ITEM IS SOLD AS IS AND PRICED TO SELL! DISPLAY NOT INCLUDED!  The last 2 photos show the stamp with the LED On and Off! My cell phone is not included, but shows the icon for the NFC chip as well as the current app CTT Filatelia.

Miniature/Souvenir sheet with LED (Light Emitting Diode) that lights up and blinks when placed on the back of Android and IOS smartphones with NFC (Near Field Communication) option activated! Post Office Fresh with proper protective cardboard cover. Please note that not all smartphones have this NFC technology Chip, so your phone may not cause the LED to light up ..... please check before buying as returns are not accepted under any circumstances! This is a limited edition collectors item.

For the LED to blink, your cell phone must satisfy all the following 3 conditions: 

1. The cell phone must have the NFC chip and the option should be activated!

2. You must then proceed to manully install the free Portuguese Post Office CTT app  from App or playstore and its called: CTT Filatelia

3. Now open the app.....then bring your cell phone in very close proxity to the stamp for the "chip" to activate the desired effect or activate the passive content on the stamp!

The cell phone must have the NFC chip and the option should be activated! And only then put the stamp on the back of the phone for the "chip" to activate the desired effect: that is power the LED on and off! The power to light the LED comes from the energy that the NFC chip emits....the stamp is passive and it is your cell phone that provides the "magical" and without wires energy that performs this little "miracle".

 Shipping by registered mail is included in the price!

 Returns not accepted, item is tested and in Post Office Fresh Condition as supplied by the Portuguese Postal Authorities.
