## The panel's verdict

YAVIN is a French card-payment product: an iPhone (XS or newer, iOS 17, passcode set) becomes the terminal, taking tap-to-pay sales with tips, PIN-protected reversals and receipts by email or QR code. The bench scored it highest on payments and fees and on accounting and portability, both a uniform 4: a named, regulated money chain (YAVIN SAS, registered payment-services agent of the Paris e-money institution eZyness under ACPR supervision) and a genuinely documented version 5 API with sandbox, pagination, an approval-flow refund path and webhooks with retries and idempotency keys. The lowest marks are fiscal compliance, scored 0 with no public information on a TSE, DSFinV-K, RKSV or NF525, and operations and locations at 2 to 3, with no public information on articles, stock, staff rights or kitchen printing. Sovereignty splits the judges, 2 to 4: some weighed the French contracting chain, others the missing data residency, subprocessor list and processing agreement. No prices — licence, terminal or per-transaction — appear on the pages read.

**Speaks for it:**
- Tap to pay turns an iPhone XS or newer (iOS 17, passcode set) into the terminal with no extra hardware, with tips and PIN-protected reversals.
- Payments run through a named, regulated chain — YAVIN SAS as payment-services agent of eZyness, an e-money institution authorised by the ACPR.
- A documented version 5 server-to-server API offers a sandbox, paginated transaction retrieval with filters, refunds with an approval flow, and webhooks with a retry schedule and idempotency keys.
- A WooCommerce plugin, an iOS SDK and an online-payment drop-in integration are named alongside the API.
- Accepted schemes include CB, Visa, Mastercard, Amex and Maestro, plus French meal-voucher mediums such as ANCV, Edenred and Swile.

**Held against it:**
- Fiscal compliance scored 0, with no public information on a TSE, a DSFinV-K export, RKSV or NF525 on any page read.
- Operations and locations scores range 2 to 3, with no public information on articles, stock, staff roles, tables or kitchen printing.
- We found no public information on where sales and customer data are hosted, on a subprocessor list or on a data processing agreement; the only host named is Webflow Inc of San Francisco, for the website.
- We found no public information on a named accounting export with revenue accounts and tax rates, or on a full export when the contract ends.
- The webhook documentation itself states that requests carry no signature today.

**Best for:**
- You take card payments at a counter or a stall and want one iPhone — XS or newer — as the whole terminal, with tips and receipts by email or QR code.
- You have a developer to integrate: the versioned API with sandbox, webhooks and a WooCommerce plugin lets you pull, refund and reconcile transactions yourself.
- You want a French-regulated money chain, with a Paris-registered vendor acting as payment-services agent of the ACPR-authorised eZyness.

**Avoid if:**
- You face a cash-register audit that requires a certified TSE, a DSFinV-K export or NF525 — fiscal compliance scored 0 and we found no public information on any of them.
- You need a till beyond payment — articles, stock, staff roles, tables or kitchen printing — where operations and locations scored 2 to 3.
- Your data protection officer must see a data residency statement, a subprocessor list or a processing agreement before signing; sovereignty scores ranged 2 to 4 over exactly this.

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion.

### The judges

- **The Café Owner** (v1.0): Runs a café with twelve tables, a counter and a terrace in summer, and closes the till herself at eleven at night. Wants an iPad till the student staff learn in one shift, orders that reach the kitchen printer, split bills and tips without arithmetic, a till that keeps selling when the Wi-Fi drops, a TSE she does not have to think about, and a monthly cost she can still read in the second year.
- **The Retail Shop Owner** (v1.0): Owns a stationery and gift shop with a second branch across town and about four thousand articles, many in several colours. Wants barcodes scanned at the till, stock that shows what the other branch still has, transfers between the two shops, suppliers and reorders in the same back office, vouchers that work in both branches, and the month's sales handed to the tax adviser without a USB stick.
- **The Tax Adviser** (v1.0): Looks after the books of sixty restaurants, bakeries and shops and has sat in on more than one unannounced Kassennachschau. Wants the TSE named with its certificate, a DSFinV-K export that opens in the auditor's software, the § 146a registration done, a procedure documentation that exists before it is asked for, a DATEV export with the right revenue accounts, and ten years of records still readable after the client changes tills.
- **The Hospitality Operations Manager** (v1.0): Runs operations for a group of eight restaurants in three cities with two hundred staff. Wants one menu and price list pushed to every site with local exceptions, staff rights that stop a waiter voiding his own bills, reports that compare sites by the hour, and a works council and data protection officer who can sign off what the till records about employees and loyalty guests, and where it is hosted.
- **The Fee-Conscious Merchant** (v1.0): Sells ice cream from a shop in spring and summer and from a market stall at Christmas, mostly in amounts under five euros, and more of them by card every year. Wants the fee per girocard and credit card payment on the price page, a terminal he can choose rather than the one the till insists on, hardware that runs off a battery, no monthly fee in the closed months, and the real cost of "free".
- **The Skeptic** (v1.0): Has seen a "free" till paid for twice over in card fees, printers that work with one vendor's software only, a TSE charged by the year on top of the licence, and a cancelled contract that left ten years of fiscal journals behind a login. Reads "100 % finanzamtkonform" with no TSE provider named and "DATEV-ready" with no export format — and asks what leaving would cost.
