BAV — try the hard split

Not another tracker. Two pots: rent-safe money and spending money. The demo declines anything that would empty the spending pot early. No real money, no bank details.

Early demo. Give feedback · Join the tester list

How to feel the point in 2 minutes
  1. Set your next loan date (or keep the example) on the Wallet Card.
  2. Switch to Till, scan a big discretionary item (headphones, trainers, night out), request payment.
  3. On the Wallet Card, try to pay — watch the warning or the automatic decline.

One device is enough: toggle Wallet Card ↔ Till at the top. Two devices (laptop + phone) give the live handoff.

Each visit gets its own session with its own random code, so other people testing at the same time never see your changes. What you enter is stored under that code only so your screens can sync. Please use made-up details.

Three declined attempts in a row were detected. This is a security pause, not a lock-out — you're always in control of your own card.

Make it about your term
How is my security protected?
This demo never touches a real bank account. If BAV became real: no bank logins or passwords would ever be stored by BAV. Access would go through UK Open Banking — a regulated standard that many UK banks and apps already use, designed for read-only, revocable access — never screen-scraping or password storage. You could revoke access at any time from your own bank's app.

Retail counter
Scan items, then request payment. To feel the point: add a large spending-money item (headphones, trainers) and watch what happens when it exceeds the pot.
This card is currently frozen after repeated declines. The student needs to unlock it on their phone before another payment can be requested.
