The Problem: Why Most Telegram Payment Bots Fail You've built a Telegram bot that sells digital courses, takes coffee orders, or offers freelance services. Traffic is flowing. But when your bot tries to collect payment, you hit a wall: Payment gateways demand hefty setup fees and compliance audits You end up holding customer money in an intermediary account (legal liability) Settlement takes 3–5 days, frustrating both you and buyers Integration is a maze of webhooks, IPNs, and error handling A founder we know spent two weeks wrestling with Stripe's Telegram integration, only to discover the monthly fee ate 40% of his margins on $2–5 transactions. He needed something lighter, faster, and truly peer-to-peer. Enter AgentPay VN : an open-source Python SDK that lets your Telegram bot generate QR codes pointing directly to your bank account. No middleman. No holding funds. Just instant VietQR payments via the banking system Vietnameses already use daily. What Is AgentPay VN? AgentPay VN is an MIT-licensed Python SDK + MCP server that orchestrates VietQR payment requests. Here's the mental model: You create a payment request in your bot (e.g., "Customer ordered coffee for 50,000 VND") AgentPay generates a checkout URL with an embedded QR code Customer scans → pays → bank confirms settlement in seconds Your bot receives a webhook callback and fulfills the order The key: AgentPay never touches money . The QR points straight at your merchant bank account. A bank feed confirms settlement. You own the transaction end-to-end. Why Telegram + VietQR? Telegram has 180+ million users , with especially strong adoption in Southeast Asia. Vietnamese merchants already use banking apps (MB Bank, Techcombank, VCB) that natively support VietQR scanning. Your bot becomes a natural extension of their daily workflow: Customer receives a payment link in chat Opens the QR code (in-app or screenshot) Scans with their banking app (2–3 taps) Money clears to your account in minutes Bot auto-confirm

Every time I handed my Aadhaar card to someone for KYC, one thought kept nagging me: Where is this data actually going? Most "digital Aadhaar verification" tools out there silently upload your card details to their servers. You have zero visibility into what gets logged, stored, or sold. For something as sensitive as a national biometric ID, that's a pretty terrible default. So I built AadhaarQRCodeReader — a web app that scans the Secure QR on any Aadhaar card, decodes all the identity details, and does the entire thing inside your browser . No backend. No API calls. No data leaves your device. Ever.

UIDAI added a Secure QR Code to modern Aadhaar cards (and letters) — it's that big QR, not the small one. It's essentially a compressed, binary-encoded snapshot of your Aadhaar record containing: Name, DOB, gender Full address (house no., street, locality, district, state, PIN) Last 4 digits of your linked mobile Email (if yo
