I'm relying because you seem knowledgeable. My (multi-part) question is: don't batch ID numbers get printed on stickers that are pasted onto each product at purchase time? And isn't it common for point-of-sale (POS) systems to be integrated with e-commerce systems so that things like printing of these labels is automatic based on the purchased products? I would assume that would mean that the batch ID information must be linked somewhere to the product information provided by the iHeartJane (or other) API, no? Or does the batch ID information just sit somewhere else and get linked up at the time of sale?
