MyMax: Mobile Contactless Sticker
MyMax is a thin lectronic sticker designed to add contactless NFC
communication capability to existing mobile phones. It uses bluetooth
communication to connect to the phone and integrates an internal rechargable
battery to get power independent of the phone battery.
Operating modes:
MyMax offers 3 different operating modes:
1. Passive: In this mode MyMax behaves as a multichip
contactless card. Any contactless chip(s) can be put in the sticker to make it
compatible with existing applications and provide multi-application
capability.
2. Internal: In this mode, MyMax has to be switched
on. It allows to establish communication between the mobile phone and the
stickers internal flash memory and internal contactless chips.
3. Reader: In this mode, MyMax has to be switched. It
behaves as a contactless reader able to read external cards/tags and either
store received data in the flash memory or transmit it to the phone through
bluetooth interface. It can also communicate with another MyMax sticker.
