You now have the option to collect the recipient's signature during checkout. This works especially well when checking out assets on a phone or tablet - recipients can draw their signature right on the screen!
Signature collection is only available when checking out to a person - it will be disabled if you're checking out to a location alone.
Assetbots will remember your selection, so if you choose to collect a signature for a checkout, signature capture will be automatically selected for your next checkout.
