[telegram] hazme en inglés, un texto explicando con flechas, el flujo muy simple de cómo se paga en máquina expendedora. Muy grandes rasgos para explicar el rol del código QR


Simple payment flow for a vending machine:

User chooses product
→ Machine shows payment option
→ User scans the QR code
→ QR opens the payment page/app
→ User confirms payment
→ Payment system approves transaction
→ Machine receives confirmation
→ Machine dispenses the product

Role of the QR code:
The QR code is the bridge between the physical machine and the digital payment flow. It connects the user to the correct payment session so the system knows which machine and purchase to charge.

# ballbox-company

## Purpose

Load the Ballbox company operating context when the request is about Ballbox.

## Workflow

1. Use the Ballbox namespace at `/mnt/rpi/repos/ballbox-company-agent` as the working context root.
2. Read `/mnt/rpi/repos/ballbox-company-agent/AGENTS.md` and follow its rules.
3. Use `/mnt/rpi/repos/ballbox-company-agent/index.md` as the default dashboard entry point.
4. Prefer shared-memory search before assuming facts; avoid invented certainty.
5. If the work implies repo/code changes, delegate to `~/ai-dev-workflow`.


**Searching for memories**

I'm thinking about searching my memories and maybe looking for something in my local repository related to QR or webview. There's likely some useful information there that could help! I'll make sure to dive into both areas because I want to find the best resources for these topics. I really hope I can find the connections that might make this task easier and more efficient for anyone who needs it!

TCN buyer QR uses on-screen display, not scanner hardware

TCN Protocol 2.5V states extra hardware is needed to scan QR codes, but the payment flow (FunCode=8000) returns CodeUrl for QR generation. Decision: treat scanner hardware warning as machine-side scan-only; Ballbox production vending payments should integrate through a TCN adapter and let the machine display the buyer QR. Keep /admin/payments QR page as an operator test/debug harness.

**Investigating payment integration**

I think I need to inspect the repo for the ballbox payment integration. It's got me wondering if I should search a bit broader to gather more information. There could be useful insights or related topics that might help. I'll keep my focus on understanding how the integration works and any challenges that might arise, as well as looking for best practices. Overall, I think deeper exploration is the way to go!

**Searching for payment info**

I’m starting to think that the payment repo might not be available here. Maybe I need to check it on my laptop? I think I saw a reference to "hay mencion..." that might relate to a document within the company agent. I’ll search for "MML" in the company agent to find any relevant information related to payments. Let’s see if that helps me figure things out!

# Product Surface

## Goal

Map the Ballbox software and hardware control surface.

## Scope

- payment flow
- dispense integration
- screen playback
- campaign reporting

## Questions

- what is already implemented vs mocked?
- where is the source of truth for transactions?
- what hardware events matter operationally?


(no output)

Command exited with code 1


Sí, pero no veo mención clara a:

- “QR externo dentro de una webview”
- ni una nota explícita de que “la app MML abre un webview para mostrar ese QR”

Lo que sí aparece del flujo es más bien esto:

máquina / launcher Android
→ abre página de pago
→ se muestra QR al comprador
→ pago aprobado por webhook/callback
→ máquina recibe confirmación
→ dispensa
→ success UI

Y además hay una decisión guardada más explícita:

- el QR lo muestra la máquina en pantalla
- no depende de hardware escáner para ese paso
- el `CodeUrl` viene para generar/mostrar el QR comprador

O sea: el material que encontré habla de “mostrar el QR en la máquina” y de “launcher/app → página de pago → callback”, pero no prueba todavía que el detalle técnico sea exactamente “QR externo renderizado en una webview”.

Si quieres, busco el doc/fuente exacta y te saco la cita literal.

**Searching for files locally**

I need to search for files on my local system. It might be helpful to ask where the documents are located, but I can also try searching for PDF or DOC files in my home directory, specifically looking at attachments. I think I could use a bash command to find the likely files quickly. There’s a lot I can check, and getting organized could save me time!

TECHNICAL_LEARNINGS.md:8:- **Selectors (Playwright Context):** The UI uses Ant Design. Sidebars are `.ant-layout-sider`.

- **Connectivity:** 4G module is present. Supports Wi-Fi and Ethernet as failover.

## Integration Logic (Third-Party Payments)
- **The "Justin Chat" Context:** Justin (TCN contact) confirmed that 3rd party payment integration is standard and used by most customers. This suggests the TCN launcher has a native "External Payment" configuration field.
- **Mechanism Theory:** The machine likely calls a configured URL to get a QR code/payment payload and then waits for a server-side "Release Item" command (Remote Vend) or a success callback.
- **Integration Points:**
    - `Payment > Payment`: Currently has a PayPal template.
    - `Remote Track Configuration`: A VIP feature that must be enabled to allow price/stock sync and potentially remote vend triggers.
- **Keywords for Future Research:** `Remote Vend API`, `External Payment Protocol`, `Third-party QR`, `OurVend Callback`.

## Connectivity and Network
- **SIM Cards:** Local SIMs (AR) are necessary due to latency issues with factory roaming SIMs.

Updated #1 (in_progress → completed)


Sí. En esos docs pasados aparece esto:

Lo más cercano al flujo QR:
- `（中英）云数后台操作说明文档(界面英文版).txt`
  dice:
  - “waiting page for payment with mobile phone code scanning”
  - y que se puede cambiar la imagen de esa
    “payment waiting page”

Tramo literal útil:
- “Function: Enable the advertisement
  on the waiting page for payment
  with mobile phone code scanning...”
- “the picture on the waiting page
  for payment with mobile phone
  code scanning will be changed...”

Qué implica:
- sí hay una pantalla/estado de pago
  por QR en la máquina
- parece haber una “payment waiting
  page” dentro del flujo de máquina

Qué NO encontré en esos docs:
- mención explícita a “webview”
- mención explícita a “QR externo”
- mención explícita a que la app MML
  abra una URL externa en navegador
  embebido

Además, en `TECHNICAL_LEARNINGS.md`
hay una nota de trabajo, no doc vendor:
- “third party payment integration is
  standard”
- “machine likely calls a configured
  URL to get a QR code/payment payload”

Pero eso es inferencia/handoff, no prueba
documental del PDF.

Conclusión corta:
- sí hay soporte documental de una
  “payment waiting page” ligada a QR
- no vi prueba documental de
  “external QR shown in webview”

Si quieres, te preparo una respuesta en
inglés con wording seguro:
“the docs mention a QR-based payment
waiting page, but do not explicitly
state that it is rendered via an
external webview.”


[telegram] me preocupa que por mala comunicación haya entendido que se puede integrar un sistema de pagos sin hardware extra. eso quiero validar


**Clarifying payment options**

I need to provide a concise answer about shipping without a payment system and local install. The documentation indicates there's a QR payment waiting page along with some payment parameters. There seems to be some ambiguity that I should mention, particularly concerning what needs validation. My goal is to ensure the user understands the options clearly and what requirements must be met for the process to work smoothly.

Sí. Esa preocupación es válida.

Con solo estos docs, no queda probado
que “se puede integrar pagos sin
hardware extra” en el sentido fuerte.

Lo que sí dicen:
- existe flujo de pago por QR /
  “mobile phone code scanning”
- existe “payment waiting page”
- existen “payment parameters”
- la máquina puede venir “without
  payment system” y el cliente instala
  localmente el sistema de pago

Eso último mete ambigüedad fuerte:
- puede significar que para pagos
  cashless normales esperan hardware
  local
- y que el QR flow sea solo una
  modalidad soportada bajo cierta
  config/protocolo, no garantía de que
  cualquier PSP externo funcione sin
  hardware adicional

Entonces, con estos docs:
- NO validaría todavía la frase
  “no hace falta hardware extra”
- Sí validaría:
  “hay indicios de flujo QR en pantalla,
  pero falta confirmar si eso reemplaza
  hardware de pago o si convive con él”

Lo crítico a confirmar con TCN/MML:
1. ¿El QR se genera desde una URL
   externa/tercero o solo PSPs ya
   integrados por Yunshu?
2. ¿La máquina puede vender solo con
   QR en pantalla y callback remoto,
   sin lector/pinpad/validador extra?
3. ¿Qué protocolo exacto usa para:
   crear orden → mostrar QR →
   confirmar pago → disparar vend?
4. ¿Qué significa exactamente en su
   contrato “without payment system”?

Te recomiendo wording seguro:
“The documents suggest a QR-based
payment flow exists, but they do not
clearly confirm that third-party
payments can be integrated without
additional payment hardware.”

Si quieres, te redacto 3 preguntas muy
afiladas para mandarles hoy.


[telegram] mml no es un termino real. se me escapo escribiendo

que es psp?


PSP = Payment Service Provider.

Es la empresa/plataforma que procesa
el pago.

Ejemplos:
- Mercado Pago
- Stripe
- Adyen
- PayPal

En este contexto:
- si dices “PSP externo”
  quieres decir un proveedor de pagos
  ajeno al sistema nativo de la máquina
  o de Yunshu/OurVend.


[telegram] esto hable con soporte de tcn recien

[15/5/26, 16:35:49] Sebas: i wanted to ask about specifics on what the system expects as return schema for external payments using QR, so it knows to dispense product on successful payment
 [15/5/26, 18:48:40] ~ Service Mia: Our machine is linked to your payment account. Once the customer successfully pays, the vending machine will dispense the product. If it fails to dispense the product, the vending machine will send a refund command to the payment device. All subsequent operations will need to be handled by you on the payment platform.
 [15/5/26, 19:43:53] Sebas: thanks, and by payment device you mean something extra connected to the VMC?
i was planning on showing a qr code on the android app itself and resolve the payment there. Is that not possible?
 [15/5/26, 19:49:43] ~ Service Mia: Of course you can. You can view successful payment records in your payment account and issue refunds to customers through your payment account.
 [15/5/26, 19:53:35] ~ Service Mia: Refunds cannot be processed on the machine screen.
 [15/5/26, 19:54:39] Sebas: what i planned for was this for the usual payment flow:

User chooses product
→ Machine shows payment option
→ User scans the QR code
→ QR opens the payment page/app
→ User confirms payment
→ Payment system approves transaction
→ Machine receives confirmation
→ Machine dispenses the product
 [15/5/26, 20:03:13] ~ Service Mia: This is exactly the dispensing process of our vending machines.
 [15/5/26, 20:14:40] Sebas: oh okay! sorry got confused

then do you have a manual on setting it up or is it easy?
it’s one link to a qr code per product?
 [15/5/26, 20:30:40] ~ Aftersales Management Eve: Good day sir, how are you? Please call me Eve. I am a little bit confused. Do you want to display a QR payment code on the machine so that customers can scan the code to pay and then the machine will complete the shipment?
 [15/5/26, 20:31:14] ~ Aftersales Management Eve: Because you just mentioned that you believe this is a normal purchasing and shipping process.
 [15/5/26, 20:59:41] Sebas: Hi Eve!
 [15/5/26, 21:00:12] Sebas: Yes exactly
 [15/5/26, 21:01:12] Sebas: I believe I saw on some manual the app displayed a WebView for showing the QR

I need to interpret the conversation carefully to avoid any ambiguity. It's important to suggest next precise questions that could clarify things. I might also want to mention that the "webview" isn't established yet. Keeping everything concise is key, as I don't want to overwhelm the user with too much information at once. Making the dialogue smoother and more understandable is my goal here. Let's see how that works out!

Bien. Esto cambia bastante.

Lo que sí podés tomar de ese chat:
- soporte confirmó el flujo deseado:
  QR en máquina
  → cliente paga
  → máquina dispensa
- también confirmó que refunds van
  fuera de la pantalla/máquina

Pero sigue habiendo ambigüedad crítica:
- Mia dijo que la máquina está ligada
  a “your payment account”
- también habló de “payment device”
- Eve después mostró confusión
- nadie confirmó todavía el contrato
  técnico exacto

Punto importante:
- vos les dijiste “I believe I saw...
  a WebView”
- eso salió de vos, no de ellos
- por ahora no lo tomaría como
  confirmado por TCN

Mi lectura:
- ya hay señal fuerte de que
  QR-on-screen sí es posible
- todavía no hay validación técnica
  de cómo se integra:
  - URL externa
  - schema de respuesta
  - callback
  - polling
  - order id
  - trigger de dispense

Lo mejor ahora es cerrar ambigüedad con
preguntas muy concretas. Mandales esto:

1.
When you say this is possible,
does the machine support showing
a QR code generated by our own
external payment system on the
Android screen, without any extra
payment hardware connected to the VMC?

2.
If yes, what is the technical
integration method?
Is it:
- a URL/web page shown on screen
- an API returning QR content
- or a payment device protocol?

3.
What exact signal tells the machine
to dispense after successful payment?
Please share the request/response
format or protocol documentation.

4.
Do you have a setup manual for this
external QR payment flow?

5.
Is the QR linked per product,
or is it generated dynamically per
order/selection?

Frase clave para no autoengañarse:
- “commercial confirmation: likely yes”
- “technical confirmation: still no”

**Interpreting screenshot content**

I'm looking to provide an answer about a screenshot. I think I could read the attachment directly without needing OCR since the text is already in the image. My goal is to be concise and get straight to the point to help the user understand it better. Let's see what the content reveals and how best I can summarize that information!

Esto aclara bastante más.

Nueva señal fuerte:
- no están hablando de hardware extra
  en esa respuesta
- están hablando de integrar Mercado
  Pago API con su “standard payment
  software”
- incluso dicen que su software team
  puede tener que hablar con la
  payment company

Mi lectura ahora:
- sí parece viable integrar un flujo de
  pago QR sin hardware adicional
- pero no como “poné cualquier webview
  y listo”
- más bien como integración formal con
  su software de pagos estándar

O sea, el modelo parece ser:
tu backend / Mercado Pago
→ integración con software TCN
→ máquina sabe que pagó
→ dispensa

No prueba todavía:
- si el QR lo muestra una webview libre
- si hay API pública/documentada
- si requieren desarrollo interno suyo
- si el flujo queda por producto o por
  orden dinámica

Pero ya podés decir algo bastante más
fuerte:

“TCN support indicated they can connect
our Mercado Pago integration into their
standard payment software, potentially
with involvement from their software
team. This suggests the QR payment flow
may work without extra payment hardware,
but it still needs technical validation
on the exact integration method.”

Siguiente mensaje ideal para ellos:

Thanks, that helps.

So just to confirm:

1. This can work without extra payment
hardware connected to the VMC, correct?

2. Is the integration done through your
standard payment software team, rather
than by simply opening our own web page
inside the Android app?

3. Do you have technical documentation
for:
- order creation
- QR generation/display
- payment success callback
- dispense trigger

4. Can your machine request a dynamic
QR per purchase, or do you expect a
fixed QR/payment config per product?

Si quieres, te lo dejo más corto todavía
para WhatsApp.


[telegram] me buscas la api que piden de MP? quiero pasarselas y que me den un tiempo de entrega aproximado (porque si dicen que tardan semanas voy con el hardware)
