4. Demo applications
irst of all you should download the demo MIDlets (ePurse, Read Tag, Write Tag and MyMax
Info) to your Phone from the following Twinlinx site:
www.twinlinx.com/SDK2/MIDlets
4.1. Write Tag
This MIDlet uses the MyMax reader function to write data to an external tag. Three
functions are pre-defined
i. Write a URL into the tags memory
ii. Write a Telephone N°
iii. Write some Text
4.2. Read Tag
This MIDLet reads tags previously configured with Write Tag and depending on the data
written by TagSetter will either:
iv. Display stored URL and ask to connect to the Website or Server
v. Display stored Telephone N° and ask if you want to dial this number
vi. Display stored text
A description and installation of t e Write Tag and Read Tag demos can be found in Appendix B.
4.3. E-Purse
This demo uses the MyMax- Secure Element and is based around a simple electronic
purse where money stored in the sticker can either be debited via the PC reader or
credited via the phone. The resulting value may then be displayed on the phones screen.
This demo shows the sticker working in passive mode and active mode where a
connection is established between the phone and the secure element in the sticker.
A description and installation of t e E-Purse demo can be found in Appendix A.

5. y ax Architecture Overview
ig 1. MyMax architecture
MyMax consists of an active and passive part. The active part is used to wake up the sticker and
establish communicate between the mobile phone via Bluetooth to either the internal passive
Contactless chip or an external N C tag/card via H 13,56MHz (ISO 14443). This leads to 3
possible modes of operation.
ig 2. Operating Modes
1. Passive Mode 2. Internal Reader Mode 3. External Reader Mode
Operates like a contactless card
Energy supplied by external
reader field
Sticker is switched off – no
battery power consumption
Natural Battery off – works
when both phone or sticker
batteries are dead
Upto 2 different Contactless
chips can be integrated
Button used to wake up the sticker
Communication established between sticker and
phone via bluetooth
Internal Reader opens up a data channel between
the sticker active and passive Contactless chips
Ant-collision used to select the right chip
Data can now be read and written from the phone
to the passive Contactless chips
Passive chip security (if used) can be managed on-
line through a secure server linked via GSM
Button used to wake up the sticker
Communication established between sticker and
phone via bluetooth
Internal Reader opens up a data channel
between the sticker active and an external tag or
card
Data can now be read and written from the
phone to the passive Contactless chips
Passive chip security (if used) can be managed
on-line through a secure server linked via GSM

6. y ax battery
6.1. Autonomy
In passive (card) mode the sticker battery is not used and the secure element or passive chip
gets its energy from the external reader R field. The battery is used when the sticker connects
to the phone either to read external tags or communicate with the internal secure element.
The autonomy will vary greatly with the application need to connect to the sticker, in some
cases like an Airline boarding pass it could be twice a week or for a metro ticketing application
twice a day. The heaviest use on the battery comes from external Tag reading where the sticker
is active for longer periods of time.
In any case we estimate that around 5000 connections to the internal secure element and 400
tag reads are possible before re-charging the stickers battery as described below
6.2. Battery recharging procedure
In order to recharge the battery, the sticker must be switched to this specific operation mode. In
order to do this, the main button of the sticker must be pressed at least 3 sec until the LED starts
blinking with its specific reloading mode sequence (3 quick blinks every 2 sec) indicating that the
sticker is ready for recharging. The button should be released when this happens (pressing it too
long, ie more than 6 sec, would indeed bring the explicit pairing mode blinking sequence
described at the beginning ot the document). The sticker should then be positioned on its
charger or any active 13,56 Mhz R ID reader, button face down. If no R ID field is detected
within 30 sec, the sticker will automatically switch off.
The full charging cycle requires 4 to 6 hours. The sticker can be removed from its charger at
anytime during the charging cycle in order to either verify its charging status (it will resume its
quick blink sequence if the charge cycle is not complete) or interrupt the charging cycle. To
resume the charge, put the sticker back on its charger before 30 sec. To quit the charging cycle
and return to the normal operation mode press the button which will switch it Off. The sticker
will also automatically switch off if not returned on the charger within 30 sec.
During the recharging cycle, once the R ID field has been detected, the LED is switched off as it
cannot be seen when the sticker is positioned on the charger. When removed from the charger,
if the LED start blinking again, it indicates that the charge is not complete yet. Only when the
LED remains off, is the charge complete (provided the charger has not been disconnected of
course).
or this design version of the sticker, the Battery voltage should not be below 3.7V, once it
reaches 3.8V it is advised to re-charge.

6.3. Recharging
Re-charging the MyMax battery is achieved via an R field emitted by the USB connected
charger included in the kit.
MyMax Charger
MyMax being charged
•Plug in the charger to any USB port (alternatively in any USB AC-DC adaptor), this will
automatically start the generation of the R field (the LED on the charger will switch ON)
Place the sticker on top of the charger,
The orientation of the sticker is important, make sure that the side with the button is facing
downwards as shown in the diagram, otherwise the sticker will not recharge.
Depending on t e state of t e battery in can take around 4 ours to fully rec arge it.
6.4. Checking the state of charge of the battery
The battery level can be monitored from the application midlet MyMax Info which returns a
value corresponding to the battery voltage. When fully loaded this value should be between
4.1V and 4.2V.
If the battery needs recharging (below 3.7V), the sticker will not start in normal operation mode.
It will instead display 3 quick blinks and automatically switch off. Once in this mode the explicit
pairing sequence is also disabled. Only the battery recharging mode is available (see above).
•Go to the Menu where the MIDlet was installed.
•Click on Mymax Info
