![]() ![]() A mechanical reader/actuator reads these paper tapes and correspondingly executes operations onto a microfluidic chip coupled to the platform in a plug-and-play fashion. A paper tape encodes information as a series of punched holes. Combining the idea of punch card programming with arbitrary fluid control, here we describe a self-contained, hand-crank powered, multiplex and robust programmable microfluidic platform. Incorporating multiple pumps, mixers and discrete valve based control of nanoliter fluids and droplets in an integrated, programmable manner without additional required external components has remained elusive. ![]() However multiple barriers exist towards low-cost field deployment of programmable microfluidics. Whether or not other places will accept it as ID will depend on the individual you are dealing with.Small volume fluid handling in single and multiphase microfluidics provides a promising strategy for efficient bio-chemical assays, low-cost point-of-care diagnostics and new approaches to scientific discoveries. You can still use a voided driving license as valid ID when flying with the TSA. ![]() ![]() The VerdictĪ punched license is no longer valid to drive with but you can fly with it! Hole punched IDs are accepted as long as all your personal information is still visible. Government-issued IDs that have been expired for less than one year are still valid identification at the checkpoint for domestic travel within the U.S. More recent information indicates that the TSA will accept an ID even if it has a hole punch. However, that Tweet seems to be out of date. In the past, the TSA had said on Twitter that hole punched IDs are invalid. But can you fly? Traveling With A Hole Punched ID You might struggle to use a punched ID to open a bank account though. If you are trying to use it in a bar many bartenders won’t mind if it has been punched so long as they can still identify you and see that you are over age to buy alcohol. Your hole-punched ID might still be valid as a form of identification depending on where you are trying to use it. A hole-punched driver’s license is no longer a valid driving license.īut can the card still be used as a form of photo ID? The whole purpose of a hole punch in a drivers license is to invalidate it. ![]()
