Our library uses automated lockers to lend laptops to patrons for in-house use. We'd like to block patrons whose cards have expired from borrowing until they come to the desk and renew, while still allowing borrowing for patrons blocked for overdues since these items won't be leaving the library. Our vendor is able to accommodate this for other customers because their ILS sends the patron expiration date in the BW field in the 24 response. Sierra's response only indicates the block in the first position of the patron status element, which includes blocks for all reasons, not just account expiration. We would like Sierra to also send the expiration date in the 24 and 64 responses so we can distinguish expired accounts from other blocks.
