EDIT: thanks everyone for quickly correcting my mistake, I missed the part that explained that more forms of contactless payments would be accepted I don't really understand why a merchant would use this feature. If you already use a PoS, why would you replace it with another one that only supports customers who own an Apple device? If you accepted only cash, maybe it's a small improvement because you can use your ex…
What makes you think it only supports payment from Apple devices? The press release is pretty clear:
At checkout, the merchant will simply prompt the customer to hold their iPhone or Apple Watch to pay with Apple Pay, their contactless credit or debit card, or other digital wallet near the merchant’s iPhone
