Jack Dorsey's financial services company Block plans to enable merchants to accept bitcoin at the cash register through Square Point of Sale, using the Lightning Network for quick payments and low fees.
The rollout will happen in two phases, with the first phase starting later this year and potentially all eligible sellers being able to accept bitcoin by 2026, alongside credit cards and cash.
Block's expansion into bitcoin payments adds to its existing range of crypto services, including buying, selling, and sending bitcoin through its Cash App, offering self-custody wallet Bitkey, and supporting bitcoin projects through Spiral.
While merchants will face price volatility if they choose to hold bitcoin, automatic conversions are available to mitigate risks. Regulators will monitor the implementation closely, but if successful, shoppers could see a 'bitcoin' button on Square screens in early 2026.
