General FAQ
The quoted prices are valid for 30 days. However, the validity period is subject to change without prior notice as prices are based on material costs at the time of quotation.
In general, we only load in orders with our Production Site once we have received the T/T payment. Most of the time, we do not keep stocks. Lead time is estimated to be 4-6 weeks, depending on quantity required, the availability of raw materials, and production capacity. Lead time is ONLY counted on the day the order is loaded to our production site and not as the date shown on the Purchase Order. Lead time can be affected by unforeseen issues that occurred during the production process. Nevertheless, VANSKEE will try at best, to minimize any time lost.
Terms are either Ex-Works CHINA or Ex-Works SINGAPORE. The buyer bears all costs and risks involved in taking the goods from our factory to their own premises. The buyer assumes all shipping costs.

RFID / NFC
Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects.
There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag).
The antenna enables the chip to transmit the identification information to a reader.
The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it.
NFC(Near Field Communication) on the other hand is base on RFID technology to regulate the communcation method between RFID decvices.

RFID is not necessarily "better" than bar codes.
The two are different technologies and have different applications, which sometimes overlap.
The big difference between the two is bar codes are line-of-sight technology.
That is, a scanner has to "see" the bar code to read it, which means people usually have to orient the bar code toward a scanner for it to be read.
Radio frequency identification, by contrast, doesn't require line of sight. RFID tags can be read as long as they are within range of a reader.
Bar codes have other shortcomings as well.
If a label is ripped or soiled or has fallen off, there is no way to scan the item, and standard bar codes identify only the manufacturer and product, not the unique item.
The bar code on one milk carton is the same as every other, making it impossible to identify which one might pass its expiration date first.
No contact or even line-of-sight is needed to read data from a product that contains an RFID tag.
This means no more checkout scanners at grocery stores, no more unpacking shipping boxes, and no more getting keys out of your pocket to start your car.
RFID technology can also work in rain, snow and other environments where bar code or optical scan technology would be useless.
Active RFID uses an internal power source, such as a battery, within the tag to continuously power the tag and its RF communication circuitry.
Active RFID allows extremely low-level RF signals to be received by the tag (since the reader/interrogator does not power the tag), and the tag can generate high-level signals back to the reader/interrogator.
Active RFID tags are continuously powered, whether in the reader/interrogator field or not, and are normally used when a longer tag read distance is desired.
Passive RFID relies on RF energy transferred from the reader/interrogator to the tag to power the tag. Passive RFID tags reflect energy from the reader/interrogator or receive and temporarily store a small amount of energy from the reader/interrogator signal in order to generate the tag response.
Passive RFID requires strong RF signals from the reader/interrogator, and the RF signal strength returned from the tag is constrained to very low levels by the limited energy.
Passive RFID tags are best used when the tag and interrogator will be close to one another.
Semi-passive RFID uses an internal power source to monitor environmental conditions, but requires RF energy transferred from the reader/interrogator similar to passive tags to power a tag response.
Semi-passive RFID tags use a process to generate a tag response similar to that of passive tags.
Semi-passive tags differ from passive in that semi passive tags possess an internal power source (battery) for the tag's circuitry which allows the tag to complete other functions such as monitoring of environmental conditions (temperature, shock) and which may extend the tag signal range.
