Edit row with simple scan, is possible?

[SantiagoS1]

Hi, first, sorry for my english
how can i change data with barcode scanner?
I explain my case.
(app is in still in project)
My main client is a car rental company and my mission is clean, transfer, fill the tank, check inspection, etc.
to create a line in job table we scan the car key (barcode each car to identify the car). This process is very fast. Single scan with auto reopen form add a row in job table and write de status of car in “in custody”
for now, when i return the car key to my customer i have an action to change status of car to “delivered” selecting the cars which are ready to delivered and click buttom,
My question is ,
is possible change this status using the same way as entry form? mean, single scan with auto reopen?

Selecting from a list can induce mistakes (many cars with similar licence plates). if i can return the cars to my customer with single scan will be great!

Thanks
