Add a self-checkout feature in campusM/Library Mobile

It would be useful to add a self-checkout function to campusM/Library Mobile. Built as a new product integration, notably with Alma, it would allow patrons to check out items on their mobile device (quick and private way for patrons to borrow items from anywhere in the stacks). Some libraries use parallel apps for self-checking, it is not very convenient to propose different library apps to users. Adding a self-checkout feature in campusM/Library Mobile would consolidate the use of this app among the library patrons.
