Greetings,
I've ordered a new Interac card that has a wireless option, but my bank doesn't provide an envelope that blocks wireless signals. Does anyone know why I can buy a sleeve that blocks wireless frequencies?
Thanks,
Shane.

Do you mean "where" This depends if you're referring to wifi or those data from phone carriers.
WIFI usually operates at 2.4Ghz. But I'm not sure where to purchase this or if one exists.![]()

Yes, I meant "where", sorry.
When you say "data from phone carriers", I think you're referring to Near Field Communication (NFC). Interac Flash, however, uses Radio-Frequency IDentification (RFID).
