Been using EasyMSR for a couple months now. It’s basically a app that lets you read and write magnetic cards on your mobile device using Bluetooth. Pretty solid if you’re into that kinda thing.
Here’s what you can do: you can connect it to your card reader and swipe cards, and there’s also an option to write data to cards. And it’s got a simple interface that’s easy to figure out. And the Bluetooth connection works pretty well – haven’t had any issues with connectivity.
Look, if you need to read or write cards on the go, EasyMSR is worth checking out. It’s not perfect – the free version has ads that can get annoying – but overall it does the job. If you need more advanced features you’ll probably have to pay for the pro version.
