Ringup vs. Shuttle Global: 2026 Comparison
Ringup gives every voice-agent platform the smoother payment flow: caller recognition, voice-approved repeat charges, and 144+ payment providers. Shuttle Global is built around secure in-call keypad capture.
Ringup is the better choice for AI voice agents: it works across every voice-agent platform, recognizes returning callers, and turns spoken approval into a saved-card charge. It also connects to 144+ payment providers while merchants keep their own processor. Choose Shuttle Global when in-call keypad capture is the priority.
The real comparison
| Factor | Ringup | Shuttle Global | Bottom line |
|---|---|---|---|
| Primary approach | Phone-number-based payment identity for AI voice agents | PCI-isolated voice capture and multi-PSP infrastructure | Ringup begins with caller identity; Shuttle begins with secure capture and routing. |
| First-time caller | Secure one-tap link for wallet, card, or bank payment | DTMF card entry during the call or a payment link | Choose whether the first payment should happen visually or by keypad. |
| Returning caller | Recognizes the caller before a saved-card charge | Charges a stored payment-method ID or gateway token | Ringup productizes caller recognition; Shuttle exposes reusable payment references. |
| Card data during call | No card number read to the agent; first-time entry happens on a secure link | DTMF digits isolated from the AI and application audio | Both keep card data away from the AI through different customer experiences. |
| Repeat payment | Recognized caller approves a card-on-file charge by voice | Platform selects a saved method and submits a later API charge | Ringup minimizes caller steps; Shuttle standardizes saved-card operations. |
| Platform scope | Every voice-agent platform via native Vapi handoff or call transfer; nine platform guides published | AI agents, IVR, human agents, chat, and embedded payments | Ringup covers the voice-agent ecosystem; Shuttle spans more traditional contact-center channels. |
| Payment-provider reach | 144+ payment providers; merchants keep their own processor account | Publishes 25+ to 40+ gateways or PSPs by product surface | Ringup publishes the broader provider count while preserving merchant-of-record continuity. |
| Public pricing | Private beta; transaction pricing not publicly listed | $0.20 per Voice Checkout or Links Checkout transaction; embedded pricing custom | Shuttle publishes entry pricing; Ringup requires access or pricing confirmation. |
The real difference is payment identity.
Both products can keep raw card data away from the voice agent. The key distinction is what the system knows before a repeat charge, and what the caller must do next.
A first-time caller receives a secure link, pays, and can consent to save the method against the number they called from. On a later call, Ringup can use the number, carrier signals, and a stored voiceprint to recognize the caller before the agent asks for spoken approval.
Shuttle can pause the AI-agent segment and prompt the caller for card details by keypad. Its documentation shows saved cards returning a payment-method ID and gateway token; later charges use those stored references. Phone number is accepted as customer information, but the reviewed docs do not claim automatic recognition from the incoming call.
Choose the fit for your use case.
You want the better AI voice-agent experience across any platform: caller recognition, a one-tap first payment, voice-approved repeat charges, 144+ payment providers, and settlement to the merchant’s processor.
Secure keypad entry during the call is required, or the same infrastructure must cover traditional IVR, human-agent, and AI-agent workflows. Shuttle also provides a clearer public entry price.
Questions, answered.
Is Ringup better than Shuttle Global?
Ringup is the better fit for AI voice agents because it works across every voice-agent platform and combines repeat-caller recognition, voice-approved saved-card charges, and 144+ payment providers. Shuttle Global is the better fit when in-call DTMF capture or broader contact-center coverage is the priority.
What is the difference between Ringup and Shuttle Global?
Ringup turns the caller’s phone number into the payment identity and optimizes the first-payment-to-repeat-payment journey. Shuttle Global provides PCI-isolated card capture, payment links, reusable payment-method tokens, and multi-PSP routing across voice and other channels.
Is Ringup cheaper than Shuttle Global?
A direct price comparison is not currently possible from public information. Shuttle lists Voice Checkout and Links Checkout at $0.20 per transaction, while Ringup’s public site describes a private beta without publishing transaction pricing.
Can Ringup replace Shuttle Global?
Ringup can replace the customer-facing payment flow for AI voice-agent use cases centered on caller recognition, one-tap first payments, and voice-approved repeat charges. It is not a like-for-like replacement for every Shuttle use case, especially traditional contact-center or keypad-capture deployments.
Who should use Shuttle Global instead of Ringup?
Teams should choose Shuttle Global when callers must enter card details by DTMF during the call or when one payment layer must support traditional IVR, human agents, AI agents, and embedded payment operations.
Do both products keep card data away from the AI agent?
Yes, based on their public materials. Ringup says card details remain in wallets and a PCI Level 1 vault. Shuttle says DTMF card data is isolated inside Twilio, Shuttle, and the payment gateway rather than entering the AI platform or application.
Does Shuttle Global support saved cards?
Yes. Shuttle documents tokenization and charge-plus-save flows, returns a Shuttle payment-method ID and gateway token, and supports later charges through its API using the saved payment-method reference.
Does Shuttle Global identify returning callers by phone number?
Shuttle accepts phone number as customer information, but the public documentation reviewed for this comparison does not describe automatic caller recognition from the incoming phone call. Its saved-card examples use an explicit payment-method ID or gateway token.
