Pizza Express, the 384-strong chain, has become the first company to launch an iPhone app that will allow customers to pay their bill at any time during their meal. The Gondola-owned chain said the new app, which is free to download from Apple and goes live today, links up with customers’ PayPal accounts so they can complete their whole payment transaction in under a minute, taking the “stress out of waiting to pay the bill”. Below are the steps for making a payment through the new app, according to Pizza Express, which first appeared in Mobile Industry Review: Step 1. Once you have placed your order in any one of our 384 restaurants, you can ask for your bill whenever you want. Whether that is when you place your order, at some point during your meal or at the end of the meal. It is up to you. Step 2. All you have to do is click on our app, select the ‘Pay Your Bill’ option and enter the 12 digit code, which will be clearly marked on the bottom of your bill. Step 3. Once your bill appears, you can check the amount on the app matches your bill and add a tip if you wish. Step 4. You will also have the option to redeem against a valid offer code or voucher and your total bill amount will be automatically amended. Step 5. Then log in to your PayPal account or enter your credit or debit card details and press ‘Pay Now’. Step 6. Once payment is received the app will send you and our tills a confirmation that will let us both know you have paid. You will also receive an email confirming your payment and you can view your full receipt in the ‘My Receipts’ section of the app. Yesterday, the pizza chain signed an agreement to offer free wi-fi at its restaurants nationwide. The agreement with wi-fi provider, The Cloud, will allow customers to browse the internet, catch up on email, stream video and music and interact with a range of mobile applications from dedicated in-store hotspots.
