Square introduced strong encryption on its devices, and neither card numbers, nor magnetic stripe data, nor security codes are stored on Square client devices. Dorsey called VeriFone's claims "neither fair nor accurate", noting that all card data can also be compromised by visually examining the card and that even if there were a compromise, card issuers offered fraud protection. VeriFone posted a demonstration video and sample skimming app to its web site. In April 2012, rival payment company Verifone claimed that the Square system at the time was insecure and that a reasonably skilled programmer could write a replacement app which could use the Square device to skim a credit card and return its details, because of the lack of encryption. The original version consisted of a simple read head directly wired to a 3.5 mm audio jack, through which unencrypted, analog card information was fed to smartphones for amplification and digitization. It accepts credit card payments by connecting to a mobile device's audio jack.

On December 1, 2021, Square announced that it would change its company name to Block, Inc. Jay-Z, as well as other artists who currently own stock in Tidal will remain stakeholders. Square will pay $297 million in cash and stock for Tidal, with Jay-Z joining the company's board of directors. On March 2, 2021, Square reached an agreement to acquire majority ownership in Tidal. The company purchased an additional $170 million worth of Bitcoin (approximately 3,318 bitcoins) in February 2021, bringing Square's total holdings to almost $500 million in Bitcoin (total approximately 8,027 bitcoins). In October 2020, Square put approximately 1% of their total assets ($50 million) in Bitcoin (4,709 bitcoins), citing Bitcoin's "potential to be a more ubiquitous currency in the future" as their main reasoning. The name "Square" derives from the company's square-shaped card readers. Ĭo-founders Dorsey-who also co-founded Twitter-and McKelvey began developing the company out of a small office in St. The original inspiration for Square occurred to Jack Dorsey in 2009 when Jim McKelvey (a friend of Dorsey) was unable to complete a $2,000 sale of his glass faucets and fittings because he could not accept credit cards.
