In my consulting (to merchants wanting to accept bitcoin) WoS compete with the Blink most often. WoS now improved only in one aspect - self custody. Also has better privacy because does not require phone number. But Blink is better in this: - Much better UI - Stablecoin (not much relevant in North America and Europe) - has great API so: - we can build things around it - many alternative POS on the GitHub covering different needs - @btcpayserver plugin
