I’m using this plugin for random serials for physical products. I generated for example 5000 serials, 7 digits long using uppercase lowercase characters with digits. It generates this amount in less than one second which is pretty fast. For validation needs on website you just have to enter shortcode. I tried validation of serial numbers and the query search just takes about one second. I highly recommend this plugin not just only for it’s functionality but also for great support. Thank you!
