Shoppers are encouraged to use contactless payment methods when they are making essential trips to the supermarket.
Contactless is preferred to cash during the coronavirus pandemic as it reduces contact between people and allows for social distancing between shoppers and till staff.
But contactless, either through a card or phone, is not available to everybody all of the time and there are those who prefer to use cash when paying for goods.
While the UK's major supermarkets all say they would prefer customers to use contactless when they can, it does not mean they will not accept cash at all.
Can I pay with cash in Aldi, Asda, Iceland, Lidl, Morrisons, Sainsbury's, Tesco and Waitrose during the Covid-19 lockdown?
Here are Aldi, Asda, Iceland, Lidl, Morrisons, Sainsbury's, Tesco and Waitrose's policies and advice on paying with cash during the coronavirus lockdown. You can read up on the latest supermarket rules, here.
Aldi
Shoppers are encouraged to use cards in all stores, but customers who need to pay in cash can still do so.
Aldi said: "Yes we are still accepting cash payments in our stores, however, we are asking customers to use contactless forms of payment where possible."
Asda
Contactless payment is encouraged at Asda, as is use of its scan and go machines, which the supermarket says speed up shopping and reduce contact between customers and staff.
Customers can still pay in cash if they need to.
Asda said: "To help reduce contact in our stores we've also rolled out 'Scan and Go' mobile to all of our supermarkets, superstores and supercentres.
"Customers can use their own device to scan their shopping and pack as they go.
"Many of our larger stores also offer Scan & Go handsets in addition to Scan & Go mobile.
"To use your own device in store please visit the app store and download the free Asda Scan & Go app.
"Contactless payments - Credit and debit card contactless payment limit amount has now been increased to £45."
Iceland
Customers can pay with cash at Iceland and Food Warehouse, but contactless payment is preferred.
Iceland said: "We continue to accept cash payments in all our Iceland and The Food Warehouse stores, though we recommend that customers make payment by contactless card wherever possible to reduce the risk of Covid transmission."
Lidl
Customers can use cash if they need to, but contactless methods are preferred.
A Lidl spokesperson said: "Yes, we are still accepting cash payments in our stores although we continue to encourage customers to use contactless payment wherever possible."
Morrisons
Customers shopping in-store can use cash in Morrisons, but, as with other supermarkets, contactless payment methods are encouraged.
Sainsbury's
Customers who prefer to use cash are asked to make use of Sainsbury's self-checkouts, which accept cash and avoid contact between cashiers and customers.
A spokesperson said: "We would like customers to pay by card. If you would like to pay by cash, please use our self-service tills.
"SmartShop is available in Sainsbury’s supermarkets and helps you spend less time in-store and reduces contact by letting you scan your own shopping and check out through a dedicated till area."
Tesco
It is fine for customers to pay with cash, but contactless methods will help customers maintain social distancing guidelines, so they are preferred if possible.
As with Sainsbury's, cash customers can consider using the self-check out tills to reduce contact with staff.
Tesco said: "Since the start of the pandemic, we’ve focused on ensuring everyone can get the food they need in a safe environment.
"Our safety measures are there to protect you and our colleagues, as we all follow the latest government guidance."
Waitrose
Contactless payment methods are encouraged, but cash is accepted, a Waitrose spokesperson confirmed.
