Ringup helps voice agents recognize callers by phone number alone, so they can greet them, remember their usuals, and charge their saved card in seconds. Payments settle directly on the merchant's existing processor.
Drops into your existing agent, live in an afternoon
01 — The problem
Your agent still doesn't know who's calling. #
Voice AI books the table, takes the order, files the claim. But every call starts from zero: the regular gets treated like a first-timer, reading out a 16-digit card number every time a payment comes up.
The agent takes the order instantly, but the caller is a stranger: no name, no saved card. They still drive over and stand at the register to pay, adding lines for diners and work for staff.
The agent greets the regular by name, confirms the usual, and charges their saved card on the call. The order is prepaid, labeled, and ready at pickup.
Deposits and no-show fees mean asking every guest to read a card to a bot, so most agents skip them and no-shows eat the night.
Recognized guests confirm the deposit in one sentence: “your Visa ending 5858?” First-timers tap a texted link. No digits spoken, every booking backed.
Identity by interrogation: name, date of birth, account number, then a card keyed digit-by-digit into the keypad, on every single call.
The phone number is the identity: carrier-verified, matched to the account, and the balance settled from a saved card in one sentence.
The hardest call in the book gets harder at the finish: the payer must dig out a card and read 16 digits before a promise-to-pay becomes money.
The moment they agree, it's done. The saved card is charged on the call, or a one-tap link lands by text while they're still on the line.
Every ticket opens with an interrogation (“name, email, order number?”) before the actual problem is even on the table.
identify returns who's calling before the first hello. Your agent opens with their history in hand, and if something's owed, it's one sentence to settle.
The counter quotes the part and holds it unpaid. Half the holds never show, and chasing cards by callback burns the counter's day.
Regulars are recognized on the first ring. The part is held and paid in the same breath, charged to the card on file.
02 — How it works
Phone as the payment identity #
The first time someone pays, they're saved, keyed to the number they call from. Every call after, they're recognized instantly. Either way, paying takes seconds and never leaves the conversation.
Pay in one tap. Saved for next time.
A link arrives by text
While they're still on the call, a secure pay link lands in their messages. No app to download, no portal to log into.
They pay, their way
One tap with a digital wallet, or add a card or bank account, saved with their consent, nothing read aloud, nothing typed.
Done before they hang up
The payment confirms on the call, and they're recognized instantly the next time they ring.
Recognized by number. Paid by voice.
We already know them
The moment they call, Ringup returns their name, saved card, and any context you've attached. Your agent greets them by name, not a form.
They just say yes
"Charge your card on file for $24?" "Yep." That spoken yes is the entire checkout.
Paid in seconds
The charge clears mid-conversation and the confirmation is read right back to them.

06 — FAQ
Questions, answered. #
What is Ringup? #
How is Ringup different from Stripe Link and other wallets? #
Why Ringupsection above.
How does a customer pay during a call? #
Is your solution 2FA-compliant for payments? #
possession of the line (the call comes from the number itself) and its
carrier-verified integrity(checks that the SIM hasn't been swapped and the line hasn't just been ported or forwarded). The biggest weakness of SMS two-factor is the SIM-swap: moving a number to a new SIM so the codes follow. Ringup detects exactly that, and there's no one-time code to phish. You get every assurance of 2FA, plus a defense against the attack that usually beats it.
