You can inject one under your skin and no one will ever notice, Using short-range Radio Frequency Identification (RFID) signals, it can transmit your identity as your pass through a security checkpoint or walk into a football stadium. it can help you buy groceries at wal-mart. in a worst-case scenario- of you are kidnapped in a foreign countty for example- it could save your life.
are you agree with this thing?
Is this technology already exist? Never heard this thing here in my place but I think this is ok for me if the intentions are good but if privacy will not private anymore I will not support this one. It can really save your life in terms on that circumstances but hopefully no side effect for us.
