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
