As discussed here in more detail, data matrix is a highly secure and extremely reliable bar code symbology that is utilized whenever circumstances call for extremely accurate tracking of items. Data matrix is deployed by governments to encode visa information in passports, by pharmaceutical companies to prevent medication errors, by surgical instrument manufacturers to track instruments, and even by the postal service to track and meter mail, among hundreds of thousands of other everyday industrial uses.

Since data matrix is an open standard with a worldwide user-base and not a proprietary technology like the majority of RF and RFID products, it is a mature and fully vetted technology that has been extensively tested, implemented, and validated by manufacturers and consumers.
