I cant see it catching on until t he price reduces and legislation is in place to cover it.
Each one costs £150, a box of 10 access fobs is around £20. The access fobs can be reused when an employee leaves unlike a microchip. You would need to anticipate high improveme nts in timeliness/productivity to.make it financially viable. If current management is so poor that so.much time is being lost to punctuality then they would be better looking at their performance management process.
Then their are the legal implications of assuring that employees are not tracked outside of work, that the chip.is deactivated/removed if employment ceases, is it implanted immediately or after probation, if immediately does the company absorb the cost if probation is unsuccesful or not, in which case how can you charge someone for a chip they dont want.
Also practically, who.implants and removes it? Would they need some kind of certification?
It feels like this is very much a 'one day' idea.
