The super-thin 5 × 5 × 0.12 mm chip fits under false fingernails and is compatible with Apple Shortcuts.

You can't pay in a cafe. At most, you can send a link or a small file through it. Today, however, messengers are perfectly capable of sending links and files.

To activate the chip it is not enough just to take a smartphone in hands - it is necessary to put the NFC-chip close to the device, and the contact point on the majority of devices will have to look for itself.

The chip is not protected from moisture and can fail in a hot bath, so you'll have to glue it on again. Chinese store sells them in sets of up to twenty pieces in one hand for a reason.

A minimum set of five NFC chips will cost $20
