# processReaderPayment

mutation · in the family [Selling](/reference/selling/)

## What it does

Take a card-present payment on the card reader paired to this till.

START one card-present payment on the caller's PAIRED READER: REQUIRES the composite POS session (the x-at-device-session facet — the reader resolves from THE DEVICE, never caller-named: ACTIVE + register-paired, exactly ONE active registered card reader; the device's org chain must equal the order's selling org). The selling org must hold a CONNECTED chargeable account (NO platform arm — the direct-charge money-destination law; CONFLICT/REF_STATE otherwise). Record-first: the Payment mints created with methodRef = the reader's readerRef, THEN the processor intent hands to the reader and this op RETURNS — the customer taps; the payment_intent.amount_capturable_updated truth commits the Tender row + the Order rollup + the created→authorized flip in ONE transaction (the webhook SoT; a fully-delivered order then CAPTURES — the seam), and a reader DECLINE lands the attempt failed via payment_intent.payment_failed. Poll the payment record for the outcome (the CQRS shape). A reader refusal (busy/offline — NO card presented) refuses PAYMENT/READER_UNAVAILABLE with the attempt recorded failed (retryable — record-per-attempt). Requires the unrestricted capability. Template class (the applyTender ring plane — hand-derived v32).

## What happens

The order’s remaining amount goes to the physical reader; the customer taps or inserts; the payment confirms back onto the order.

## Careful

Real card money. A busy or offline reader refuses retryably — the customer has not paid until the reader confirms.

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `input` | [ProcessReaderPaymentInput](/types/ProcessReaderPaymentInput/) `ProcessReaderPaymentInput!` | yes | No further notes. |

## Returns

[Payment](/types/Payment/) `Payment!` — A Payment — a PROCESSOR-backed payment (the integrated processing mode), spawned by a card Tender. Aligned to the deposit→recognition model: authorize = the hold = DEPOSIT at tender; capture = RECOGNIZED at delivery — POS carry-out collapses authorize+capture by ARRIVING at delivery in the same request (the settle instant delivers), never by skipping states. Record-first/processor-after: minted created BEFORE any processor call; the StripePort attempt fires post-commit; state flips ride the ACK/webhook path; 32 attempts bound each order (the Order.paymentIds cap). PCI-min: the PAN never touches AT/stack — the record holds the opaque tokenized methodRef + processor refs + at most brand/last4. The StripePort is FAKED at 7.7a (deterministic, keyless); the live adapter + webhook ingress are 7.7b.
