@Toshihiro - that is a great idea to eliminate as much as possible any chances of cross-contamination - a "take out" style.

Self serve checkouts are great, but they do not necessarily avoid contamination since food or items displayed may have been previously touched by anyone else. The best way is to wipe the items (wrapped in plastic), canned goods, (1) with antiseptic wipes to deactivate the contagion, (2) leave the items in the shopping bag for 48 hours (in a secure area with no traffic) before using (a study showed coronavirus particles become deactivated after 48 hrs in plastic surfaces, 24 hours in cardboards/paper, and up to 72 hours on metal surfaces).

Puttting the coins onto the tray does not eliminate cross-contamination since they also touch those trays from time to time, unless they regularly disinfect the trays, notwithstanding that other people may have also touched the tray before you.

Regarding wearing gloves: be aware of cross-contamination - unless they are changed each time per customer (which is highly impractical) or disinfect with alcohol after each transaction (while being worn). I have seen a lot of people wearing gloves, touching everything and then hold their phones (texting) which eventually touch their face during calls, or even, shockingly, eat french fries while wearing a pair.

@RainyDay. Hi Rainyday. It is currently difficult to develop a "field kit" for detecting COVID-19. The virus has an RNA genome which require a very sensitive isolation technique. RNA is very sensitive and unstable molecule. This RNA is subjected to a procedure called real-time quantitative PCR which also needs expensive reagents and equipment. Also, these detection procedures should be done in a Class III biosafety facility.

When we had our trip to DiverCity Tokyo Plaza and dined in the mall's food court, the place was packed with Chinese tourists. My brother and I were saddened by the fact that despite instructions written were literally distributed everywhere pleading "Please return all your dishes from the stores where you bought them" with translations in Chinese, the Chinese tourists just ignored them and left all their used dishes on the dining tables including rubbish on the floors. You can clearly distinguish whether the dining tables were used by either Japanese or Chinese. :(
