Hey! I was planning on buying myself and xssid led implant and implant it in my left hand. Between the thumb and the first finger.
I have some little question before because I want to make sure I’m not doing something irreversible or wrong
What is the life expectancy of the xssid led ? Will it just die In like 10 years or should I be good for life?
If at any point in my life I want to get it out. How can it be done.
And is it possible to implant it myself? Without anyone else. If the Answer is yes, how so, is there a tutorial somewhere?
I love it and am both glad and impressed with myself for doing it. I wouldn’t recommend it.
If I wasn’t as stubborn as I am I would have quit halfway through. There is a crazy mental barrier to overcome in doing this and I think overcoming that barrier transforms you into thinking you have to apply an immense amount of strength to get the xseries in.
With that said I recommend an installer for your first one and if you get more after that think about doing them yourself
Yep. You got to check the data sheets for the chip types on the product pages. VivoKey Spark and Apex have data retention periods of 50 years, and between 100k and 500k write cycles per memory block. Other chips like the NTAG216 have a 10-year data retention period and 100k write cycle count. I’m not sure what the t5577 chip has but it’s probably similar to the ntag216.
It’s important to remember though that there are a lot of factors and data sheets show the absolute worst case scenario. A chip that doesn’t meet the specifications in the datasheet has failed, and the manufacturers don’t want a lot of failed chips, so they will typically rate things at well below what most of their products are capable of. Maybe you got a chip that was right on the edge of failing QC, it should retain data without a rewrite for at least 10 years, more likely you got a chip that was somewhere in the middle so it could last much longer.
Flash memory charge leakage increases with the number of Program/Erase cycles, and with higher temperatures. The NTAG216 retention is specified as 10 years at 25degC, along with 100,000 write cycles. Being implanted means the chip has good temperature regulation (it will be a bit higher than 25, but (hopefully) isn’t ever going to reach 70). If you only write to it occasionally (say, <1,000 writes over its lifetime), the combination of relatively low temperature and low write cycles should result in retention that exceeds the absolute minimum specified in the data sheet. If you are writing to it more frequently, then each write will refresh the data and reset the retention period so corruption from leakage should be less of a problem.
Ok so data retention is about 10 years. Does that mean that the chip will die after ten years or I just need to write data on it again for another approximate of 10 years. If I write on it once a year should it work indefinitely?
Yes, essentially each time you write it you refresh the charge (and very, very slightly increase the rate at which the charge leaks out).
According to the datasheet you should get a minimum of 100,010 years, but you might want to consider replacing it after 80,000 years or so, just to be safe.
The read-only sections of the chip might be interesting, since they can’t be refreshed (I wonder if writing zeros over the OTP bits would effectively rewrite the page?). I have some ntag203 labels that have been sitting around for 10yrs or so, I haven’t noticed any corruption on any of them but I guess (more) time will tell.
Interesting thought. Who has the oldest functioning rfid chip that we know of? Among ourselves of course, nothing in a museum.
Amal’s “RFID Toys” book was from 2006, so presumably there might be one or two still around that are 17~ish years old. How about it @amal , are any of them dead, or still kicking?
