General Bytes, a Prague-based manufacturer of bitcoin ATMs and blockchain hardware, has introduced an NFC-enabled bitcoin wallet card designed to make crypto payments feel more like a tap-or-swipe transaction and less like a smartphone-based scanning process. The company’s goal is clear: replace the long-standing reliance on QR codes with a more seamless payment experience built around near field communication.
The product is part of a broader push by General Bytes to expand the practical usability of bitcoin in everyday commerce. Rather than asking users to unlock a phone, open a wallet app, and scan a code, the company envisions a workflow in which a customer simply uses a physical card with a compatible point-of-sale terminal. In the firm’s view, that kind of interaction can lower friction and make bitcoin spending easier for a broader audience.
A New Use Case for Bitcoin ATM Infrastructure
Founded in 2013, General Bytes is best known for building bitcoin automated teller machines and related cryptocurrency products. According to the company, it was among the first in the sector to integrate NFC technology into its devices. Its latest step is to combine ATM functionality with wallet issuance by enabling a machine to dispense NFC wallet cards that can hold bitcoin-related credentials.
The company said its BATMThree XXL+ model is the first ATM in the industry to offer this kind of wallet-card dispensing capability. Through the machine’s interface, a user can purchase a card, and during the issuance process the system writes the necessary bitcoin wallet data directly onto the NFC-compatible chip embedded in the card. General Bytes says the cards are not programmed in advance; instead, the data is written only after the sale is finalized with the end user.
This approach allows the machine to function not just as an on-ramp to bitcoin, but also as a wallet creation and delivery point. That could be meaningful for new users who may not want to install software wallets or navigate more technical setup procedures before obtaining a usable payment tool.
Built Around WIF and NFC Chip Storage
To make the card-based wallet system work, General Bytes implemented architecture that includes WIF, or Wallet Import Format. This enables bitcoin keys to be stored on the card’s NFC chip. While the company did not position the card as a replacement for all wallet types, it presented the product as a practical form factor for payments, petty cash use, and even simple physical-value storage.
The concept appears aimed at blending the familiarity of legacy payment cards with the self-custodied ethos of bitcoin. Instead of relying entirely on software interfaces, the card itself becomes the physical access point. That may appeal to users who prefer tangible payment tools or merchants looking for easier customer flows at checkout.
General Bytes also noted that the cards can be produced in multiple formats. While the default version is black, the company said they can also be printed in full color. ATM operators can additionally offer branded cards and pre-loaded versions, opening the door to customized deployments for events, venues, retail concepts, or specialized bitcoin service providers.
Tested With CortexPay POS Terminals
On the merchant side, General Bytes said the wallet cards have been tested with the CortexPay POS terminal, a payment device launched in 2015. The company pointed to usage by visitors at Paralelni Polis in Prague as evidence that the broader payment setup has seen real-world activity. Based on those tests and deployments, General Bytes described the system as reliable.
The importance of that compatibility is hard to overstate. Payment products rise or fall on the quality of the end-user experience at the checkout counter. If the transaction feels immediate and natural, merchants are more likely to see value in supporting the system. By pairing ATM-issued NFC wallet cards with an existing POS environment, General Bytes is trying to show that the model can function in practical, customer-facing settings rather than as a purely experimental concept.
Inspired by the Biohacking Community
Interestingly, the idea did not emerge in isolation. General Bytes said the project was inspired by the biohacking community, where some users have already experimented with NFC bitcoin wallet implants. While that niche has demonstrated one possible future for contactless crypto interactions, the company acknowledged that implants are not a mainstream option. A physical NFC card, by contrast, offers a much more accessible middle ground.
That origin story highlights how fringe experimentation can influence more commercial product development in crypto. What begins as a highly specialized or provocative idea can eventually be reworked into a format suitable for everyday users. In this case, the company appears to be translating the same convenience principle—tap-based access to bitcoin—into a more familiar and widely acceptable object.
General Bytes Wants to Move Beyond QR Codes
One of the most notable parts of the announcement is the company’s direct challenge to QR codes. General Bytes marketing manager Martijn Wismeijer said QR codes are gradually being replaced by Bluetooth and NFC tag technology. He argued that removing QR-based interaction not only helps retire what he described as an outdated format, but also reduces the need for mobile phones in many cryptocurrency applications.
From the company’s perspective, this is not just a hardware update. It is a usability argument. QR codes have long been central to bitcoin payments because they offer a simple way to transfer addresses and invoice data visually between devices. But they also introduce steps that can feel cumbersome in retail environments: opening a wallet, focusing a camera, waiting for a scan, and confirming the payment details. NFC promises to compress that sequence into a faster motion.
Wismeijer framed this as a win-win: simpler for the user, more natural for payment settings, and potentially more scalable for broader adoption. He said General Bytes hopes to help make bitcoin a “swipe-to-pay” cryptocurrency that anyone can use. The company’s message is that the hardware needed to support that shift is already available.
Positioning the Card for Everyday and Stored-Value Use
General Bytes said the cards are suitable for day-to-day payments, petty cash, and storage. If the card is not being used with a point-of-sale device, the company suggests it can still function as a kind of physical savings tool. That framing places the product somewhere between a consumer payment card and a portable wallet medium.
For users, the appeal may lie in flexibility. A single card can potentially support spending in compatible environments while also acting as a compact holder for wallet data. For operators and merchants, the product could create new service models around ATM issuance, branded wallet distribution, or venue-specific crypto payment experiences.
Still, the larger significance is strategic: General Bytes is betting that making bitcoin easier to handle in the physical world matters just as much as software innovation. In an industry often focused on apps and protocols, the company is emphasizing hardware ergonomics and payment simplicity.
Open-Source Hardware and Software Strategy
General Bytes also noted that its hardware and software are open source on GitHub. That detail may be important for developers, ATM operators, and technically minded bitcoin users who want transparency into how the system works or who may wish to build on top of the company’s infrastructure.
Open-source availability can help encourage experimentation, third-party integrations, and trust among users who prefer systems that can be independently inspected. In the context of a wallet product—especially one involving stored keys and payment rails—that openness could play a meaningful role in adoption among the more technically engaged segment of the bitcoin community.
Why This Matters
The launch of NFC bitcoin wallet cards reflects a familiar theme in crypto: usability remains one of the biggest barriers to mainstream adoption. General Bytes is not claiming to reinvent bitcoin itself. Instead, it is trying to improve how people interact with it in retail and real-world settings. By moving wallet access onto an NFC card and tying issuance to ATM hardware, the company is presenting a model that could reduce friction for both first-time users and repeat spenders.
Whether NFC cards can truly displace QR codes across crypto payments remains to be seen. QR infrastructure is deeply embedded in wallets, merchant tools, and user habits. But General Bytes is making a clear case that contactless card-based interaction may offer a more intuitive path for some payment scenarios. If bitcoin is to function more like a consumer payment instrument, the company believes the experience needs to become faster, more physical, and less dependent on smartphone screens.
For now, the BATMThree XXL+ is available to those interested in operating a bitcoin ATM, and General Bytes appears ready to test whether its vision of tap-enabled bitcoin payments can gain traction. The company’s bet is straightforward: if paying with bitcoin is made to feel simple enough, more people may actually do it.
