BTB Pay 1.3.2

OAO "Bai Tushum" presents its product for fast contactless payments, BTB Pay. This offering is built on NFC technology, appealing primarily to those who wish to stay current with modern payment solutions and conduct swift, contactless transactions.

NFC, or "near field communication," is a short-range wireless data transmission technology that facilitates data exchange between devices. A significant factor concerning the security of NFC payments is the operational distance, which ranges around 100 mm or even less. Consequently, smartphones must be held very close to the terminal, making interception of the signal nearly impossible.

The data exchanged via NFC is encrypted and protected by the same EMV standards as chip cards. Each time a transaction is initiated, a one-time key is generated upon the terminal's request, ensuring it is valid only for that specific transaction. Additional protection is provided by payment limits set by banks in accordance with payment system recommendations. In Kyrgyzstan, the payment limit is currently 1000 COM, though some acquiring banks offer payments up to 4000 COM without requiring a PIN code. If a transaction exceeds this limit, the terminal prompts for PIN confirmation.
