how technology is improving productivity in the service sector, e.g. contactless payments

4.2.1 The use of technology in the production of goods and services

Why technology matters in the service sector 💡

Technology is like a super‑speed train for services. It cuts waiting times, reduces errors, and lets staff focus on what really matters – the customer. Think of a coffee shop: instead of writing orders on paper, a tablet can instantly send the order to the kitchen, saving time for the barista to chat with customers. 🚀

Contactless payments 📲💳

Contactless payments let you pay with a tap or a wave of your phone or card. It’s like having a magic wand that instantly transfers money, so you never have to fumble for cash or wait for a cashier to count it. The process is quick, secure, and convenient for both customers and businesses.

1. Customer taps their phone or card on the reader.
2. The reader sends a secure signal to the bank.
3. The bank authorises the payment in < 1 second.
4. Money is transferred instantly and the receipt is sent to the phone.

Other technology examples in services 🌐

• AI chatbots that answer FAQs instantly.
• Online booking systems that let customers reserve slots 24/7.
• Virtual reality tours for real‑estate viewings.
• Wearable health monitors that send data to doctors.

Impact on productivity 📈

Productivity can be measured as the ratio of output to input. In the service sector, technology reduces the input (time, effort) while keeping or increasing output (number of customers served). The formula is:

$P = \frac{\text{Output}}{\text{Input}}$

For example, a restaurant that used to serve 50 customers per hour with manual orders might now serve 80 customers per hour after adopting tablets and contactless payments, while the staff effort stays the same. That’s a 60 % increase in productivity! 🚀

Case study: Fast‑food chain 🍔

A fast‑food chain introduced a mobile app that lets customers order, pay, and pick up without standing in line. The app uses contactless payment and sends the order directly to the kitchen. Results after six months:

The technology didn’t just speed things up – it also made the experience smoother and happier for customers, which in turn boosted sales. 🎉
