London and other cities are largely card-friendly, but carrying some cash still helps for small purchases and repaying friends quickly.
Practical tips
Contactless is widely available
Many UK merchants accept contactless cards and mobile wallets. For group dinners, designate who pays and log the bill before everyone scatters.
Keep cash for occasional cash-only spots
Some smaller venues may prefer cash or have minimums for cards. Shared taxi fares are easier to split when the payer logs the meter total right away.
Watch for service charges on bills
Restaurants may add a service charge line. Include the full receipt total when splitting so nobody underpays the shared tip or fee.
Use a trip group for city breaks
Weekend trips with shared Airbnb and pub tabs fit well in a KupaPay group — especially when friends join from different cities.
Track shared trip costs in KupaPay
Create a group, log who paid what, and let KupaPay simplify settle-up — on iPhone, Android, and the web.
