Not just a software program but your DOT Compliance Kit!
We are fortunate to enjoy high praise for PASS BOOK from our customers. We have had hundreds of compliments over the years with; “I love this program” being the most popular message.
An outstanding compliment by action, not words, Harrah’s Corp. recently purchased their 7th PASS BOOK for their hotel casino operations around the country. They researched the products out there and found that PASS BOOK is the hands down best product on the market and the least expensive for all that it accomplishes.
And, actions are Stronger than Words!
We strive to have 100% customer satisfaction but we don’t stop there. We ask our customers to submit ideas to improve PASS BOOK. And, we listen to them. Version 7 of PASS BOOK has incorporated several ideas from customers; including the tracking of the TWIC card and the annual smoke test (CARB) for vehicles.
