Buzzer
Scan once at checkout. Get a push notification on your phone when it's time to pick up — no physical pagers, no SMS.
Pay at a participating merchant like you normally would.
Open Buzzer and scan the order code at the counter or on your receipt.
A push notification tells you when to pick up — no physical buzzer, no waiting around the counter.
Already use your email for receipts or rewards at checkout? Buzzer may recognize you as a returning customer, so you might not need to scan a QR code after each order.
Run a cafe or restaurant? See Buzzer for merchants.
