurations. These values align with mobile cashier environments where charging access is limited during shifts of 8–12 hours per day. The transition from traditional POS hardware to a pos machine with fingerprint scanner changes how identity checks are placed inside payment flows. Instead of separate biometric readers, the TPS900 integrates an optional fingerprint module certified for financial-grade identity verification environments. This module is used in workflows where customer identity confirmation is required before transaction completion, especially in banking onboarding and regulated service counters. Connectivity layers inside the device include 4G, Wi-Fi, and Bluetooth Low Energy 5.0. In distributed retail environments, this allows transaction data to sync without fixed network infrastructure. The device also supports dual SIM configurations in certain builds, improving network continuity when a single carrier signal drops below usable levels.
In field deployment setups, integrated connectivity reduces the need for external routers or tethering devices, especially in mobile payment operations such as delivery-based retail or outdoor service stations.
The printing system is integrated into the same chassis. The thermal printer supports 80mm/s printing speed and 40mm paper width, with a printing durability rating above 100km. This eliminates external receipt printers in compact checkout environments and reduces cable-based peripheral setups. From a security standpoint, the terminal follows PCI and EMV compliance requirements, supporting Mastercard PayPass and Visa PayWave standards. The fingerprint module operates as an optional layer above standard PIN and card verification, adding a second authentication channel when enabled. Memory and system performance scaling is designed for different transaction volumes. Lower configurations handle basic retail checkout workflows, while higher configurations (4GB + 64GB) are used for environments running inventory, reporting, or loyalty applications on the same device.
The combination of Android OS, octa-core processing, and multi-channel payment input allows the device to function as both a transaction terminal and a lightweight business management unit.
In deployment environments where transaction frequency exceeds 200–300 operations per day, the integration of biometric verification reduces manual ID checks that would otherwise require separate staff input steps. This reduces hardware switching across devices during customer service flows. Battery and portability design also supports outdoor or semi-mobile setups. With 15-hour runtime capacity, the device can cover a full work shift without mid-day charging interruptions. In multi-terminal retail setups, this reduces dependency on fixed cashier stations. The overall architecture of the TPS900 positions it as a unified payment and verification system rather than a single-purpose POS device. The integration of fingerprint authentication, multi-network connectivity, and embedded printing reduces peripheral dependency in service environments where space and speed constraints are present.
