This coordinate describes a Czech retailer’s payment programme. It does not say Alza operates Bitcoin, provides custody or retains the BTC it receives.
Alza launched Bitcoin payments in May 2017. This is a checkout method for goods, not an exchange, wallet or part of the Bitcoin protocol.

Alza says five IT staff built the first integration in one week and 154 hours. Cryptocurrency-turnover figures are company claims, not independently audited results. [Alza — implementation infographic and first-month claims] [Alza mobile — first three weeks and attributed sales figures]
The order is priced in the shop currency; the gateway displays the rate, BTC amount, network fee and payment QR code. Rates and availability are gateway conditions.

An on-chain payment sends a Bitcoin transaction from the customer wallet. Its fee and confirmation time depend on the network and fee selection, not an Alza promise. [Alza — current Bitcoin, Lightning and crypto payment guide]
Alza added Lightning in early 2022. The gateway creates a Lightning invoice; fast confirmation does not guarantee a successful route or zero fee in every case. [Alza — current Bitcoin, Lightning and crypto payment guide] [Alza — Lightning payments launched in early 2022]
Confirmo intermediates between customer and Alza. Alza says processed bitcoin is converted into crowns or other fiat, so payment does not prove that Alza keeps BTC on its balance sheet.

The guide updated 3 July 2025 lists on-chain BTC, Lightning, ETH, USDT, USDC, SOL and TRX for Alza.cz, .sk, .de and .at. The menu may change. [Alza — current Bitcoin, Lightning and crypto payment guide]
GENERAL BYTES ATMs and cryptocurrency sales through PayBox are separate from paying an order. Exchanging cash, buying a coin and paying a merchant are distinct actions. [Alza — 2018 PayBox cryptocurrency sales] [GENERAL BYTES — May 2017 launch and showroom ATMs]
In 2020 Bitcoin payment at some pickup points was temporarily limited during a gateway API migration. Later guides show restoration, not uninterrupted availability. [e15 — temporary 2020 gateway API limitation]
The purchase contract, complaints and price refunds follow Alza terms. A blockchain transfer does not reverse itself; verify amount, network, address and current refund rules before sending.
